What Do Stink Bugs Eat? And Why They Might Be Hanging Around Your Home

You’ve seen them on your windows. Maybe one buzzed past your ear or showed up on the ceiling out of nowhere. They’re harmless if you leave them alone, but if you squish one, well, you know why they’re called stink bugs.

They show up every fall, crawling around like they own the place. But what do stink bugs eat, and why are they trying to move into your home?

Let’s break it down so you know what you’re dealing with and when it might be time to call an insect exterminator near you.

 

What Do Stink Bugs Eat?

In their natural habitat, stink bugs feed on plants. They’re not hunters or scavengers, and they’re definitely not after your pantry food. They use their straw-like mouthparts to suck the juices from:

• Fruits like apples, peaches, and pears
• Vegetables such as tomatoes, peppers, beans, and corn
• Ornamental plants and flowers
• Crop plants like soybeans (especially in rural parts of Wisconsin)

They can cause real damage in gardens or farms, but inside your house, they’re more of an annoyance than a threat. They don’t bite, chew, or damage furniture but they’re still not welcome guests.

 

Why They Come Inside

It all comes down to one thing: warmth.
When the air turns chilly in fall, stink bugs start searching for a sheltered spot to wait out the cold. A house with steady heat, dry corners, and peace and quiet is perfect for them.

They usually find their way in through small openings such as:

• Loose window or door frames
• Cracks in the siding or foundation
• Gaps around attic vents or crawl spaces
• Openings near exhaust fans or outdoor outlets

Once one sneaks in, others tend to follow the same path.

 

How to Keep Stink Bugs Away

If you’re only spotting one or two, you can often stay ahead of them with a bit of prevention. Here’s what helps:

• Seal up gaps around windows, doors, and utility lines
• Repair or replace torn window screens
• Spray a light mix of garlic water around common entry points
• Vacuum any that get inside instead of squishing them (to avoid the smell)
• Keep outside lights low at night since bright lights draw them in

These steps won’t wipe them out completely, but they’ll make your home far less appealing to them.

 

When It’s Time to Call a Local Insect Exterminator

At first, a few stink bugs might not seem like a big deal. But when you start finding them in the attic, basement, or even crawling out of vents, it’s time to call a professional.

Reach out to an insect exterminator near you in Wisconsin if:

• You’re seeing them day after day
• They’ve started showing up in bedrooms or closets
• You’ve sealed cracks, yet they keep coming back
• You want to stop another invasion before next season

A licensed pest technician can locate and treat the entry points more effectively than store-bought sprays. They also know the seasonal habits of local bugs. Knowledge that makes a big difference when keeping your home pest-free for good.

A few stink bugs might be tolerable. But when they start showing up every day or crawling around your ceiling like they belong there, it’s time to take action.
