Yes, I think you could use Sevin dust but like I said because we keep bees I'd had to take the chance of killing a colony with that stuff. Besides I have earthworms in the raised beds and that'd do them in too. It's just something you have to live with and work hard to keep them off if you want squash. Cucumbers too.so lucky said:Jim, could you put some insecticide on the ground under the plants? I'm sure you have thought of that; maybe there's not a good insecticide for that purpose anymore.
JimWWhite said:I have to agree with Ally R. above in that you have squash bugs. I lose my squash plants almost every year to them. They bore into the base of the plants and suck the life out of them and that's what you see when the leaves start turning yellow. I can't spray anything because of our bees so the only thing left is to manually kill them. One thing that does work is a trick you have to do on a regular basis. Water your plants heavily with a sprinkler in the late afternoon just at dusk. The squash bugs hate it when you water and they come out into the open. Kill as many as you can at that time. I use a long rubber band and pop 'em off the leaves. With a little practice you can get them and not tear the leaf. Then before you go in for the night take a short plank or a piece of wood about 8"x1' or so and lay it down near the base of the plant. Put a few pebbles under the corners to lift it up a bit. Then in the morning go out when it's still cool, lift up the plank and stomp the &*$#% out of them. They love to hide under things like that. Crude, but effective if you don't want to or can't spray Sevin or something like that. Oh, and look for orange egg masses on the underside of the leaves and smash them. That being said, I still lose my plants to them.
