The answer to 'how often for cockroach control' is that regular, ongoing treatment is typically recommended for effective cockroach control in homes. Most pest control experts advise homeowners to schedule professional cockroach treatments every 3-6 months to maintain control and prevent reinfestation.
Cockroaches are resilient pests that can quickly reproduce and spread throughout a home. Quarterly or semi-annual treatments help eliminate existing cockroach populations and prevent new infestations from taking hold. The frequency may need to be increased if a severe cockroach problem is present, or decreased over time as the infestation is brought under control.
