It works well on Squash Bugs and other pests, and according to the promo it biodegrades quickly. However, it is also very toxic to beneficial insects, especially honeybees. If a honeybee carries Sevin back to the hive in its pollen sacks, it can kill the whole hive.
We also keep HoneyBees, so Sevin is completely out of the question when it comes to our garden.
We lost our Zucchini to the Squash Bugs this year, but were willing to lose the crop before using Sevin. We are taking other measures to protect our Squash next year.
Last year, we had a bad late season infestation in some Pumpkin vines that had grown over the garden fence. Since we had already harvested most of the garden, we let nature take its course figuring that all the bugs would die over the Winter. This was not correct. Squash Bugs can survive over the Winter in mulch, grass, and other garden debris to re-infest next year.
We had a re-infestation this year that was localized in the same area we had had it last year, but we were much more aggressive (daily inspection and hand picking) this year, and it never progressed beyond the mild stage (which was enough to get our Zucchini), but we saved other crops.
Unlike last year, we are carefully removing all mulch and debris from beds that had any problem with Squash Bugs this year. We have also allowed our chickens to graze in these beds and surrounding areas to catch any small bugs. They seem to be very thorough.
Next year, we are going to use a trellis system to keep our Squash off the ground, and allow wide spacing between plants. We are going to prune low branches so we can easily inspect and monitor the stalks for any bugs.
This works surprisingly well....
...and is fun to use! It will be even more effective if we grow our Squash vertically instead of allowing it to lie on the ground.
We (
Starkraven and myself) developed a tactic where one of us water floods from one side, and the other mans the Vac to suck up any Squash Bugs that run from the water.
This little vac is very handy, and we've used it to remove
mud daubers, wasps, and fruit flies from inside the house and kitchen. Very effective & no muss, no poison, no squashed bug bodies.
