Whether you’re dealing with creepy crawlers in the basement or winged intruders in the kitchen, pests can quickly turn your cozy home into an unwelcome habitat. Knowing which pests are most common—and how to keep them out—is the first step to protecting your space. Here’s your guide to the top five household pests and simple prevention tips to keep them away.

1. Ants

Why They’re a Problem: Ants are small but persistent. Once they find a food source, they bring the whole colony with them.

Prevention Tips:

Seal Entry Points: Check for tiny cracks in windows, baseboards, and doors.

Keep It Clean: Wipe up crumbs and spills immediately, especially in the kitchen.

Store Food Properly: Use sealed containers for pantry items, and take out the trash regularly.

2. Mice

Why They’re a Problem: Mice can squeeze through openings the size of a dime and bring with them health risks like Salmonella and Hantavirus.

Prevention Tips:

Eliminate Food Sources: Don’t leave pet food or snacks out overnight.

Declutter: Store boxes off the floor and reduce nesting spots in attics or garages.

Seal Gaps: Use steel wool or caulk to seal small holes around pipes and vents.

3. Cockroaches

Why They’re a Problem: Roaches thrive in warm, moist environments and can contaminate food while triggering allergies and asthma.

Prevention Tips:

Fix Leaks: Address any plumbing issues or moisture buildup in kitchens and bathrooms.

Nightly Cleaning: Clean floors and counters thoroughly before bed.

Avoid Cardboard Storage: Roaches love cardboard. Use plastic bins instead.

4. Spiders

Why They’re a Problem: While most spiders are harmless, some (like the brown recluse) can pose a threat. Even harmless ones aren’t welcome guests.

Prevention Tips:

Reduce Clutter: Spiders hide in dark, undisturbed places like basements and closets.

Turn Off Outdoor Lights: Lights attract insects, and insects attract spiders.

Seal Windows & Screens: Prevent easy indoor access by fixing gaps or tears.

5. Termites

Why They’re a Problem: Termites can silently destroy the structure of your home, causing thousands in damage before they’re even discovered.

Prevention Tips:

Limit Wood Contact: Keep firewood, mulch, or wood piles at least 20 feet away from your house.

Control Moisture: Use dehumidifiers in crawl spaces and fix roof or gutter leaks promptly.

Schedule Inspections: Annual termite inspections are critical for early detection.

A pest-free home starts with prevention. By staying vigilant and addressing small issues before they become infestations, you can keep your living space safe and comfortable. Need help tackling a pest problem? Hennebry Pest Solutions is just a call away.
