    What are Stink Bugs?

    Stink bugs feed on the sap of a wide variety of plants. When disturbed or crushed they produce an unpleasant odor, and this is where they get their common name. They can be a major agricultural pest, and are always a smelly and unwelcome intruder of homes.

    “I called Pest Management Systems, Inc. requesting information about pest services concerning a particular insect I was seeing in my rental property. The receptionist was very knowledgeable concerning the insect with regards to how they breed and their season for egg hatching. She also advised me of alternative approaches to handle the situation. I really appreciate the fact that Pest Management Systems, Inc. did not attempt to sell a service that probably would not have provided the results I wished (like other popular pest control companies in my area attempted to do). I will definitely consider Pest Management Systems, Inc. in the near future. ”

    What Do Stink Bugs Look Like?

    Stink bugs are also sometimes referred to as “shield bugs” due to the distinctive shield-like shape of their bodies when viewed from a top-down angle. They have long, beak-like mouthparts that they use like a straw to suck sap from plants.

    The immature bugs, or nymphs, have a less-defined shield shape, and are often a very different color from the adult bugs. Females lay their eggs in tight clusters on the surface of plants, and they appear as patches of small white dots.

    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.

    Signs of an Infestation

    Homeowners often first detect these pests by their mass invasions in the fall. Finding large numbers of live or dead stink bugs is a telltale sign of an infestation. They will turn up on sunny sides of homes where they warm themselves. Growers often detect an infestation by the damage they cause to their crops.

    If an infestation has developed inside the home or building please call PMi and we will have one of our certified pest professionals inspect to determine the severity of the infestation and come up with a game plan to take care of this invasive species.

    Stink Bug Control and Prevention

    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.

    PMi can also pre-treat for these pests as part of our Quarterly Pest Control plan before they begin infiltrating homes via small entry points in the Fall.


    They have the potential to spread throughout the country, which could be harmful to the agricultural industry, as they destroy crops.
