A general pest control plan costs from $400 to $950 per year or from $30 to $50 per month, on average. Sometimes, hiring a professional pest control service is necessary to get rid of a severe pest infestation.

Cost. Up front, the cost of a professional insecticide is higher than that of a DIY hack, with most one-time pest control services costing between $250 and $550 and many DIY methods coming in somewhere between $20 and $50.

Most store-bought pest solutions like insect repellant or rodent traps are reasonably priced; you're unlikely to spend more than $100 for a single DIY pest project. But professional pest control businesses are perfect for tackling large, stressful, confusing or bothersome pest infestations.
