How to Prevent Wasps from Entering Your Home in Autumn

As autumn arrives, temperatures drop, and wasps start searching for a warm refuge to settle into for the winter months.

Often, your cozy home becomes an attractive destination.

Here’s a guide on how to prevent these unwelcome visitors from entering your space, ensuring a comfortable, wasp-free environment throughout the season.

1. Seal Entry Points

Wasps can find their way indoors through even the smallest openings. Inspect your home’s exterior carefully for potential entry points such as:

  • Gaps around windows and doors: Use weather stripping or caulk to seal any cracks.
  • Vents and exhaust fans: Consider covering these with fine mesh screens to keep wasps out while allowing airflow.
  • Gaps in walls and roof: Check for cracks in the foundation, around the chimney, and other potential gaps.

2. Secure Your Doors and Windows

Ensure all doors and windows close tightly, and that screens are intact. Wasps are skilled at locating weaknesses, so:

  • Install door sweeps on any exterior doors with noticeable gaps.
  • Repair or replace damaged screens on windows, doors, and vents.
  • Use self-closing hinges or springs on frequently-used doors to prevent accidental entry.

3. Avoid Leaving Food and Drinks Out

Wasps are particularly attracted to sweet smells, making uncovered food and drinks a lure. Follow these steps to reduce attraction:

  • Store sugary foods and beverages indoors or in airtight containers.
  • Rinse food and drink containers before placing them in recycling bins.
  • Keep trash bins tightly sealed and regularly clean any spills on or near them.

4. Limit Outdoor Lighting at Night

Outdoor lighting can attract various insects, which in turn attracts wasps. To reduce this effect:

  • Switch to yellow-toned LED lights, which are less attractive to insects.
  • Turn off outdoor lights when they’re not necessary.
  • Close curtains or blinds to keep interior lights from drawing attention to your windows.

5. Set Up Wasp Traps Away from Entry Points

If wasps are already around your property, traps can help reduce their numbers. You can buy wasp traps or make your own by filling a bottle with a sugary solution. Place traps strategically to keep wasps away from your home’s main entry points.

6. Use Natural Repellents

Certain scents act as natural wasp deterrents, including peppermint, citronella, and clove oil. Here’s how to use these effectively:

  • Create a peppermint spray by diluting a few drops of peppermint oil in water and spraying around entry points.
  • Burn citronella candles or incense near outdoor gathering areas.
  • Place cloves or slices of lemon near entry points.

7. Regularly Inspect for Nesting Activity

Wasps often build nests in quiet or hidden areas around homes. By staying vigilant, you can catch early signs of wasp activity before they become problematic. Check:

  • Under eaves, decks, and porches
  • In sheds, garages, or attics
  • In woodpiles, bushes, and trees close to the house

If you spot a nest, avoid disturbing it, as wasps can become aggressive. For safety, call a wasp control professional if the nest is sizable or difficult to access.

8. Keep Your Garden Tidy

Keeping your yard neat minimizes areas where wasps like to nest and gather:

  • Regularly trim hedges and mow the lawn.
  • Clean up fallen fruits and flowers which might attract wasps.
  • Keep compost bins covered to limit food sources.

9. Stay Vigilant and Be Patient

If you’ve had trouble with wasps in past autumn seasons, your vigilance will pay off. Routine inspections and preventive measures are key to minimizing wasp attraction and entry, allowing you to enjoy a warm, worry-free season indoors.

By applying these simple but effective measures, you can create a strong defense against wasps, making your home a far less appealing target as temperatures cool down.
