You've probably heard the phrase, "You get what you pay for." When you hire an exterminator with a poor reputation, you will receive poor service in return. There could be a number of reasons why the service fails.
Failure to eliminate a German roach infestation generally stems from one of two reasons. The first reason is lack of training. Treating for German roaches is complex and requires extensive field training. The second reason is lazy technicians that are in and out as quickly as possible so that they can move on to their next property. When technicians rush through a service, they leave many surfaces untreated.
For a palmetto roach treatment, we act as a detective more than anything else. If the technician didn't apply the right products in the voids where these roaches are breeding, they will not die. Sometimes there is a moisture problem, such as a leaky pipe or a roof leak, that creates the conducive conditions for American roaches to breed. Inspecting and treating the attic is the key to eliminating an active infestation and to preventing future problems. Hire a pest control company that is willing to do this and has the knowledge to identify potential moisture problems. In very rare situations, American roaches can gain access to the home when there is a breach in the plumbing system.
The real truth is that when you hire a pest control company, you are actually paying for knowledge. We all have access to the same products and the same tools, but a licensed pest management professional will know how to apply them as effectively as possible.
