Is Jenny around anywhere? Is it time for an Insect Advocate 2007?
I've got cucumber beetles eating up my sage, and I don't know what to do. I'd say about half of the leaves on my (rather large) sage plant have been perforated with holes. Is there a way to get rid of them short of pesticides?

Well, FlyingCow -- we pick them off by hand, or let our chickens run in with the plants and pick them off (they help a lot with ridding the garden of insects).
Another thing you might try that has worked for some other beetles we've been fighting -- put out a container half-full of water (we use one of those plastic tubs you get two gallons of ice cream in at the store). Set it next to the plant. The beetles are attracted to the water and fly into the water, but then can't get back out.

Just be sure you have some place that's not the garden to keep the chickens when they're not eating bugs. Once they finish the bugs off, they'll start in on the plants.

Too bad rabbits don't eat japanese beetles... instead I just have two pests.
Seems as though the white lawn grubs I found earlier this year were likely japanese beetle grubs. Lovely. Doesn't look like the Grub-X did a whole lot of good - and I read that japanese beetle traps often do more harm than good.

Disclaimer & Reminder: My handle is a Red Prophet reference, not a signal of any kind of vendetta toward insects. However...
I do have some bug questions.
First, I think a nest of yellowjackets is beginning to form in our roof. I've been seeing them flying in and out of a corner in the eaves near the back door. This house (a rental with a lazy landlord) has vinyl exterior, and I'm a little worried about destroying the siding with attempts to locate and/or destroy said nest. How should I plug the hole or rid myself of the little beasties?
Second, in August 2006, I found a very large (6-7 inch resting wingspan) and very beautiful yellow moth in my car one morning. Remembering The Girl of the Limberlost, I hoped to catch and save it since I know they have a very short life. I planned to give it to my mother's kindergarten class in Seattle. Unfortunately, I must have gone about it all the wrong way. I trapped the lovely creature in a shallow box with a lid and expected it to just expire and harden. Not likely. It made a real ruckus fluttering around in the box for a long while, so I put some alcohol on cottonballs and poked them into the box. Eventually the moth stopped moving, so I looked inside and the poor creature had laid her eggs in there! They were small, bright yellow balls and they looked like those little moisture-absorbing granules that come in packets with DO NOT EAT written in six languages on them. I took it all with me to Seattle a few days later and my mom ended up burning the whole container because she was really worried about the eggs hatching and causing some kind of cross-country caterpillar infestation. I live in the North Carolina Piedmont Triad area. I'd like to know a) What kind of moth was it? It was almost completely a canary yellow with a thick, fuzzy body and a few sort of grayish spots on the wings. b) How should I have handled the situation? Obviously the moth needed to lay eggs prior to being caught and pinned, but I had no clue she hadn't yet. Her body shrank quite a bit after she laid the eggs, which was interesting to note, however I wouldn't be able to tell the difference with another type of moth. Should I have released the eggs into the woods? Would they have survived? What is the best way to quickly kill and preserve a moth or other insect for scientific study? Is it right to do so?

