How To Get Rid of Cockroaches in Your Home

Cockroaches are one of the most common household pests, known for their ability to survive and multiply rapidly.

While they don’t directly cause serious health issues, they can spread bacteria and trigger allergies and asthma. Getting rid of cockroaches requires patience and diligence, as they can be difficult to fully eliminate. However, with the right techniques and products, you can significantly reduce or even eradicate a cockroach infestation in your home.

Identify Potential Entry Points

The first step is finding out how and where cockroaches are getting into your home. Check for cracks and crevices along baseboards, under sinks, around pipes, windows, doors, and in the attic and basement. Cockroaches can squeeze into spaces as small as 1/16 of an inch. Seal these entry points with caulk or weather stripping to block access into your home. Pay close attention to areas where food, water, and warmth are easily accessible, as these are prime locations cockroaches seek out.

Sanitation and Cleaning

Cockroaches thrive in dirty conditions, so general cleaning and sanitation will help reduce their food sources. Sweep and mop floors, clean countertops, empty garbage frequently, fix leaky pipes and drains, and don’t leave out food or dirty dishes overnight. Vacuum frequently to remove food crumbs and debris that attract cockroaches. Be sure to clean less accessible spots like underneath major appliances and inside cabinets. Any standing water, grease, or food remnants can sustain cockroaches.


Using cockroach traps is an effective way to catch and kill roaches while monitoring the extent of the infestation. Sticky traps use glue to immobilize cockroaches that make contact. Bait traps use food or pheromones to lure cockroaches in before trapping them. Place traps along walls, under appliances, under sinks, and anywhere else you see signs of cockroaches. Check traps frequently to dispose of caught roaches. Replace bait and sticky substance regularly for maximum effectiveness. Traps can provide an indication of the size of the infestation and if your treatment methods are working.

Insect Growth Regulators

Insect growth regulators (IGRs) are chemical products that interfere with a cockroach’s development and ability to reproduce. IGRs come as sprays, gels, or bait additives that can be applied to cockroach hiding spots. The effects target young and juvenile cockroaches, preventing them from reaching adulthood and multiplying. IGR treatments need to be reapplied periodically. They are less toxic to humans compared to traditional pesticides.

Boric Acid

Boric acid is one of the most common and proven home remedies for cockroaches. It’s a powder that can be sprinkled around hidden cockroach harborages. Cockroaches walk through the powder, which sticks to their bodies. When grooming themselves, they ingest the boric acid, causing dehydration and eventual death. The powder also abrades their exoskeleton. Apply boric acid into cracks and crevices out of reach of children and pets. While not immediately lethal, boric acid repeatedly weakens cockroaches over several days. Reapply after vacuuming or if rain gets the powder wet.

Diatomaceous Earth

Diatomaceous earth is made from fossilized remains of diatoms, a type of hard-shelled algae. It comes as a dust that can be sprinkled in cockroach hideouts. The powder is abrasive and absorbs oils and fats from the cockroach’s exoskeleton, leading to dehydration. Diatomaceous earth can persist longer than boric acid powder. Use food-grade diatomaceous earth in areas away from children and pets. Wear a mask when applying to avoid inhaling it.

Essential Oils

Natural essential oils like peppermint, tea tree, and eucalyptus have insecticidal properties. Try soaking cotton balls in these oils and leaving them in cockroach hotspots. The potent aromas can repel and even kill cockroaches. You can also mix the oils with water in a spray bottle. Some oils like bay, clove, and lemongrass oil are specifically effective against cockroaches. Maintain safety around children and pets, as the oils can irritate skin and respiratory systems in high concentrations. Test oils in an inconspicuous area first to check for discoloration or damage.

Insecticide Sprays and Dusts

For more severe cockroach infestations, you may need stronger chemical pesticides applied by a professional exterminator. Insecticide sprays, foggers, and dusts contain chemicals like pyrethroids that immediately kill cockroaches on contact. Professional treatments reach cracks, voids, attics, vents, and other areas you can’t easily access at home. Strictly follow label instructions and safety precautions when using cockroach insecticides. Avoid overusing chemical pesticides, as cockroaches can develop a resistance. Only use indoor chemicals formulated specifically for cockroaches.

Prevent Cockroach Re-infestation

After addressing an existing cockroach infestation, take steps to prevent the pests from recurring. Continue sanitation and cleaning habits like washing dishes immediately after use, cleaning up spills quickly, and taking out the garbage every night. Keep food sealed tightly, especially sugars, grains, and cereals that attract cockroaches. Fix any remaining leaks or drips. Inspect regularly for signs of re-infestation like droppings or egg casings. Immediately treat any cockroaches you spot with targeted methods. Stopping re-infestation before it spreads is crucial for long-term cockroach elimination.

Adopting diligent, regular effort using multiple control methods gives the best chance of kicking out your cockroach problem for good. Traps and monitors help gauge infestation levels while powders, gels, essential oils, and insecticides kill them on contact. Maintaining cleanliness and sealing entry points removes the fundamental conditions that attracted cockroaches in the first place. With persistent cockroach prevention habits, you can successfully evict these invasive pests from your home for a roach-free environment.
