How does pest control get rid of Fleas? Since the immature stages of fleas are very cryptic by nature, the first thing the homeowner should do is contact their exterminator for assistance. Most of the time simply using over-the-counter products for controlling fleas will not resolve the root causes of the infestation. A service professional will conduct an inspection and locate areas where the immature stages of the flea population are residing. After completing the inspection, the next step is preparing the flea treatment and management plan. Extermination providers have different methods of providing service. Most national providers offer one-time service or annual plans that include visits every other month and treatment for common household pests, including Fleas. Additional visits are also available in between scheduled visits for any concerns that arise. Overall, recurring service is the most effective way to break the lifecycle of Fleas.
