Cockroaches at home: how to get rid of them and keep them out

Live or dead cockroaches, dark spots or smears, shed skins and egg cases can point to activity. A single insect does not reveal the size of the problem. Note where and when you saw it, then inspect nearby hiding places.

A cockroach seen at home is not automatically an Oriental cockroach. For identification features of one documented species in Georgia, see the Oriental cockroach profile. This guide applies more broadly.

Use a flashlight to look under the sink, in the back of cabinets, along skirting boards and cracks, and behind accessible appliances. Look for moisture and dark marks. Do not dismantle electrical appliances or put chemicals inside them.

Check boxes or stored items before bringing them inside. If you find a repeated trail, note the location so you can target cleaning and monitoring there.

Store food in well-closed containers, clear crumbs and spills, and use a lidded rubbish bin that you empty regularly. Clean behind accessible kitchen appliances and remove unnecessary cardboard and paper piles that offer shelter.

Repair leaking pipes, wipe up pooled water and address persistent dampness. Keep pets' drinking water available; instead, clear spilled water and leftover food around their bowls. Seal gaps around pipes, cabinets, doors and skirting boards where cockroaches may enter or hide.

A sticky trap catches insects for detection and monitoring. Place it along a wall near suspected hiding places, away from children and pets. Check traps regularly and compare which locations catch insects before and after your changes.

An insecticide bait contains a pesticide that a cockroach eats. It serves a different purpose. A sticky trap alone does not promise complete removal; persistent catches mean you should look again for food, water, hiding places or entry gaps.

A cockroach bait station or gel may help when activity is established, alongside cleaning and sealing. Baits work gradually and may take a week or longer to show a reduction. Results depend on the situation; do not expect an overnight fix.

Choose a product labeled for cockroaches and the intended indoor location. Follow its instructions and warnings for placement and repeat use. Never increase the dose on your own. Keep bait, gel and packaging out of children's and pets' reach; a closed station does not remove every risk. Store products in their original containers. Do not use an outdoor-only product indoors.

Do not spray the whole room at random. Sprays alone do not give lasting control and may scatter cockroaches into other areas. Total-release aerosol foggers, or “bug bombs,” often miss their hiding cracks; their flammable contents and pesticide exposure create additional risks.

Do not mix chemicals or make food-based poison recipes. Do not put pesticides into electrical equipment or spread poisonous powders on surfaces people and pets can touch. A “natural” label is not proof of safety or effectiveness.

Get help when activity is heavy, hard to locate or keeps returning despite cleaning, sealing and monitoring. Ask the professional to find and correct the sources of food, water and entry, explain the chosen treatment, and identify the product used. There is no single number of sightings that sets a threshold for every home.

These steps reduce the conditions that help cockroaches persist. They cannot guarantee that none will ever return.

• Keep food covered, crumbs cleared and rubbish closed.
• Fix leaks and clear spills while keeping pets' drinking water available.
• Remove excess cardboard, seal gaps and check incoming boxes.
• Recheck sticky traps; if activity rises again, look for a missed source or ask for help.
