I sprayed some Sevin the other day after some heavy rainfall. Shortly afterwards, it rained a bit more.
Today, in the patch, I saw what looked like a wasp, but it was red. I had heard of squash vine borers before, but had never seen a picture. When I looked at one today and saw that they are reddish, I got a bit nervous.
So, I am wondering how long I should wait to spray again. I wasn't going to do it until next week. But, now I'm worried that the first spraying might have been washed away by the rain before it had a chance to stick to the leaves. And, I don't want my innaugural growing season to be spoiled by a stupid bug!

Crammed, ive never found sevin to be effective at keeping SVB's away. Alot of people here use Warrior, or tasltar (im pretty sure that's the name). ive heard that sevin washes right off after a rain. yes the moth is red and looks like a wasp.

Should I wait to spray, since I've sprayed two things on in the last four or five days. I don't think I want to overload the leaves with residues. Or, is it worth the potential risk to the plant to save it from the potential risk of the squash vine borer?

well if the sevin already washed off, it wouldnt matter if you sprayed again. Steve will chime in hopefully and save the day on this one. Either way, you need to get something other than Sevin on SVB's because it wont do anything to stop them.

Warrior T is sold in Canada as Matador. Unfortunatly it requires a pesticide licience to purchase and only comes in large quanties. A good product you can purchase, is a product called Ambush. It is available at most garden centres. It is labeled for Cuc beetles, Squash bugs and SVB. If you have trouble finding it, e-mail me directly. We sell it in our garden Centre.

Ambush would work well. Active ingredient is Permethrin. Noted in case you need to find an alternative brand. Warrior is aka Lambda-cyhalothrin which ia marketed under many other trade names here in the US. Talstar is my preference...look for Bifenthrin as the active ingredient.
Most of what we notice "missing" after a rain is the ineffective binders found in Sevin. Thus the active ingredient (carbaryl) is probably still present. This doesn't matter since as noted Sevin does a poor job with Squash Vine Borers.
Get a hold of Permethrin, Bifenthrin or Lambda-cyhalothrin & use one of them instead...SOON.
In an experiment last year we discovered that heavy Merit (Imidacloprid) drenches controled SVB larvae in the stems. Needless to say there was still major & unacceptable vascular damage. The point is that some rescue is possible even after the adults have laid eggs & the eggs have hatched. Timing in this case is critical.
Good luck!

It looks like I should be able to find Ambush pretty easily. It's marketed in Canada by "Wilson", a brand that I have seen around just about everywhere (Home Depot, Canadian Tire, etc.).
So, it looks like that's what I'll be doing tomorrow morning. I'm also thinking that it might be a good idea for me to start using a seperate sprayer for foliar feeding and insecticide/fungicide spraying. But, they sure are pricey for a bunch of plastic.

No need for a seperate sprayer. I quite often apply my foliar fert with my inceticied and/or fungicide.
