Winter Pest Control Guide

Pest activity doesn't stop in winter β€” it moves indoors. Mice, cockroaches, and rats often have their worst indoor pressure during winter months.

πŸ› Most Active Pests This Season

🐭
Mice
Peak indoor pressure from October through April. New exclusion and trap work most effective.
πŸͺ³
Cockroaches
Year-round in heated structures. Winter is excellent for treatment β€” no competing outdoor harborage.
πŸ€
Norway Rats
Concentrate near heat sources in winter. Bait stations most effective in cold months.
πŸ•·οΈ
Cellar Spiders
Continue hunting other insects in basements. Presence confirms prey insects are also present.
πŸͺ°
Cluster Flies
Emerge on warm winter days confused by indoor heat. Vacuum; don't crush.

πŸ”§ Action Checklist

  • December: Set snap traps along any active rodent run marks. Refresh cockroach gel bait β€” heat from holiday cooking increases activity.
  • January: Check bait stations after temperature drops β€” rodent activity at stations increases in cold weather.
  • February: Begin planning spring termite inspection. March is peak swarm season β€” schedule now.
