The answer to 'DIY quarterly service control' is that with proper precautions, you can perform quarterly pest control services yourself to maintain a pest-free home. This involves applying targeted treatments to common entry points and high-risk areas around the exterior of your home on a quarterly basis.
To do this safely and effectively, start by thoroughly inspecting your home's exterior for any cracks, crevices, or other potential entry points that pests could use. Seal these up with caulk or other sealant. Then, apply a residual insecticide treatment around the perimeter of your home, paying close attention to areas like the foundation, windows, doors, and utility entry points. Be sure to follow all product instructions and safety guidelines carefully.
