Stink bugs are a family of insects that are well-known for the distinctively foul-smelling odor that they produce when they are touched, disturbed or smashed. Stink bugs can be green, brown, or gray and have a typical shield-shaped body with an inverted triangle pattern. Their stink glands produce an unpleasant and strong odor that helps protect them from predators, but also makes them a very unwelcome presence in and around homes. Drawn by the lights and warmth of human houses, stink bugs might become a nuisance.
Fortunately, the recommended prevention measures for stink bugs have the added benefit of being effective against other species of insects. Walk around the periphery of your home with a silicone-based caulk, looking for any tiny cracks around the foundation, windows, doors and any other potential entrances in siding or around pipes. Since they are often drawn to light, it might be helpful to replace any ripped screens, and installing seals around windows and door sweeps will not only keep many insects out, but also increase home energy efficiency.
Late summer and early fall are stink bug season. If stink bugs are found inside of the home, do not smash them! Instead, it is preferable to suck them up using a vacuum (make sure to remove the bag later), or you can make a very effective and non-toxic homemade stink bug spray consisting of a 25-50% detergent solution mixed with water. Lavender oil, vinegar, and tobacco mixed into water will also kill stink bugs when applied by spray bottle.
If these two home remedies aren't sufficient, it is recommended to use repellent around the outside of the home. Stink bug repellents can be found in large home and garden stores, or consult a professional pest control agent. Remember to carefully read any insecticide instructions to avoid harming family members and pets.