Yellowjacket control - I'm afraid that these little critters will be quite aggressive when defending their nests. I suppose you could try plastering over the hole at night, but would that be any kinder than using poison? Are the yellow jackets really bothering you? Are they a threat to you and your family? If they are not, you might try to just live and let live until winter, when it is quite easy to repair the hole without being stung.
Unusual Moth - try looking up your moth at whatsthatbug.com, one of my favorite insect advocacy and identification sites. Or, try insectguide.net. Both are excellent. As far as preserving insects for posterity, the best thing you can do is kill them quickly and pin them. For my daughter's 4-H project, we have a kill jar (basically a jar with a little plaster-of-paris in the bottom). You then saturate the plaster with poison. You can use nail polish remover. After the insect dies (and it should be within a couple of hours), you must pin it right away before it gets too stiff. For moths, you pin directly through the thorax. Then, you should arrange the wings. If you're really interested, I suggest checking with your local entomology department. I don't know if your eggs would have survived after being exposed to the alcohol. And as far as the contamination concern, this is where proper identification is really helpful. It's true that insects from one area can cause huge problems if imported to another. In my state of Indiana, we are having trouble with the Emerald Ash Borer, a very pretty beetle that destroys ash trees. To control its spread, you are not allowed to transport firewood from one part of Indiana to another! If your moth was a pest species, the Seattle agriculture and natural resources department might not appreciate you bringing viable eggs into their area!
Next time, I would say identify the insect so you know what it is. And if you still want to preserve it, kill it humanely. Conversely, you could capture it in a bug cage and release it after sharing it with schoolchildren.
As far as the morality of killing insects... Most insect species are in no danger of being wiped out. While I, personally, do not like killing insects, I am okay with a few individuals being taken for the purpose of study. I also understand and appreciate the necessity of killing pests, dangerous insects when they are truly a threat, and insects used as food. It's up to you to determine your own relationship with the insect world.

So, Jenny, what's your advice on japanese beetles? From what I've seen, my best bet is to just pick them off by hand and drop them into soapy water.
Since I'm not home often, and usually water my garden just before sunset (or later), I'm really not around to pick off the beetles. And apparently, japanese beetle traps often end up attracting more beetles.

Well, I've been trying to figure this one out myself! If you don't mind threatening the beneficial insects, you can use an insecticide.
The really bad thing about Japanese beetles is that they secrete an aggregation pheremone, which causes them to hang out together. The plants they chew also release a chemical distress smell that attracts the beetles. So, once a plant is damaged, it is in great danger.
I did some research on Japanese beetles, and found the following: there is actually a "stop eating now" pheremone secreted by the beetles, but scientists aren't able to produce it for commercial use yet; Japanese beetles are most active in direct sunlight and at the tops of plants, in fact becoming disoriented in the dark; plants in the sun because their leaves are chemically sweeter to the beetles; certain wasp, fly, and nematode species do parasitize the beetles and their grubs; and I directly observed them following a sccent path laid down by their fellow beetles across the field to my grapevines.
Here is what I did: I picked off all the beetles I could and drowned them in soapy water. In the early morning after a rain (the rain washed most of them away and cleaned off the scent trail), I put screened things like colanders over the smaller and sensitive plants. I turned my outdoor chairs upside down over the bigger plants. My theory was that it would be harder to find the plants, therefore making other areas more amenable to the beetles traversing through my land. So far, this has worked. The scent trails moved to the strawberry bed.
My suggestion for someone who wants to fight without pesticides would be to use some sort of barrier, like a mosquito netting that lets in light and air and water, for when the Japanese beetles first emerge and start aggregating. They might land on the netting, but they wouldn't have anything to eat. They would quickly move on. Also, if you could shade or hide sensitive plants in some way, that might be good. You could consider using the Japanese beetle traps at an edge of your property far from your desired plants to encourage the beetles to change their flyways in that direction. I'm really dubious about those pheremone traps, though. I've read you want to encourage your neighbors to get them! I also had good luck at my last house, where I grew 4 o'clocks. They are supposedly poisonous to Japanese beetles. I also found out that geraniums make Japanese beetles paralyzed. They'll eat the petals and get drunk, I guess. But they don't learn to avoid them. So if you can plant 4 o'clocks and geraniums, and not mind them getting eaten, they might help. Also, note what weeds are eaten by the beetles and leave them alone if they are far enough away from your special plants. They'll be decoy plants for the beetle flyway. Overall, your tactic should be to make your plants less enticing than the other ones in your area. It is also suggested that you treat your lawn when the beetles are in their grub stage to prevent such large emergences in the summer. You can choose pesticides (which lawn companies would love for you to buy) or try parasitic nematodes (little wormy things that are harmless to people).
To review, Japanese beetles
LIKE: grapes, roses, apples, beans, and others; tops of plants; plants in the sun; other Japanese beetles; plants that make them drunk - geraniums and 4 o'clocks
The first contains 4 basil plants (only 1 with large leaves), sage, rosemary, thyme, oregano, 4 pepper plants, 3 dill plants, and 5 marigolds in the center. It's a happy, slighly crowded box, without much of an issue. I'm starting to get aphids on my dill and I need to spray it down with soapy water, and my sage has started to get spots (cucumber beetles, mainly). The one large-leaf basil is starting to get hit by japanese beetles.
Almost everything in the first box I can probably protect with screening pretty easily.
The second box is my bigger problem. I have 1 gargantuan grape tomato plant (which would take over the whole box if I let it, but it's tied up), two large leaf basils, 2 regular tomato plants, 3 cucumber plants (which climb out from the edge of the garden up a 4-foot diagonal trellis made of bird netting), and five marigolds in the center. My girlfriend and roommate call this box "Jumanji".
Right now, the cucumbers are suspended on a rectangle of bird netting about 4'x4' extending diagonally up from the box at about a 40 degree angle. They have very large leaves that are starting to be eaten by japanese beetles. I can't cover the whole thing in mosquito netting, because then the bees can't get in to pollenate the flowers.
Because I work from 9 until 6, I only see my garden in full sun during the weekends - when I'm also often away from the house - making picking the buggers off very difficult.
I'll try getting some 4 o'clocks and geraniums to see if that will do the trick.
I may be able to screen the basil, though. I'll give it a shot.

