Common household pests, such as ants and cockroaches, along with rodents need the same things humans need to survive. That is, they need food, water, and a place to live. Unfortunately, your house provides them the same essentials that you need. If you can eliminate their access to any of those essential elements, it will help in controlling the pest.
Indoor pest prevention tips
Outside doors must be well sealed. If light can be seen around or under a door, then insects can enter your home.
Keep AC filters clean & thermostats properly adjusted so that mold and mildew build-up does not attract tiny insects.
Empty trashcans regularly and clean up crumbs and spills that would attract bugs and rodents.
Outdoor pest prevention tips
Repair torn screens anywhere on your property to prevent insect entry.
Seal around soffits and gable vents to ensure rodents and insects can't gain access to your attic.
