What Do Stink Bugs Look Like
Stink bugs are described in several different ways. They are characterized as both “large, oval-shaped insects” and “shield-shaped insects.” Adult stink bugs can reach almost 2 cm in length. They are nearly as wide as they are long. Their legs extend from the sides, so this makes the adult bugs appear even larger. The brown marmorated stink bug is a brownish stink bug. It has lighter bands on the antennae and darker bands on the wings.
Adult stink bugs are good fliers and fold their wings on top of their body when they land. Nymphs do not have fully developed wings. The wings appear when the nymph becomes an adult. Fully developed wings are a way to identify adult stink bugs.
Immature stink bugs, called nymphs, are very tiny when they hatch from their eggs. Nymphs of the brown marmorated stink bug are yellow and red. As they grow, the yellow fades to white. They have bright red eyes during the nymph stage of their life cycle. The nymphs molt or shed their skin five times. Each time a stink bug nymph molts, it becomes larger. By the last molt, the nymphs are almost as large as adult stink bugs.
To prevent stink bugs from entering homes and buildings, seal cracks around windows, doors, siding, utility pipes, behind chimneys, and underneath the wood fascia and other openings. Typical entry points include around door and window frames, electrical outlets, light switches, ceiling fans, skylights and ceiling light fixtures. Use a good quality silicone or silicone-latex caulk. Damaged screens on doors and windows should be repaired or replaced. Stink bugs are attracted to light, so change exterior lighting to less-attractive yellow bulbs or sodium vapor lights.
If you need to know how to get rid of stink bugs that have already entered a home or building, a vacuum cleaner can aid in the removal of live or dead stink bugs. The bag must be discarded to prevent odor from permeating the area. After stink bugs have entered the structure, it is best to isolate the affected room or rooms by sealing the bugs out. If an infestation has developed inside the home or building, Arch Pest Services should be called to evaluate and assess the problem. We can also pre-treat for stink bugs in the late summer or fall just prior to bug congregation.