A word on traps, I didn't use them last year (since they sold out in my area) and my dahlias and virginia creeper were denuded by Japanese Beetles. This year I'm using them, and I don't have any way to put them the recommended "30 feet from desired plants" so I just stuck them in the middle of the yard. That seems to have worked.
In the afternoon the beetles swarm all around the traps and eventually find their way inside. There is some evidence of beetle damage to some of my plants, but nothing to cry about. I'd suggest getting pheremone traps and just putting them as far from your "desired plants" as you can get them. You might draw beetles that wouldn't have come to your garden in the first place, but you are drawing them to the trap and not necessarily to your desired plants. At least that's my experience. You will certainly see more beetles if you use traps, but that doesn't mean they are doing the same damage they would in a smaller population left unmolested (i.e. without traps.)

I think if you're already dealing with a very high volume of beetles, the trap won't necessarily make it worse. I'm dealing with a very light volume and don't want to attract any more.
I've been killing one or two a day the last week or so.

Well, my beetles have moved on to the vegetable garden, where they are happily munching the kale and turnip greens. I am fine with that. They haven't hurt the other veggies much at all. Faerygirl does go out and harass them every day, giving them baths in a bowl of soapy water (that's what we tell Little Crow is happening, since he loves the beetles and wouldn't want them to be killed).

Jenny, one of your friends bit me on the inner thigh a few days ago. It's quite red and swollen after 3 days, and I have tender lymph nodes near it So far, there is no blister or distinct hole in the center.
I spent a lot of time outside back when it started, wandering through tall grass, whacking weeds, and working in an old shed. Who only knows what kind of bug decided to chomp on me. I'm leaning toward spider, but I'll probably never know.
I'm monitoring it, to be sure it doesn't rapidly worsen. Hopefully it will clear up soon.
Tell them all to stay away from me, or I'll soon wage chemical (Raid) and conventional (flyswatter) warfare on them. :evil eyes:

Right, and I'm well aware it's likely NOT a brown recluse bite. I made it clear that I have no way of knowing for sure, because I didn't see the bite occur.
I can say for sure that it's not a flea (or louse), tick, mosquito, chigger, or ant bite. It's also not a sting from a wasp, bee, or hornet.
But I'm willing to admit it could be a bad infection in a chigger or mosquito bite. Ahh, the wonders of never solving a mystery.

Tstorm, could be a sting from a small bee. The little solitary bees are quite aggressive, and their stings hurt. It could also be a bite, as you say. If your lymph nodes are swelling, I'd definitely watch it, and if they don't go down, you need to get things checked out. Sorry that you had a bad experience.

