How Much Does a Roach Extermination Cost?

Nobody likes finding a family of roaches scuttling around their kitchen in the late hours of the night. Roaches are not merely nasty to look at. When they come into your home, roaches carry bacteria such as salmonella and E. Coli on their backs, making their presence not simply an annoyance, but a genuine threat to your family’s health. While there are plenty of over the counter sprays and repellents you can purchase to kick the roaches out, these solutions are sadly short-lived and do not solve the problem in the long term. The best approach is to hire an exterminator.

A professional exterminator will achieve more than simply eliminate the roaches. They will use their expertise and knowledge to investigate why roaches arrived at your home, to begin with. They will work alongside you to ensure your home becomes a roach free home, no matter how many visits this requires. The extermination process is normally comprised of a preliminary assessment, treatment and follow up meetings. Ensure your exterminator is insured and licensed before hiring them!

So how much does an exterminator cost for roaches? The roach exterminator cost varies between $100 and $400 for a standard treatment. You may also have to factor in follow up checks to ensure the job was successful. While the cost of extermination may seem high upfront, it pays to live in comfort and health. The cost is well worth it. Factors such as the type of cockroach, location of the infestation, the extent of damage and what tools are used, and whether follow-up visits are necessary to influence the price of extermination.

Type of Roach

An exterminator will approach his or her job differently depending on what kind of roach has chosen to infest your home. The most common roaches are German and American roaches. Smaller roaches are generally more difficult to exterminate than larger roaches.

Smaller roaches, such as the German or Brown-Banded roach will live and breed indoors, dwelling especially in areas of moisture such as kitchens or bathrooms. These roaches can carry bacteria that lead to food poisoning and dysentery in humans. Children are especially at risk of developing an illness or having an asthmatic reaction to roach feces, body parts, and saliva.

Larger roaches live and breed outside, and travel indoors during colder months in search of heat, food, and moisture. The most common large roach is the American roach, and while they are slightly less likely to carry disease compared to the German roach, they can still promote an environment of illness in your home.


Because roaches breed quickly, their location has a direct impact on how difficult it will be to exterminate them. As nocturnal creatures, roaches are usually drawn to warm, dark spaces, burrowing under stoves, sinks, and refrigerators. Smaller roaches live and breed indoors and enter homes via boxes, luggage, purses, and furniture and can also travel through plumbing systems. They congregate in areas of moisture and food such as bathrooms and kitchens. Larger roaches live and breed outdoors, but typically travel into your home and live off organic materials in woodpiles, basements, attics and under roof shingles. Larger roaches can be exterminated by spraying insecticide around entry points to your house, at the discretion of your exterminator.

Your geographic location may also determine the size and scale of your infestation problem. Roaches are more common in the summer months, an in areas of high heat and humidity. Keeping a dry and well-ventilated home will do a world of good for preventing the worst of infestations.

Size of Home

Generally, it follows that the larger the home, the larger the infestation can potentially be. Roaches breed extremely quickly. Female roaches do not even need male roaches to mate, and they lay thousands of eggs a year. The larger your home, the more opportunities for roaches to breed and burrow into the nooks and crannies of your home. During the initial assessment, your exterminators will consider the size of your home, and whether this will make his or her job more challenging.

Level of Damage

Of course, the more damage your exterminator observes, the higher the cost will likely be. Cockroaches don’t only feed off your food; they also chew away at books, clothing, and furniture in your home. More damage is indicative of a greater infestation problem, and thus, a higher cost. A bigger infestation problem will also warrant more follow-up appointments after the first round of treatment.

Tools Used

Larger roaches are exterminated with insecticides and granular baits. They are generally easier to exterminate than smaller roaches. Smaller roaches are usually treated with roach bait and insect growth regulators. Other common approaches include using glue traps, gel bait, bait stations (also known as “roach hotels”), boric acid, desiccants, fumigation, “foggers” and mist-based extermination tools. Your exterminator will have their own preferred method, and insecticide and roach fumigation cost will be largely dependent on whatever tools they employ to ensure roaches do not return to your home.

Follow Up Appointments

Most roach infestations require several rounds of treatments and checks to ensure the root problem is eliminated entirely. These follow up visits will certainly add to the expense, but it is always better to be safe than sorry. A particularly difficult infestation may require up to four to six months of treatment and follow-up visits.

Preventing Infestations

In the meantime, there are many measures you can take to prevent roaches from coming into your home in the first place. Simply maintaining good hygiene in your home; washing your dishes and keeping a tidy kitchen, regularly vacuuming your floor and removing excess moisture from your bathroom and kitchen are all ways you can reduce the risk of infestation. If you can identify entry points to your houses such as holes or cracks along your door or wall, be sure to seal them up. Preventing an infestation in the first place will help keep the cost of extermination down if or when an exterminator does knock on your door.
