The answer to the difference between preventive treatment and reactive treatment is that preventive treatment is proactive, aiming to stop pest problems before they start, while reactive treatment is a response to an existing pest infestation.
Preventive treatment involves regular, scheduled applications of pesticides or other control methods to create a barrier and make the environment less attractive to pests. This is often done on a seasonal or annual basis. Reactive treatment, on the other hand, is implemented when pests are already present and causing damage. It typically involves more intensive and targeted pest control measures to eliminate the current infestation.