Yeah, I'm planning on a check up right now. The lymph nodes are still just as tender, and the inflamed area is getting larger. I traced a dashed line around it with a pen yesterday morning, and no doubt about it, it has grown larger in the past 24 hours. This is nearly five days after I noticed the itchy spot. Time for a doctor's visit, expensive though it may be.

Update: Went to the doctor, received prescription for antibiotic and steroid (to reduce the inflammation). Also received instruction to apply heat a few times a day, although that's difficult when I'm at work for 10 hours or more. I do my best, and I won't miss any of the medicine.
Four days later, the bite is rapidly vanishing. The swollen lymph gland(s) are gone. I can still see little purple veins near the bite mark, but there's no more puffiness or inflammation like there was on Monday. I think those little "spider veins" (no pun intended) will go away after a while.
Thus ends the saga of the unknown insect bite.

I hate wasps getting into my apartment. I think there has been two or three. Maybe 2 in my room and it's VERY SCARY! Is there some sort of way to repel them? I feel guilty about smashing them, but they are varelse (sp) and I have no choice. They are vaguely cute scary dominatrixes of the insect world.

It's actually easy to catch a wasp for release. Just place a cup over it against a wall or floor or ceiling. Then, slide an index card or something of similar thickness beneath. Be careful not to pinch the wasp's legs. Gently carry the apparatus outside (cup upside down on the index card). Tip back the cup and retreat. The wasp will gladly fly away.
Wasps are actually rather large to be getting into your apartment. Find the hole or open door or window where they are coming in, and screen or otherwise put up a barrier.
If you know what kind of wasps they are, I can tell you more about their habits to help you troubleshoot where they are coming from and why they are in your apartment.

I have discovered the biggest bugs since moving to Virginia. We have these green beetles the size of marbles that fly around aimlessly until they run into something. I Honestly think that's the way they navigate. They're funny to watch, but they hurt when they fly into your head.
The bite has healed. There's still a small mark on my leg, smaller than a typical chigger bite, which should disappear soon. Aside from an unpleasant side effect of the antibiotic, no complications resulted from this.
More insect fun...
This weekend, I'm in KC and I'm staying at a friend's house. When I woke up this morning, one of the first things I did was go to my duffel bag for clothes. I picked up the old clothes on top of the bag first and set them aside. Then I picked up my jean shorts and ... underneath the shorts, sitting inconspicuosly on a white shirt, sat an average-sized fiddleback spider.
Yeah.
We regarded each other for a couple of minutes. He didn't move, I didn't stop looking at him. I didn't want to lose sight of him in the event he scurried deeper into my duffel. He just kinda sat there, looking up at me with his six eyes. I, still sleepy-eyed, sat there and looked back at him, forcing my eyes to REALLY wake up.
Not wanting to lose sight, I went into gecko mode, used one eye and hand to fold up a sock as a weapon. In my past experience with these, I know it doesn't take much of a blow to kill them. One hit, and he's down. Wounded. I put him in a tupperware container, sealed it, and left a note:
"**DANGER** This is a Brown Recluse spider. It is poisonous. Please do not disturb, throw away, or set loose. I may need it for medical evidence."
I packed this bag and left it overnight in my apartment back home, so it's possible this guy is a hitchhiker. It's also possible he crawled into the bag while I slept last night. This is the same bag I used the weekend I received the bite, two weeks ago, staying at my parents house. At any rate, hitchhiker or not, he's earned an all-expenses-paid trip back home...I'll call him an "insect of interest" in an ongoing investigation.

