Stink bugs are shield-shaped insects best known for the foul odor they release when threatened or crushed. A common native species in southeast Alaska is the common Red-Cross Shield Bug.  Introduced stink bugs like the brown marmorated species can occasionally find their way indoors—often hidden in luggage, boxes, or produce shipped from infested areas. Though sightings were once uncommon, they are increasing due to warming climates and expanded shipping routes that bring infested goods north.

Stink bugs are not dangerous to people or pets. They don’t bite or spread disease, but they can be a serious nuisance. Their odor is unpleasant, and large infestations can contaminate indoor spaces or damage garden plants.

Stink bugs often invade homes in the fall, seeking warmth and shelter to overwinter. They enter through small cracks around windows, doors, siding, and rooflines. Once inside, they may remain hidden until warm weather prompts them to emerge.

Stink bugs are most active in the late summer and fall as they prepare for overwintering. Indoors, you might see them on sunny windowsills during warm winter days as they emerge from hiding spots.

To prevent stink bugs:

• Seal cracks and gaps: Check around windows, doors, siding, and vents.
• Replace or repair screens: Make sure window and door screens fit tightly and are free of holes.
• Check items before bringing them indoors: Inspect boxes, produce, and outdoor furniture.
• Reduce outdoor lighting: Stink bugs are attracted to lights, especially in the evening.

Avoid crushing them—doing so will release their strong, unpleasant odor. Instead, gently vacuum them up and dispose of the bag immediately. If the infestation is large or recurring, contact Alaska Pest Management for professional treatment and exclusion services.
