The answer to 'how often for pest prevention control' is that most experts recommend scheduling professional pest control treatments every 3-4 months for effective prevention. Pests like ants, cockroaches, and rodents can breed rapidly, so regular maintenance is key to keeping them under control.
Quarterly pest control visits allow the technician to inspect for any new infestations, treat problem areas, and apply preventative measures to deter future pests. This frequency is generally considered the optimal balance between cost, convenience, and comprehensive protection for most homes.
