The cost of professional cockroach extermination can vary widely depending upon your geographical location, the size of the residence that needs to be treated, and the specific extermination company you’re getting a price quote from.
Luckily, most people find that they can handle cockroach extermination themselves and be quite successful at it, with only the largest infestations requiring a professional cockroach extermination company.
If done yourself, cockroach extermination can cost as little as a dollar or two per month, as most cockroach control products are fairly inexpensive and can be used for many months of protection.
I would recommend that you first try do-it-yourself approach to cockroach extermination because of the high likelihood that you will be successful, and also to save yourself some money.
In the unlikely event that this fails, I would recommend that you at that point moved to getting price quotes from a professional exterminator.
