Top 10 Household Pests and How to Keep Them Out for Good

Have you ever walked into your kitchen only to find a line of ants marching across your countertop? Or perhaps you’ve settled down for the evening, only to hear the telltale scratching of mice in your walls? If you’ve nodded along to these scenarios, you know just how unsettling it can be to share your home with unwanted guests. Pests can be more than just a nuisance; they can pose health risks and cause damage to your property. Fear not! In this comprehensive guide, we’ll explore the top 10 household pests and provide you with effective strategies to keep them out for good.

Understanding Household Pests

Before diving into our list of pests, it’s important to understand why they invade our homes. Pests are typically attracted to food, shelter, and water. Therefore, maintaining a clean, well-organized home can significantly reduce the likelihood of an infestation. Now, let’s break down the top 10 household pests and how you can prevent them from making themselves at home.


1. Ants

Why They Invade

Ants are social insects that thrive in colonies. They are attracted to food sources, especially sugary substances and scraps that may have been left out.

How to Keep Them Out

  • Seal Entry Points: Inspect your home for cracks and crevices, especially around windows, doors, and the foundation. Use caulk to seal these gaps.
  • Clean Regularly: Wipe down countertops, sweep floors, and store food in airtight containers.
  • Use Natural Repellents: Vinegar, lemon juice, and cinnamon can deter ants. Mix equal parts vinegar and water in a spray bottle and apply it to areas where you see ant activity.

2. Cockroaches

Why They Invade

Cockroaches are nocturnal creatures that love damp, dark environments and are often found in kitchens and bathrooms.

How to Keep Them Out

  • Eliminate Moisture: Fix leaking pipes and eliminate standing water in sinks and bathtubs.
  • Store Food Properly: Keep food in sealed containers and avoid leaving pet food out overnight.
  • Set Traps: Use cockroach baits and traps to monitor and reduce their population.

3. Rodents (Mice and Rats)

Why They Invade

Rodents seek food, warmth, and shelter. They can squeeze through tiny openings and often invade homes in search of these necessities.

How to Keep Them Out

  • Seal Holes and Cracks: Use steel wool and caulk to block potential entry points.
  • Remove Food Sources: Store food in metal or glass containers and keep your kitchen tidy.
  • Use Traps: Snap traps and glue boards can effectively control rodent populations.

4. Termites

Why They Invade

Termites are attracted to wood and cellulose materials. They can cause significant structural damage if left unchecked.

How to Keep Them Out

  • Moisture Control: Repair leaks and ensure proper drainage around your home.
  • Wood Treatment: Use treated wood for construction and maintain a barrier between soil and wood.
  • Regular Inspections: Schedule annual inspections with a pest control professional to catch infestations early.

5. Bed Bugs

Why They Invade

Bed bugs are excellent hitchhikers, often traveling home with luggage, clothing, or used furniture.

How to Keep Them Out

  • Inspect Second-Hand Items: Always check for bed bugs before bringing used furniture or clothing into your home.
  • Wash and Heat-Dry: Launder bedding and clothing in hot water and dry on high heat to kill any hidden bugs.
  • Encase Mattresses: Use bed bug-proof mattress and pillow encasements to prevent infestations.

6. Spiders

Why They Invade

Spiders are generally harmless and often enter homes in search of food (insects) and shelter.

How to Keep Them Out

  • Reduce Clutter: Clear out webs and clutter where spiders may hide.
  • Seal Cracks: Like many pests, spiders can enter through small openings. Caulk and seal any cracks.
  • Natural Repellents: Essential oils such as peppermint or tea tree oil can deter spiders when mixed with water and sprayed around the home.

7. Flies

Why They Invade

Flies are drawn to food, garbage, and waste. They can quickly become a problem in the warmer months.

How to Keep Them Out

  • Keep Food Covered: Always cover food and clean up spills immediately.
  • Dispose of Waste Properly: Use tightly sealed trash cans and take out the garbage regularly.
  • Install Screens: Use window and door screens to block flies from entering.

8. Silverfish

Why They Invade

Silverfish thrive in damp, dark areas and are often found in bathrooms, basements, or kitchens.

How to Keep Them Out

  • Reduce Humidity: Use dehumidifiers in damp areas of your home.
  • Store Paper Properly: Keep books and papers in sealed containers to prevent silverfish from accessing them.
  • Regular Cleaning: Vacuum regularly to eliminate eggs and prevent infestations.

9. Wasps and Hornets

Why They Invade

Wasps and hornets build nests in sheltered areas and are attracted to food and sweet drinks during summer.

How to Keep Them Out

  • Remove Nests: Identify and remove nests in early spring before they become active.
  • Keep Food Covered: When eating outdoors, keep food and drinks tightly sealed.
  • Seal Entry Points: Just like with other pests, sealing cracks and holes can prevent wasps from entering your home.

10. Fleas

Why They Invade

Fleas often come from pets or other animals and can quickly infest your home.

How to Keep Them Out

  • Regular Pet Care: Treat pets with flea prevention products and bathe them regularly.
  • Vacuum Frequently: Vacuum carpets, rugs, and upholstery to remove flea eggs and larvae.
  • Wash Bedding: Regularly wash pet bedding and your own bedding in hot water.
