As the winter months approach, mice and other rodents often seek shelter in warm and cozy homes, making it essential for Middletown homeowners to take proactive measures to prevent infestations. At First State Defense, our team of expert pest control professionals has compiled a comprehensive guide on how to stop mice from entering your house in the winter.

Seal All Entry Points

Mice can squeeze through tiny openings, so it's crucial to seal all cracks and crevices around your home, including holes around pipes, vents, and doors. Our Carpenter Bees Exterminator service can also help identify and seal entry points used by other pests. Additionally, consider installing door sweeps or weatherstripping to prevent mice from entering under doors.

Common Entry Points

  • Around pipes and faucets
  • Vents and chimneys
  • Doors and windows
  • Holes around electrical outlets

Keep Your Home Clean and Clutter-Free

Mice are attracted to food and clutter, so keeping your home clean and organized can help deter them. Store food in sealed containers, clean up crumbs and spills promptly, and avoid cluttering your home with boxes and paper products. Our Roach Exterminator service can also help eliminate other pests that thrive in cluttered environments.

Additional Tips

  • Store firewood and other materials away from your home
  • Keep your yard clean and free of debris
  • Consider using humane mouse traps or repellents
