How to get rid of and exterminate cockroaches

If you’ve spotted cockroaches in your home or business, you’ll want to know how to get rid of cockroaches. Often, the first step people take is to try DIY methods. These might help reduce activity for a short time, but they rarely solve the full problem or address the root cause of an infestation. Our professionals can help identify what is attracting these pests, how they’re getting indoors, and build a treatment plan to help reduce roach activity and prevent them from coming back. Here's a look at how we approach roach control.

Understanding types of cockroaches

Cockroach species vary in size, color, and behavior. Knowing which type you’re dealing with can help you determine how to get rid of roaches. The most commonly found species in the United States are highlighted below. However, you may still encounter species like wood cockroaches (Parcoblatta spp.) and smoky brown cockroaches (Periplaneta fuliginosa), which are typically found outdoors near woodpiles and can enter buildings through gaps or vents.

Below are four of the most common species found in homes and businesses.

German cockroach

The German cockroach (Blattella germanica) is one of the most common indoor species. These roaches prefer warm, humid spaces close to food and moisture, such as kitchens and bathrooms. A roach infestation involving this species can grow quickly if not addressed.

Oriental cockroach

Oriental cockroaches (Blatta orientalis) tend to live in damp, dark areas like basements or crawl spaces. They’re slower-moving and can be harder to detect until the infestation becomes visible. Watch for them near leaky pipes or drains.

American cockroach

The American cockroach (Periplaneta americana) is large in size and often found in sewers or basements. The American roach is reddish-brown and can move between buildings through pipework, especially if there’s easy access to food or water.

Brown-banded cockroach

Brown-banded cockroaches (Supella longipalpa) are more likely to be found in dry areas and higher locations like ceilings or inside electronics. Unlike other species, they’re not tied to moisture, so infestations can start in unexpected places.

Locate cockroach harborage areas

Cockroaches often hide in hard-to-see spots during the day. Common harborage areas include behind appliances, inside cabinets, under sinks, and around leaky pipes. This is where you’re most likely to find signs of a nest, including droppings and egg cases (ootheca). If you're not sure where the roaches are coming from, our pest control technicians can help locate entry points and nesting sites as part of a full inspection.

 

Cockroach removal methods

So, how do you exterminate cockroaches? There isn’t a one-size-fits-all solution, and the right approach often depends on the level of roach infestation, where the activity is happening, and the species involved. Below are a few of the most effective removal methods we may include in a treatment plan.

Cockroach bait

One of the most common cockroach control methods our technicians use is cockroach bait. It’s suitable for indoor locations such as hotels, hospitals, food processing facilities, and kitchens (both commercial and residential). 

Our technicians may use a combination of gel baits and bait stations to increase effectiveness in high-traffic cockroach zones. The bait will be placed in strategic areas around a property where cockroaches are commonly found. When a cockroach consumes the bait, the toxins in the insecticide will not only affect this cockroach, but also will affect other roaches it comes into contact with.

Cockroach fumigation

Fumigation treatment is another option for cockroach control. The fumigation process involves sealing off all or part of a facility where a cockroach infestation is present. A fumigant gas is then introduced into the area to reduce the population. In severe cases, fumigation may be applied in addition to other cockroach control services. Each fumigation technique is tailored to the environment in which it is used.

Cockroach fumigation can be particularly suitable for for businesses in industries such as manufacturing, warehousing, agriculture, food processing, and more.

Heat treatments for cockroaches

Heat treatment is a solution for eliminating cockroaches at any stage of their life cycle. It is both chemical-free and environmentally friendly, providing a solution for homes and businesses such as hotels, schools, hospitals, and restaurants.

Western Exterminator’s heat treatment consists of a mobile system that delivers dry heat between 122°F and 140°F for a monitored period.

How to prevent cockroaches

Cockroaches are hardy insects that can survive in all kinds of conditions and are very resourceful in finding ways into buildings. Here are some practical steps you can take to help keep cockroaches out and prevent an infestation.

  • Eliminate food sources by storing dry foods in tightly sealed containers. Do not leave food sitting out on counters or liquids in sinks or buckets.
  • Clear all food debris and liquid spillage from food prep areas, under sinks, and appliances. Empty your garbage on a daily basis and keep all garbage or compost in sealed bins.
  • Remove pet food as well as water bowls and litter trays before nighttime.
  • Rinse cans, bottles, and plastics before putting them in recycling bins.
  • Declutter by removing old stacks of newspapers and magazines, unused cardboard boxes, and all other forms of clutter from the floor or the bottom of cupboards.
  • Varnish or paint wood shelves to seal them, and wipe them clean regularly.
  • Seal entry points to deny access to cockroaches. Key risk areas are gaps around pipes, drains and common walls with neighboring properties. Even tiny cracks around skirting boards and behind electrical sockets should be plugged to reduce potential hiding areas.

Some people try natural deterrents like essential oils, but these often only repel cockroaches for a short time, if at all. Products like boric acid or diatomaceous earth may help in the short term with the cockroach problem, though results can vary. A professional pest control service can offer longer-term relief by targeting the problem at the source and addressing any potential entry points to keep them away for good.
