The answer to 'how to prevent pest control' is to take proactive steps to make your home less attractive to pests. This includes regularly inspecting your home for signs of pests, sealing cracks and crevices, and removing sources of food and water that can attract them.
Start by thoroughly inspecting the interior and exterior of your home, looking for any openings or access points that pests could use to get inside. Seal these with caulk, steel wool, or other appropriate materials. Keep your kitchen and other food storage areas clean and free of crumbs or spills, and store food in airtight containers. Eliminate standing water sources like leaky pipes or clogged gutters. You should also consider using natural pest repellents like peppermint oil or diatomaceous earth in problem areas.
