Insecticides can be helpful in eliminating conenose bugs.
Treat room corners and edges, window and door frames, pet houses, and other suspected entry points with a pesticide labeled for these sites. Look for products containing permethrin, bifenthrin, esfenvalerate or cyfluthrin. Consider using a licensed pest control professional for conenose bug control.
