Physical control refers to mechanical or hand controls where the pest is actually attacked and destroyed. Physical controls are used mostly in weed control. Tillage, fire, removal by hand, grazing and mowing are all used to destroy weeds and prevent reproduction.

Physical pest control does not use harsh chemicals that may harm the environment, home, or business, making it a popular option. Because it does not use toxic chemicals, the pest cannot develop a resistance to it. This factor helps physical pest control deliver effective, long-lasting results.

The most common method of pest control is the use of pesticides—chemicals that either kill pests or inhibit their development. Pesticides are often classified according to the pest they are intended to control.
