The Basics of Home Pest Control
Bugs and rodents want three things. They want food, water, and shelter. Your house has all three. The secret to good pest control is blocking their access. You can stop most problems before they start by sealing gaps and fixing leaks. Sometimes pests still get inside. When that happens, you need to know exactly what you are dealing with.
Ants: Tiny Invaders with Big Networks
Ants send scouts to find food. If a scout finds a crumb on your floor, it leaves a scent trail for the rest of the colony. To stop ants, you have to break that trail. Wipe down counters with soapy water. Keep dry goods in sealed containers.
For small invasions, liquid ant baits work well. The ants carry the poison back to the nest and share it with the queen. Do not spray trailing ants with bug spray. If you kill the workers, the colony just sends more.
Mice and Rats: Stopping Rodents at the Door
Mice can squeeze through a hole the size of a dime. Rats need a hole the size of a quarter. Walk around your house and look for gaps. Check where pipes enter the house. Seal small holes with steel wool and caulk. Check your exterior siding for loose boards or cracks.
If rodents get inside, snap traps are your best bet. Place them along walls where mice run. Peanut butter makes great bait. Avoid using poison inside your house. A poisoned mouse might die inside your walls. This creates a terrible smell that lasts for weeks.
Termites: The Silent Wood Destroyers
Termites cause billions of dollars in damage every year. They eat wood from the inside out. You might not see them until the damage is done. Look for mud tubes on your foundation walls. These tubes look like thick brown veins. Also look for discarded wings near windows or doors.
If you suspect termites, do not try to fix it yourself. You need a professional. A pro will trench around your house and apply a liquid termiticide. They might also install bait stations in the ground. Inspect your foundation and structure every year to catch signs early.
Wasps and Hornets: Stinging Threats
Wasps build paper nests under eaves, behind shutters, and inside gutters. Yellow jackets often build nests in the ground. If you find a small paper wasp nest early in the summer, you can spray it yourself. Buy a foaming wasp spray that shoots 15 to 20 feet. Always spray at night when the wasps are resting inside the nest.
Average Costs for Pest Control Services
Pest control costs depend on the type of bug and the size of your house. A single visit to spray for spiders or ants usually runs $150 to $300. Termite treatments cost much more. Prices vary by region, home size, and the age of your house.
| Pest Type | Treatment Method | Estimated Cost |
|---|---|---|
| Ants | Baiting and perimeter spray | $150 to $300 |
| Mice | Inspection, trapping, and sealing holes | $250 to $500 |
| Wasps | Nest removal and exterior spray | $150 to $400 |
| Termites | Liquid barrier and bait stations | $1,000 to $3,000 |
If you have a mouse problem, fixing it yourself is cheap. Hiring a pro to do a full exclusion seal on your home costs a lot more but solves the problem for good.
Prevention Tips to Keep Bugs Out
The best pest control is keeping them out in the first place. Follow these simple steps to protect your home.
- Keep mulch and soil at least 6 inches below your siding.
- Trim tree branches so they do not touch your roof. This stops ants and roof rats. Read more about trimming in our landscaping guide.
- Fix leaky outdoor faucets. Bugs need water to survive.
- Store firewood at least 20 feet away from the house.
- Put weather stripping on all exterior doors.
When to Call a Pro vs Doing It Yourself
You can handle a few ants or a stray mouse on your own. Buy traps, clean your kitchen, and seal up holes. But some pests are too risky or too stubborn. Call an exterminator if you see signs of termites, bed bugs, or a massive rat problem. You should also hire a pro if you have tried DIY methods for a month with no luck.
