Brown marmorated stink bugs invade Ontario homes in fall by the hundreds to overwinter and they release a foul odour when disturbed. XtermaPro removes them safely and seals your home against further invasion.
The brown marmorated stink bug (Halyomorpha halys) is an invasive species from Asia that has established itself across southern Ontario. They're brown, shield-shaped, and about 14mm. In fall, they seek warm shelter for winter entering homes through gaps around windows, doors, and utility penetrations in large numbers. Disturbing or crushing them releases a strong, unpleasant odour.
Signs of stink bug invasion:
Stink bugs are not dangerous to humans they don't bite, sting, or spread disease. Their primary impact is the odour they release when crushed or handled, and the sheer number that can enter homes in fall. They also cause agricultural damage to fruit crops. The main concern is preventing the mass overwintering invasion.
The most effective stink bug control is exclusion before they enter sealing cracks around windows, doors, utility penetrations, and siding gaps in late summer. We also apply targeted perimeter treatments to deter entry. For existing indoor populations, we safely remove bugs without triggering their odour defence.
