I had a serious ant problem two years ago. I tried everything — sprays, traps, you name it. Most of it was a waste of money. After a lot of trial and error (and one call to a pest control pro who told me his actual secrets), I found the products that genuinely work. Here are the 6 I recommend to everyone.

The #1 Rule of DIY Pest Control

Before I get to products, here is the most important thing I can tell you: pest control is about breaking the breeding cycle, not just killing the bugs you see. The ants marching across your kitchen counter represent maybe 5% of the colony. The other 95% are in the walls, under the foundation, or in the yard. Products that kill on contact are satisfying but ineffective long-term. You need bait products that worker insects carry back to the colony. That is how you actually solve the problem.

1. TERRO T300B Liquid Ant Bait — The Best Ant Product Period

TERRO is the product I have recommended for years and it is still the best ant bait available. The borax-based liquid bait is carried back to the colony by worker ants, killing the queen and the entire nest within days. The pre-filled bait stations are clean and easy to place. You will see more ants at first — that means it is working. Do not spray anything near the bait stations or you will interrupt the process. Give it 3-5 days and the problem will be gone. I have used this three times now and it has worked every single time.

Pest problems are stressful, but they are solvable with the right products and a little patience. Start with TERRO for ants, Ortho for perimeter defense, and Combat Max for roaches — those three products cover 90% of common household pest problems. The key is using bait products that work on the whole colony, not just the bugs you can see.

Frequently Asked Questions

What is the fastest way to get rid of ants?

TERRO liquid ant bait is the fastest and most effective method. It works by letting worker ants carry the bait back to the colony, killing the queen within 3-5 days. Resist the urge to spray — it kills the workers before they can deliver the bait and makes the problem worse.

Are DIY pest control products as effective as professional treatments?

For most common household pests — ants, roaches, mice, wasps — yes. The products professionals use are often the same ones available to consumers. The difference is knowledge of application technique, which is why I covered placement tips for each product above. For serious infestations (termites, bed bugs, large rodent colonies), call a professional.

How often should I apply Ortho Home Defense?

Ortho recommends reapplication every 12 months indoors and every 3 months outdoors. I apply it every spring indoors and after heavy rain outdoors. If you see new pest activity, reapply to the affected areas immediately.
