Signs you're dealing with seasonal invaders — not something else.
Box elder bugs on warm south siding
Black-and-orange bugs clustering on south- and west-facing walls in October are pre-overwintering aggregations.
Cluster flies at sunny windows
Sluggish flies appearing one or two at a time at south windows on warm winter days are overwintering inside walls or attics.
Asian lady beetles in window tracks
Orange beetles with variable spots showing up indoors in November have already moved into wall cavities to overwinter.
Pine seed bugs near windows and doors
Slim brown bugs with leaf-like hind legs are western conifer seed bugs — strictly nuisance, no biting or stinging.
Yellow staining on light siding
Box elder bug fecal staining on light-coloured siding can be permanent. Pre-treat in late summer to prevent it.
Cluster of bugs at attic vents
Aggregations at louvres, gable vents, and ridge caps signal the active entry route — treat the perimeter there.
The methodSeasonal Invaders
Seasonal Invaders
is a process, not a spray.
Late-summer/early-fall perimeter residual application along south- and west-facing exterior surfaces, with attention to attic vents, soffit gaps, and window frames. Indoor vacuuming for already-arrived invaders; treatment is fundamentally preventative.
Time the treatment
Late summer through early fall is the window. Treatments applied too early lose effectiveness before invaders arrive; too late and they're already inside the structure.
Perimeter application
Residual product applied along south- and west-facing exterior surfaces, with focused attention to attic vents, soffits, and window frames where invaders enter.
Indoor cleanup
Where invaders have already entered, we recommend vacuuming and sealing visible entry points. Insecticide indoors offers little benefit for these species and isn't standard.
One flat fee. No upsells, no surprise site charges.
Single-visit perimeter treatments are flat-rated by property size. Multi-building rural properties scale up. Recurring annual treatments timed for late August / early September are priced lower per visit.

Single late-August perimeter treatment along south and west elevations, with focused work at the attic louvres and a soffit gap above the kitchen window.

“Used to vacuum a coffee cup of bugs every other day. Now I forget they're a thing.”
