What affects the price

The final bill depends on a few specific things. First, we look at the size of your home and how much ground we need to cover. The type of pest matters too; getting rid of ants is a different process than dealing with a localized rodent issue. We also check the severity of the infestation and how many follow-up visits are needed to keep them away for good. Some homes need a one-time treatment, while others benefit from a recurring maintenance plan. We weigh these factors to build a strategy that works for your specific situation. Exact pricing confirmed free on the call.
