Elm Seed Bug Control in Pueblo, CO
Elm seed bugs are a relatively new invasive pest in Colorado that has become increasingly common in Pueblo. These bugs feed on elm tree seeds and become a major nuisance when they invade homes in large numbers seeking shelter, particularly in late summer and fall.

Our Treatment Approach
Control of elm seed bugs focuses on exclusion and perimeter treatments. We seal entry points and apply residual treatments around the exterior to create a barrier. Interior treatments may be needed for bugs that have already entered. Because these bugs don't reproduce indoors, preventing entry is the primary goal.
