I have tried organic sprays, DE, and now sevin dust, but the squash bugs are still killing my zucchini, cucmbers, and mini pumpkins.
I hand pick the bugs and check plants for eggs and destroy all I can find.
I took the water hose tonight and really wet down the plants and kept watch for any bugs that came out and killed them. I read they don't like to get wet.
I also take a flash light out at night and pick any bug I find hanging out of the leaves.
I feel like I am fighting a war here.
What do you use for squash bugs?
The only thing I have found useful is to be super vigilant on the eggs early in the season, even if it means planting some sentinel summer squash to attract the early ones, and to till and remove overwintering spots as much as possible.
Wetting the plants at night encourages wilts and fungus.
I have found nothing that works but then again there is a limit to how much stuff I will use. I used 7 dust at the base of the plants early on.
I have vine borers and squash lady beetles devoring my plants now, it won't be long till nothing is left. I planted quite a bit so I have plenty in the freezer and dried. None of my other stuff has bugs, so I just consider my squash temporary.
It's wierd, when I lived in ala w my family, I don't remember getting a lot of bugs in the squash.
I still find babies quite often, and adults if go looking at the base of the plants.
I put a piece of board at the base of 2 plants and so far nothing has gotten on them during the night.
If the sevin is killing them, then they have plently of new replacements.
I have yet to get even 1 squash off my 3 plants, or any cukes from 4 plants.
Rotenone powder is our weapon of choice in that battle. Hand picking and stomping on them is only effective for the slow ones which don't hop off. But since they often like to congregate in a family group, it's sometimes possible to remove an entire leaf and destroy the whole lot under whatever size boot you are wearing.
I do not water at night but early in the morning. Water deeply at the plant bases..go away for 10 minutes and come back and pick the drying adults off the top of the leaves.
If you are hunting them and they drop off a leaf frequently they land upside down and stay that way..very hard to see because of their color and you are looking for a moving target.
When I find a "herd" of juveniles under a leaf, a quick clap and rub gets most of them before they can scatter or drop off. As you can see I am at war and very hands on about it!
If you find a mating pair, go for the larger of the 2 first..that is the egg laying female.(If you can't get both!)
Always look under dead leaves, it is a favorite spot.
Favorite over wintering spots is in garden litter. Some folks trap adults at seasons end by putting cardboard around in the area squashes were grown and collecting the bugs from under it. Oh yeah! another favorite overwintering spot is in my log home..they come in thru cracks.
A friend of mine once borrowed some half grown young chickens and turned them loose in her patch. Being half grown the were not that much into digging and did not seem to mind the taste of squash bug..it was a joy to behold!!
" As needs-MUST!!"--- in other words..a gal does what a gal has too!
I will relate my experience with Garlic Barrier. The concentrated formula they sell. I used it last year on most all the garden plants. Had the least amount of insect problems ever and never saw one squash bug. I sprayed on
7-14 day intervals. I have only sprayed once so far this year and still no squash bugs. I have never had a year in the past where I never saw a single squash bug. I feel for certain it helps. After this year I will be able to state the 2nd full season results.Whether it repels them or kills them I don't really care as long as they leave my plants alone. I have used Sevin, Permethrin and many of the other available insecticides. Jay
