How to Get Rid of Stink Bugs in the House in Fall Without the Smell

The best way to get rid of stink bugs indoors without making the smell worse is to never crush them. Pick them up with a vacuum or sweep them into a container of soapy water, then seal the gaps they used to get inside. Stink bugs release their odor when they are squashed or feel threatened, so gentle removal and prevention work better than swatting.

Why stink bugs come inside in fall

Stink bugs are not looking for food or to damage your home. As temperatures drop in autumn, they look for sheltered places to spend the winter. Warm, sunlit walls, cracks around windows, and gaps in siding or roofing attract them. Once inside, they hide in attics, wall voids and cluttered storage, and often become active again on warm days or when the heating comes on.

They do not bite, sting or breed indoors, and they do not harm the structure of your house. The main problem is the odor and the nuisance of large numbers.

Remove stink bugs without the smell

Choose a method that avoids crushing or startling the bugs.

Soapy water jar. Fill a wide jar or bucket with water and a squirt of dish soap. Hold it under the bug and tap it in, or use a piece of paper to guide it. The soap makes it sink and drown.
Gloved hand or paper towel. Wear a glove or use a wad of tissue to pick one up gently, then drop it into the soapy water. Avoid squeezing it.
Vacuum with a stocking trap. Place a nylon stocking over the end of the hose, secured with a rubber band, so the bugs collect in the stocking rather than the vacuum bag. Then take the stocking outside or drop it into soapy water.
Dustpan and bag. Slide a bug onto a dustpan and tip it into a bag you can seal and throw away outdoors.

A standard vacuum can pick up the odor if you suck them straight into the canister, so empty it outdoors afterward and wash any removable parts.

What not to do

Do not crush, squash or flush stink bugs on the spot if you can avoid it. Crushing releases the smell, and the odor can linger on fabric and surfaces.
Do not use aerosol insecticides indoors without careful reading of the label. They are often unnecessary, can irritate people and pets, and are not a lasting fix.
Do not mix cleaning products to remove the smell. Follow label directions and ventilate the room.

If one has already been crushed

Wipe the area with a cloth and warm soapy water. Open windows to ventilate. Wash any fabric that has been affected following the care label. A clean, dry surface with mild soap usually fades the smell faster than strong fragrances do.

Seal the entry points

Prevention is the most reliable long-term fix, and early fall, before the bugs arrive in numbers, is the best time to do it.

Check window and door frames. Seal gaps with exterior-grade caulk. Replace damaged weatherstripping and add door sweeps to the bottom of exterior doors.
Repair screens. Patch holes in window and door screens and make sure they fit tightly.
Cover vents. Fit fine mesh over attic vents, chimney openings and exhaust fans where it is safe and allowed.
Seal utility penetrations. Fill gaps where pipes, cables and wires enter the house with caulk or an appropriate sealant.
Check siding, fascia and trim. Look for cracks and loose boards, especially on the sunny sides of the house.

If you need to work on a roof or at height, hire a professional rather than climbing a ladder alone.

Reduce what attracts them

Turn off outdoor lights when you do not need them, as light can draw insects toward the house.
Clear leaf piles, firewood stacks and clutter next to the walls.
Keep storage areas such as attics and garages tidy so there are fewer hiding spots.
Vacuum regularly to remove bugs that are already overwintering inside.

When to call a professional

If you find dozens of stink bugs inside every day, or they keep returning after you have sealed the obvious gaps, a licensed pest control company can inspect the building and recommend treatment. Ask them to explain the products they use, and tell them about any children or pets in the home.

Quick answers

Do stink bugs bite or cause damage?

No. They do not bite, and they do not damage the house, furniture or food. They are mainly a nuisance because of the smell.

Why do they come back after I remove them?

New bugs can enter through gaps you have not sealed, and others may emerge from wall voids on warm days. Sealing the gaps is what stops this.

Does vacuuming make the house smell?

It can, because the bugs release odor inside the vacuum. Using a stocking trap and emptying it outdoors reduces the problem.

Can I just release them outside?

You can, but they will often try to come back in. Drowning them in soapy water is more reliable.
