Now that everyone is getting back out into the garden, we are getting lots of questions about how to prevent and treat squash pests. Our Virginia Cooperative Extension publications do a great job explaining how and when to treat-note that treatments are always more effective when they are applied at the insect life cycles or stages noted in the publications! This may explain why some people did not see results last year-for example, they may have been treating adult squash bugs which are harder to kill than nymphs.
