November Alert: Rodents and Fall Invaders in Kansas City

November brings cooler days and shorter sunlight — and with that change, pests start looking for warm, quiet places to overwinter. In the Kansas City area that usually means more mice and rats trying to slip into basements, wall voids, and attics, while fall invaders like boxelder bugs and brown marmorated stink bugs gather on sunny walls looking for entry points. Below is what to watch for, simple steps you can take now, and when to call Rock Pest for help.

Common November pests around Kansas City

Rodents (mice & rats)
Signs: droppings in cupboards, gnawed cardboard or plastic, shredded nesting material (paper, fabric), grease/smudge marks along baseboards, scratching or scampering sounds at night. Why it matters: rodents chew wiring, contaminate stored food, and can cause costly property damage if allowed to nest.
Quick prevention: remove food sources (store food in sealed containers), keep pet food inside or tightly sealed, and keep clutter to a minimum. For heavy activity or obvious entry points, schedule an inspection with Rock Pest’s residential team.

Boxelder bugs & brown marmorated stink bugs
What you’ll see: groups of these insects clustering on the sunny side of buildings, doorframes, or window trim. They’re mostly a nuisance — but when crushed they can stain or give off an unpleasant smell. These bugs often spend the winter tucked into cracks and crevices around exterior siding, window frames, and soffits.
Prevention: seal gaps around windows and doors, repair torn screens, and reduce exterior lighting at night that attracts other insects (spiders feed on these and bring more activity inside). If numbers are large, an exterior inspection/treatment can significantly reduce indoor incursions. (See our residential services above.)

Spiders & cluster flies
Why they show up: as insects gather on warm walls or in attics, spiders follow — and cluster flies specifically seek attic and wall voids to overwinter. Cluster fly numbers can lead to dead flies inside and noticeable clusters in attics and around windows in winter. Heavy spider activity can indicate other insect populations on your property.
What to do: remove webs, seal attic vents and gaps, and reduce insect-attracting lights. For persistent problems, a professional inspection helps locate entry areas and implement long-lasting exclusion work.

Practical prevention checklist (what you can do this weekend)

• Inspect your home’s exterior for gaps around pipes, vents, foundation cracks, and attic openings; seal or note for professional exclusion.
  
• Store pantry items, pet food, and bird seed in sealed, durable containers.
  
• Move firewood and debris away from the foundation; stack wood off the ground.
  
• Repair or replace torn window/door screens and add door sweeps where needed.
  
• Keep outdoor lights to a minimum or switch to yellow “bug” bulbs to reduce insect attraction.
  
• Clean up fallen fruit, overripe veggies, and other yard attractants.
