I live in western Oregon, hence the rain question. Ants everywhere and multiple 100s of thousands of box elder bugs all summer- what's a good fix?
Products like Onslaught and Tempo SC are usually rainfast in about 4 hours. Both will give an outdoor residual of 30 days and an indoor residual of 60-90 days. Suspend Polyzone is another general insecticide, just like the previous two, but it has a different active. Unlike most insecticides, Suspend Polyzone has an added polymer that protects the active ingredient from weather, irrigation, and mechanical abrasion. Its residual outdoors is approximately 90 days.
