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

Stink Bugs are a recurring concern across the Denver Metro Area, and Denver is no exception. Denver's mix of mature urban tree canopy, alley networks, and dense multi-family housing creates ideal pest habitat. The South Platte River corridor, Cherry Creek, and Sloan's Lake all support wildlife populations that overlap with adjacent 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 Denver specifically, dense multi-family housing means pests move building-to-building through wall voids and shared infrastructure. restaurant and tourist density supports established cockroach populations. mature tree canopy provides squirrel and roof-rat highways. greenways and parks act as wildlife reservoirs feeding into the surrounding blocks. compounds the picture — meaning Denver homes face stink bugs pressure that's distinct from the metro average.
EPC has run stink bugs jobs across every corner of Denver. Denver's housing ranges from 1900s-era brick bungalows in West Highlands and Wash Park to mid-century ranches in Hilltop and modern townhomes in RiNo. Older homes have rubble or stone foundations with countless micro-entry points; newer construction has tighter envelopes but is vulnerable through garage doors and utility penetrations. Our approach is brown marmorated and conifer seed bugs that overwinter in walls.

Why do Denver homes get stink bugs?
Dense multi-family housing means pests move building-to-building through wall voids and shared infrastructure. Restaurant and tourist density supports established cockroach populations. 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.
What are the first signs of stink bugs in a Denver home?
The earliest indicators are: shield-shaped brown bugs at sunny windows, especially February–April; foul cilantro-like odor when bugs are crushed or threatened; bugs emerging from light fixtures, electrical outlets, ceiling vents. Catching any one of these early usually means a smaller, cheaper job than waiting until the problem is obvious.

What's the smell?
A defensive chemical released when stink bugs are threatened or crushed. Some describe it as cilantro, others as rotten almond. It clings to fabric and skin and takes hours to dissipate.
Do they bite or damage anything?
No bites, no structural damage. They are a serious agricultural pest (orchard fruit damage), but indoors they're a pure nuisance.
