Stink Bugs Control
in Boulder.
Professional stink bugs treatment across Boulder. Brown marmorated and conifer seed bugs that overwinter in walls.

Stink Bugs are a recurring concern across the Denver metro, and Boulder is no exception. Boulder is wedged against the foothills with the city's western boundary effectively up against open space and protected wildland. Boulder Creek, Wonderland Lake, and the extensive open-space ring create constant wildlife corridors into residential blocks. Stink bugs love attic spaces, wall voids near windows, behind shutters, in soffit cavities, and around window framing where they can find narrow gaps and protected overwintering harborage.
Brown marmorated stink bugs have established along the Front Range over the past decade. Older homes with original wood windows and heavy soffit detail experience the worst overwintering populations. In Boulder specifically, foothill proximity drives intense rodent, squirrel, raccoon, and bear pressure. student rental concentration near cu drives bed bugs and roaches. environmentally-conscious clientele expects eco-first methods. older hill homes with original construction face heavy carpenter ant and overwintering pest pressure. compounds the picture — meaning Boulder homes face stink bugs pressure that's distinct from the metro average.
EPC has run stink bugs jobs across every corner of Boulder. Boulder housing is a mix of expensive foothill-adjacent estates, dense student rental housing near CU, and older Hill and Mapleton neighborhoods with original 1900s construction. Student rentals see disproportionate bed bug and cockroach pressure due to high turnover and shared housing. Our approach is brown marmorated and conifer seed bugs that overwinter in walls.
