Winter is Coming, and So Are Wasps!

Winter brings cold, cozy nights by the fireplace and hot cocoa, but it also brings an unwelcome guest: wasps. While these stinging insects are usually associated with the warm months, many people are surprised to find wasps attempting to take refuge inside their homes during the winter season.

Why do wasps invade your home when it's chilly outside, and what can you do to keep them out? This blog will provide you with essential tips and tricks to ensure your home stays wasp-free all winter long.

Why Do Wasps Invade Your Home in Winter?

Wasps are cold-blooded insects, which means their body temperature drops with the outdoor temperature. As the winter chill sets in, they seek warmth and shelter, and your home seems like the perfect place to nestle in.

Here are some common reasons why wasps invade homes in winter:

  • Warmth: Your cozy, heated home is a magnet for wasps seeking to raise their body temperature.

  • Nesting: Some wasp species look for sheltered areas to build their nests, which could include your attic, crawl spaces, or wall voids.

  • Food: Wasps may also be attracted by any remaining food or crumbs in your kitchen.

Now that you understand why wasps might try to invade your home, let's dive into the steps you can take to prevent this winter unwelcome guest.

Tips to Seal Your Home and Keep Wasps Out

  • Seal Cracks and Gaps: Inspect your home for any openings where wasps can enter. Use caulk or weatherstripping to seal cracks in windows, doors, and walls.

  • Install Screens: Make sure your doors and windows have intact screens to prevent wasps from flying in.

  • Keep Trash Bins Sealed: Ensure your outdoor trash bins have tight-fitting lids to avoid attracting wasps with food residue.

  • Use your fireplace: Wasps love to nest in the warmth of your fireplace, so set a fire occasionally to keep them out.

  • Regular Inspections: Periodically inspect your home's exterior and interior to catch any signs of wasp activity early.

Encountering a Wasp Indoors: What to Do

Despite your best efforts, sometimes a wasp might still find its way inside. Here's what to do if you encounter one:

  • Stay Calm: Panic can lead to accidents. Stay calm and move slowly.

  • Don't Swat: Avoid swatting at the wasp, as this can provoke it to sting.

  • Open a Window: If the wasp is near an open window, gently encourage it to fly out by providing an escape route.

  • Use a Container: If it's safe, try trapping the wasp under a glass or container and carefully slide a piece of paper underneath to transport it outside.

  • Call a Professional: If you're uncomfortable dealing with wasps, or if the situation becomes dangerous, it's best to call a pest control expert for safe removal.


As the temperature drops, wasps may seek refuge in your home. By following these tips to seal your home and knowing how to handle an indoor encounter, you can ensure your winter remains sting-free. Enjoy your cozy, pest-free home all season long!
