If you've lived in Indianapolis for any length of time, you've probably seen them — slow-moving, shield-shaped insects crawling on your window sills or fluttering awkwardly around your lights. They’re called stink bugs, and yes, they are common pests in central Indiana.
These insects get their name from the foul odor they release when threatened or crushed, and while they don’t pose a direct threat to humans, they can quickly become a major nuisance inside and outside your home. Let’s take a closer look at why stink bugs are so prevalent in the Indianapolis area and what homeowners can do to keep them at bay.
What Are Stink Bugs?
The most common type of stink bug found in Indiana is the brown marmorated stink bug (BMSB), an invasive species originally from Asia. They were first identified in the U.S. in the 1990s and have since spread across the country. These pests are about the size of a dime, with brownish-gray coloring and a distinctive shield-shaped body.
They’re mostly active during warmer months, but as temperatures drop, stink bugs begin seeking warmth and shelter—often inside Indiana homes. That’s when the real problems begin.
Why Are Stink Bugs So Common in Indianapolis?
Several factors contribute to the widespread presence of stink bugs in Indianapolis:
Indianapolis has a temperate climate with four distinct seasons. The cold winters drive stink bugs indoors, while the warm springs and summers support their breeding and feeding cycles.
Stink bugs feed on a wide variety of fruits, vegetables, and ornamental plants. Since Indiana is a strong agricultural state, the surrounding environment provides a rich food source for these pests, allowing their populations to thrive.
Because they have few natural predators in the U.S., stink bugs multiply quickly and establish large colonies. Once they find a safe place to overwinter—like the attic or walls of your home—they often return year after year.
Are Stink Bugs Dangerous?
Stink bugs don’t bite, sting, or carry diseases that affect humans or pets, which often makes people underestimate the problems they can cause. However, their presence in the home can still be unpleasant for several reasons:
- Odor: Their signature smell, a pungent chemical defense, is released when they’re threatened, squashed, or handled roughly. This can linger in carpets, curtains, and furniture.
- Infestations: While one or two stink bugs might not seem like a big deal, it’s rarely just a few. Where there’s one, there are likely dozens more hiding in walls, vents, or attic spaces.
- Crop Damage: If you have a garden, stink bugs can ruin your vegetables and fruit before you ever get to harvest them. They pierce plant skins to suck out juices, leaving behind unsightly scars and rot.
- Indoor Nuisance: These pests are attracted to light and warmth, so it’s not uncommon to find them crawling on walls, buzzing around lamps, or falling into your drinks.
How Do Stink Bugs Get Inside?
As fall approaches, stink bugs look for warm places to hibernate. They typically enter homes through:
- Cracks around windows and doors
- Gaps in siding or soffits
- Attic vents
- Chimneys
- Basement foundations
Once inside, they’ll settle in wall voids, attics, and crawl spaces until spring, when they become active again—often emerging in large numbers indoors.
What Can Indianapolis Homeowners Do About Stink Bugs?
There are a few steps you can take to reduce your chances of a stink bug infestation:
Inspect your home for cracks, gaps, and loose-fitting windows or doors. Use caulk, weatherstripping, and mesh screens to block entry points.
Keep outdoor lights to a minimum during peak stink bug season, as they’re drawn to light. Also, consider removing or relocating plants close to your home's foundation.
If you find stink bugs indoors, use a vacuum to remove them and immediately dispose of the vacuum bag to avoid spreading the smell. Avoid crushing them at all costs.
