Stink Bugs

Brown marmorated stink bugs are shield-shaped insects about 5/8 inch long with a mottled brown and gray pattern. Key identifying features include alternating light and dark banding on the antennae and along the edges of the abdomen. They have a characteristic shield or heraldic shape when viewed from above. When disturbed or crushed, they release a pungent, cilantro-like odor from scent glands on the thorax. They are strong fliers and are attracted to warm surfaces and lights.

Stink bugs become highly visible in fall when they seek warm structures for overwintering. You may notice them clustering on sun-warmed exterior walls, particularly south and west-facing surfaces. They enter through gaps around windows, doors, siding, and utility penetrations, congregating in attics, wall voids, and around window frames. On warm winter days, overwintering bugs become active inside the home and are found on windows and walls.

Fall exclusion is the most effective strategy in the Myrtle Beach area. MBPC seals entry points before stink bugs migrate indoors in September and October. We apply residual insecticide treatments to exterior walls, around windows, doors, and roofline gaps during the pre-invasion period. Interior treatments include crack-and-crevice applications in attic spaces and wall voids. For bugs already inside, vacuum removal is preferred over crushing to avoid triggering their defensive odor. Call MBPC at +1-843-555-0199 for a consultation.

Seal all gaps around windows, doors, siding joints, and utility penetrations before September, especially in areas near palmetto trees. Install or repair window screens and add door sweeps. Caulk around window frames, particularly on south and west-facing walls that warm in afternoon sun. Use a vacuum to remove indoor stink bugs rather than crushing them to avoid the defensive odor.

Brown marmorated stink bugs are an invasive species from Asia that has become well-established throughout the southeastern United States. During spring and summer, they feed on fruit trees, vegetables, and ornamental plants common in the Grand Strand area. In fall, they seek protected overwintering sites in structures, entering by the hundreds or thousands. Myrtle Beach, SC's subtropical coastal climate, with its mild winters, makes it prime stink bug territory. Significant fall invasions are common as bugs seek warm structures for overwintering near palmetto trees, salt marshes, and tidal creeks.
