A shield-shaped brown bug is about to become Georgia's most annoying houseguest.
Brown marmorated stink bugs spend the summer in trees and gardens. Starting in late September, they head to homes in search of a warm place to spend the winter.
UGA Extension says the window to act is before that migration begins. That means right now.
Seal every crack an eighth of an inch or wider. Windows, doors, soffits, siding gaps, and utility openings.
Install door sweeps and repair torn screens while you are at it. The same sealing blocks kudzu bugs and lady beetles too.
And when one gets inside, resist the urge to squish. They earn their name. Vacuum instead.
Homes near woods and farmland see the heaviest pressure. Exterior treatment before late September dramatically reduces the invasion.
