OOps! over looked this one!
**problems with insects with several squash **
Try dusting the stems with rotenone if you can find it. some of the pyrethrin or permethrin sprays work as well. Squash vine borers are worse around a full moon. The eggs are laid by a stupid little moth. If you can get the squash up and teh stems thick and tough before the next full moon, they’ll have a better chance. I think the full moon this month is the 20th.
Thanks, I’ll be on the lookout for rotenone.
