Lebanon’s Fall Challenge: Pests Seeking Shelter

As fall settles over the Ozarks, overwintering pests start looking for protected places to ride out the cold months. Homes in Lebanon often become targets for these invaders — especially older structures or houses surrounded by trees and fields. Small openings around siding, vents, and door frames can quickly turn into pest gateways. By spending a weekend sealing those entry points, homeowners can stop unwanted guests before winter even starts.

Typical Overwintering Pests in Lebanon Homes

  • Brown Recluse & Black Widow Spiders – These spiders prefer dark storage areas and basements.
  • Asian Lady Beetles & Stink Bugs – Found clustering on sunny exterior walls before slipping inside.
  • Boxelder Bugs – Enter through cracks near windows and foundations.
  • Mice & Rats – Squeeze through holes as small as a dime, nesting in garages and attics.

Once inside, these pests stay hidden until spring, often causing damage or leaving behind unpleasant odors and droppings.

Your Seal-Up Weekend Plan

  1. Inspect Around Windows & Doors: Replace cracked caulking or worn weatherstripping.
  2. Seal Utility Openings: Close gaps where pipes, cables, or vents enter the home.
  3. Add Door Sweeps: Prevent rodents and insects from crawling underneath entryways.
  4. Check the Attic & Crawl Space: Look for gaps around vents or eaves.
  5. Trim Vegetation: Keep shrubs and firewood several feet from your foundation to limit pest access.
  6. Schedule a Professional Perimeter Treatment: A local pest control expert can identify problem areas and apply a protective barrier.
