Exterminators are pest control professionals who specialize in determining how pests got into your home, killing them off using the most humane methods possible, and ensuring that they do not return to your home. When it comes to mice, exterminators use a variety of methods to determine whether you need professional mice control services, including inspecting for access points. Once they have identified the entry points, exterminators seal them up with sheet metal, wire mesh, or hardware cloth to prevent the entry or exit of mice. If exclusion isn’t possible, professionals place snap traps around areas with droppings, or they use bait stations to kill large mice colonies over time. For severe infestations, fumigation may be the only solution. Exterminators also use repellents that they apply along the perimeter of your home to keep mice away. Some of the chemicals that exterminators use for mice pest control include phosphine and formaldehyde. After extermination, it is essential to sanitize your home properly to ensure that it is free of dangerous bacteria and viruses that mice can carry.
