How to Get Rid of Cockroaches: Killers and Traps That Actually Work

The most effective way to get rid of cockroaches is gel bait placed where roaches travel, backed up by sanitation, moisture control, and sealing entry points. Gel baits work because roaches eat the bait, return to the harborage, and spread it through the population. Sprays kill what you see but rarely reach the nest — which is why roaches keep coming back.

Florida's heat and humidity make it one of the worst states for cockroaches. Here's what actually works.

Treatment depends on the species:

German cockroaches are a different challenge entirely — see why German roaches are so hard to eliminate.

What actually works (in order)

1. Gel bait (the workhorse)

Apply small dabs of cockroach gel bait in cracks and crevices, under sinks, behind appliances, and along hinges — where roaches hide, not out in the open. Roaches feed and carry the active ingredient back to others. Reapply as it's consumed.

2. Insect growth regulators (IGRs)

IGRs stop young roaches from maturing and reproducing, breaking the breeding cycle. Paired with bait, they're highly effective on stubborn infestations.

3. Bait stations and traps

Enclosed bait stations work well in homes with kids or pets. Sticky monitoring traps help you find harborage areas and gauge whether treatment is working.

4. Boric acid (used correctly)

A light dusting of boric acid in wall voids and under appliances can be effective — but too much repels roaches, and it must be kept away from food and pets.

What to skip

• Foggers/"bug bombs" — they scatter roaches deeper into walls and rarely reach the harborage.
• Spray-only approaches — they kill visible roaches but miss the population.

Sanitation and exclusion (this is what keeps them gone)

Roaches need food, water, and shelter. Take them away:

• Clean thoroughly — no crumbs, grease, or dirty dishes overnight; secure food and pet food in sealed containers.
• Fix moisture — repair leaks, dry sinks and tubs, run bathroom fans. Roaches can't last long without water.
• Declutter — remove cardboard and paper piles that make ideal harborage.
• Seal entry points — caulk cracks, screen vents, and seal gaps around pipes and drains (a common palmetto-bug entry).

When to call a professional

If roaches keep returning, you see them in daylight, or you're battling German roaches, it's time for professional help. Pros use targeted baiting, IGRs, and crack-and-crevice treatment that reach the harborage. Our residential pest control in Orlando keeps roaches out year-round.

Frequently Asked Questions

What kills cockroaches the fastest?

Contact sprays kill individual roaches on sight, but gel bait eliminates the population fastest overall because roaches carry it back to the nest. For lasting results, combine bait with sanitation and sealing.

Why do I keep getting palmetto bugs?

American cockroaches (palmetto bugs) usually come in from outside through drains, gaps around pipes, and door gaps, especially in Florida's humidity. Sealing entry points and reducing moisture is key to stopping them.

Do foggers get rid of roaches?

No. Foggers rarely reach the cracks and voids where roaches harbor and can scatter them deeper into the home. Targeted gel baiting is far more effective.

Are cockroaches a health risk?

Yes. Cockroaches can contaminate food and surfaces and are a known trigger for asthma and allergies, especially in children — another reason to eliminate them promptly.
