Why Stink Bugs Are In Your House
                     Why Are 
Stink Bugs
In Your House 
Stink bugs are fairly non-threatening to 
humans, but they are still an insect you 
don’t want in your house. 
As their name suggests, their main defense 
mechanism is to release an odorous fluid 
if they feel threatened.

If you come in contact with this liquid, 
it can cause skin irritation. 
Some people also may experience 
allergic reactions to the scent that 
stink bugs release.

Figuring out why these bugs 
are in your house helps you 
to stop this common and 
annoying pest problem.
Why Are Stink Bugs 
Suddenly Showing Up?
A stink bug’s life cycle involves mating and reproducing 
throughout the spring and summer months. 
Once winter comes along, they seek out shelter from 
the cold and go dormant. 
If you’ve suddenly noticed a large amount 
of stink bugs, then you’ve likely caught 
them at a critical point in their seasonal 
behaviors. 
Whether they are reproducing or seeking 
a winter shelter, watching out for these 
reasons why they are in your house helps 
you create an action plan to stop the invasion.
They’ve Found 
an Easy Entry Point
Like many other pests, stink bugs need 
a way to get inside to start an infestation. 
Look around your house for these 
common points of entry.
• Holes in window screens
• Broken weatherstripping around windows 
and doors
• Cracks around electrical outlets and pipes
• Damaged siding or cracks around the 
foundation
They’re Attracted 
to Your Home’s Lighting
These insects are attracted to lights. 
Consider switching to motion-activated 
lights to illuminate your home’s pathways 
in the evenings.

Switching to yellow bulbs or sodium vapor 
lights can also help you to avoid attracting 
stink bugs to the door.
They Hitched a Ride On 
Something You Carried Inside
If you’ve recently done work on the outside 
of your house, then it is possible that you 
brought stink bugs inside with you. 
This commonly happens when someone 
brings in outdoor seasonal decorations that 
are infested with stink bugs. 
Giving inflatables, flags and other items 
a shake before bringing them in for 
storage helps to keep bugs outside 
where they belong.
They’re Living Somewhere 
Close to Your Home
Stink bugs feed on many different types 
of plants and they’ll follow the crop season. 
At first, they’ll spend time on grass 
and weeds. 
Once fruit trees and vegetable plants start 
to grow, then they’ll head there. 
Try to keep your lawn weed-free and the 
grass short. 
This deters them from showing up 
in the first place. 
Keeping gardening areas as far from 
your home’s exterior walls as possible also 
helps to keep them from coming inside.
How Do You Get Rid 
of a Stink Bug Infestation?
Right now, you might be wondering how to 
immediately address a stink bug problem. 
First, you’ll want to avoid squishing 
these bugs. 
The scent that they release is pungent 
and it can linger for hours. 
Instead, you can vacuum them up. 
Just make sure to dispose of the vacuum bag 
immediately to avoid lingering smells.
Some people also have success with 
trapping stink bugs in a dish of soapy water. 
If you have a large number of stink bugs, 
then insecticidal sprays make the 
elimination process easier and faster.
