US Forest Service research on pesticides addresses both non-native invasive and select high priority native pests. Pesticides are often used to limit the spread of invasive insect pests such as emerald ash borer and gypsy moth. Studies have shown that trapping to identify outlier populations of gypsy moth, and applying pesticides such as Bt or Gypchek to eradicate them, has slowed the spread of the overall infestation by about 50%. Recent investigations explored the costs and benefits of varying levels of investment in the program.

Forest Service research on the use of pesticides to manage native insect pests includes research on termites and nursery pests. Many studies have been conducted searching for alternatives to the ozone-depleting soil fumigant methyl-bromide. Pesticides are sometimes also used for bark beetle suppression.
