This is the third year in a row for this problem. I have bought various products for spider mites, but I still seem to have them. I need help.
Spider mites are difficult to control, and thrive during hot, dry weather.
Malathion, Intercept or insecticidal soap are some recommendations. Try to monitor frequently, so that you can catch them when they start attacking, not after they have been allowed to build up. Webbing indicates a large accumulation of the insects which will be harder to kill. Clean up the debris around your garden and all your old plants when you are through for the season. Good sanitation can prevent them from overwintering in your yard.