I have a question. I've quit sitting out on my deck because of the mosquitoes, and my heightened fear of arthropod borne diseases since my son's Lyme has had such a huge negative impact on his life. Is there any bug zapper or other device that can make it safe to do that again? It's beautiful out there but each time I spent 10 minutes admiring the bats and the foliage and the darkening sky, 3 days later I would be covered in itchy bumps that turned into sores, and due to my diabetes each sore on my lower extremities would last weeks to months, turn into an ulcer, and threaten the need to amputate my feet. 10 minutes of nature's beauty isn't worth that.
The idea of killing insects instead of enjoying their company might horrify you. If so, I apologize.
On another thread I recently read pooka's simile that she was drawn to something like a mosquito to a CO2 generator (or something like that). Are there new attractors on the market that actually keep an area clear of mosquitos?

Current bug zappers don't work on mosquitos. An entemologist did some body counts and found few hundred other insects for every mosquito. And the overwhelming supermajority of mosquitos killed were males, which don't bite.

Tatiana, it might be easier to just get some mosquito netting and build yourself an enclosure on your deck.

Noemon, that would make it feel a lot less like being outside, I think. For instance, looking at the stars through a telescope is one of the activities I like to do out there. I think the netting would cut way down on the light transmitted.
I have thought about a screened porch with cat access, so they can go sit out there whenever they like. I'm sure they would love that.

I have an insect issue I could use some help with. We have a couple bushes in our front yard that the bees seem to love (a fairy duster and a ruellia). I'm happy that the bees seem to like our plants so much, but I'm concerned about pruning them. I don't want to upset the bees (there are a LOT of them in the fairy duster especially - dozens and dozens every time I look) and get stung, but I do need to do a little bit of pruning since the bushes are starting to overhang the sidewalk...

ludosti, pruning is best done at a time of year when a plant is not in bloom. For this year, forget pruning and leave it be. In the dead of winter, then prune it well back, so that with spring growth it will be the ideal size.
aspectre, I would love one of those star wars mosquito zapper. Even better is the fact that it doesn't indiscriminately kill the good bugs. I can't wait until those go commercial.

Alternately, if you absolutely must prune during the blooming times, you could look for beekeepers outlets and buy a smoker. The smoke makes them groggy and ill disposed to sting. It's still risky, though, to give all the bees the right dose of smoke. Usually it's done with a hive box to rob the honey.

Unfortunately, it's warm enough here in AZ that they bloom all year round. I'll have to try looking first thing in the morning (like 6 or 7am when it's still cold) to see how active they are and see if I dare trying to prune...

ludosti, most nectar feeders can be nudged gently. I recommend starting gently with a few branches, see how that goes. Most of the time, if you are calmly going about your business, the pollinators will calmly go about theirs. Just to be on the safe side, you might want to button up with gloves, long sleeves, and pants with legs tucked into boots. I bump into my wee wasps and bees quite often in my gardens, and I just say excuse me and they buzz off disgruntled in the opposite direction. Bees aren't really inclined to sting you unless you are messing with their hive. And the insects you are dealing with are probably so full of nectar it wouldn't be worth the effort to them (one of the things smoking does is get the bees to gorge on honey, and that makes it physically harder for them to sting!).

I'm glad to hear that the bees may let me prune. I know that bees normally aren't inclined to sting (since doing so kills them). I have been able to weed around (and under) the bushes without any problems. I'd get a little nervous when some of the bees would come land on me, but they'd fly right off again. I'll try doing some pruning early Saturday morning (when it's still cool out and hopefully there aren't as many around) and see what happens.

Things went well this morning. There were considerably fewer bees first thing this morning and I did my best to be as calm and efficient as possible (which was still hard with them milling around me). I was silly and was even talking to the bees while I worked, apologizing for disturbing them and explaining that I needed to do this so we can continue to co-exist happily.

Nothing silly about talking to bees! Throughout history, beekeepers have talked to them. I certainly do when hubby and I go out to tend our own beehives. And who knows? Maybe your talking calms you, too, and helps your chemical signature be less threatening. Biochemistry is so complex, and insects live in a world where chemical sensations are very powerful. We don't sense a fraction of the things an insect does. Or, on the other hand, maybe they just appreciate you making an effort to work with them instead of saying "Eek! A bee! Go away! Or I'll get spray!"
