Why Most DIY Pest Control Doesn't Work
Most people reach for a spray can when they spot a pest. It's the most common DIY response — and one of the least effective. Here's why home pest control often fails, and what actually works instead.
Mistake 1: Using Sprays on Cockroaches
Surface sprays kill on contact but don't reach the nest. Cockroaches quickly learn to avoid treated areas, and the colony continues to grow. The only method that reaches the whole colony is gel bait, which cockroaches carry back and share. Read more: Why Sprays Don't Kill Cockroaches.
Mistake 2: Using Poison for Mice
Rodenticide is dangerous for children, pets, and wildlife. Poisoned mice often die inside walls, causing odors and attracting secondary pests. Non-toxic alternatives are just as effective. See How to Get Rid of Mice Without Poison.
Mistake 3: Ignoring Entry Points
Treating pests without sealing their entry routes means re-infestation is inevitable. Always inspect and seal gaps around pipes, doors, and foundations before or during treatment. Read How to Pest-Proof Your Home for a full checklist.
Mistake 4: Inconsistent Treatment
One application is rarely enough. Pest control requires consistent, repeated treatment over 2–4 weeks to break the breeding cycle. Sticky traps should be checked and replaced regularly.
What Actually Works
For cockroaches: Use Sulguy Cockroach Gel Bait in cracks and crevices near hiding spots. Combine with Sulguy Glue Traps to monitor activity.
For ants: Seal entry points and apply Sulguy Peppermint Spray along baseboards. See The Complete Guide to Ant Control.
For mice: Place Sulguy Sticky Mouse Traps along walls and seal all entry points. Apply Sulguy Diatomaceous Earth around entry points as a deterrent.
The Bottom Line
DIY pest control works — but only when you use the right products consistently and address the root cause. Targeted, non-toxic solutions outperform generic sprays every time.
