Squash bugs: alternative to carbaryl and pyrethrin

Posted by idgardener Idaho (My Page) on

Squash bugs killed one of squash plants already, but I'd like to save my cucumber, zucchinis, and melon plants.

I tried a pyrethrin spray, but it didn't seem to have much affect on them. Maybe I should try pyrethrin again, in a higher dose?

I'm really not crazy about using Sevin/carbaryl on vegetables. I've read that it is a broad spectrum insecticide, and I have other plants that need bee pollination. I've also read that it is a carcinogen.

I have too many plants to kill all the squash bugs by hand. It would take a whole day unfortunately.

Sevin does not efficiently kill adult squash bugs anyway. They seem to be impervious to it. And I've never seen a recommendation for any other kind of spray that kills them.

So if you want to control them, you might plant some yellow or Hubbard squash, trap crops, a bit away from your garden and let them feast there. Those are their favorite cucurbits and they'll usually leave the others alone if these are available. Get one of those hand vacs and clean the squash plants a couple of times a week to keep the numbers down.

I squish when I water and remove all eggs from leaves that I find. Last year they ran me over until I began to squish them. My husband used Sevin power with no results at all. I have never tried squishing because neighbor said the smell would draw more...it doesn't...must be an old wives tale!

Good luck...I found eggs on my Burgess Buttercup Squash and the leaf of a watermelon nearby this morning.

I'll try the soap and water one tonight.

Planting later (June) has worked for me the past three years ... just luck?! There are a few bugs when I water the plants & they come up from the ground where I see & 'squash' them. Some say a late planting by-passes most of the egg laying ...?
