Stink Bugs: A Brief Introduction

Stink bugs, scientifically known as Pentatomidae, are shield-shaped insects with a distinctive odor. They are native to Asia but have become widespread in North America, Europe, and other parts of the world. These insects feed on a variety of plants, causing damage to crops and ornamental plants. Their invasive nature and ability to emit a foul smell when threatened or crushed have earned them the name "stink bug."

  • Temperature: As the weather turns colder, stink bugs look for warmer places to overwinter, such as your home.
  • Food source: If you have plants indoors, stink bugs may be attracted to them as a food source.
  • Shelter: Stink bugs are looking for protected spaces to hide and lay their eggs. Cracks, crevices, and gaps around windows, doors, and siding provide ideal hiding spots.

Identifying Stink Bugs in Your Home

Stink bugs are easy to identify due to their distinctive shape and color. Adult stink bugs are about 1/2 to 5/8 inch long, shield-shaped, and have a brownish-gray or greenish-brown color. They have six legs and antennae that are about as long as their body. Nymphs, or immature stink bugs, are smaller and have a reddish-orange color.

Guardians - The brown shield-shaped insect crawling out from behind your window trim right now is the Brown Marmorated Stink Bug — Halyomorpha halys. It arrived from East Asia in the late 1990s, first detected in Allentown, Pennsylvania. Within two decades it spread to 46 states and became one of the most damaging agricultural pests on the continent.  Here's the problem. There's a native insect that looks almost identical — and it's one of the best predators your garden has.  The Spined Soldier Bug is the same shield shape, the same mottled brown coloring, roughly the same size. Most people can't tell them apart, so they kill both. The difference is in the shoulders. The Brown Marmorated has smooth, rounded shoulders. The Spined Soldier Bug has sharp spines jutting out from its shoulder line. That's the fastest ID. Look at the shoulders.  The invasive one feeds on over 100 crops — tomatoes, peppers, apples, peaches, corn. It pierces the skin and injects digestive enzymes, leaving brown necrotic spots that ruin the harvest. It costs U.S. agriculture hundreds of millions per year.  The native one hunts. It eats caterpillars, beetle larvae, Colorado potato beetles, cabbage loopers. Gardeners actually buy them as biological control. One Spined Soldier Bug can take out dozens of pest insects per week.  One is destroying your harvest. The other is defending it. Check the shoulders.  #StinkBug #InvasiveSpecies #GardenPests #BackyardWildlife | Facebook

Stink bugs are attracted to light and plants. Keep outdoor lights off when possible, and bring indoor plants inside during the fall and winter months to reduce the attraction of stink bugs.

Vacuum and Remove

If you find stink bugs indoors, vacuum them up using a handheld vacuum. Empty the vacuum bag or canister outdoors to prevent the stink bug odor from lingering in your home. You can also remove stink bugs by hand, but be cautious not to crush them, as this will release their distinctive odor.

Professional Pest Control

If stink bug infestations are severe, consider hiring a professional pest control service. They have access to specialized treatments and can provide expert advice on preventing future infestations.

Preventing Future Stink Bug Invasions

Preventing stink bugs from entering your home in the first place is the best strategy. Here are some tips to help you achieve this:

Time of Year Prevention Tips
Spring Prune trees and shrubs away from your home's exterior to reduce hiding spots for stink bugs.
Summer Monitor your home's exterior for signs of stink bugs and seal any new entry points that may have formed.
Fall Inspect your home's exterior for gaps and cracks, and seal them to prevent stink bugs from entering. Consider using outdoor lighting with yellow bulbs, as stink bugs are less attracted to this color.
Winter Keep indoor plants indoors and away from windows to reduce the attraction of stink bugs. Monitor your home's interior for signs of stink bugs and remove them promptly.

By understanding why stink bugs are invading your home and taking proactive measures to prevent and control these pests, you can create a stink bug-free living environment. Regular inspections, sealing entry points, and reducing attractants are key strategies in managing stink bug infestations. If necessary, consult a professional pest control service for expert assistance in controlling and preventing stink bugs in your home.
