I'm trying to figure how it works. For example if I spray and then a bug walks across the place where I sprayed once it's dried how does that effect and come in contact with the bug is it just through its feet? Also how long will the product stay there for?
It does depend on the type of insect but in general the dried residual of Gentrol IGR will last for 14-120 days. Be sure to read the product label to see how often you should retreat for the pest you are targeting.
