Biological control is the use of living organisms to suppress pest populations, making them less damaging than they would otherwise be. Natural enemies of insects play an important role in limiting the densities of potential pests. These natural enemies include predators, parasitoids, and pathogens. Pest control devices use mechanical or physical methods to trap, destroy, repel, or mitigate a pest as glue boards, noisemakers, shiny foils that frighten birds, and bug zappers are pest control devices. Insect species typically respond to warmer temperatures with faster developmental rates and greater reproductive potential, which can increase both the number of generations within a season and the rate of population growth. There are several non-chemical methods available to eradicate or reduce the amounts of pathogens in the soil. The use of solar, dry or steam heat is the most effective non-chemical means to disinfect soil. The time to treat soil is before seeding or transplanting. Use disease-free and weed-free seed to prevent diseases and weeds from being introduced. Control alternate host plants of insects and diseases. Minimize moisture conditions optimum for disease development by carefully managing irrigation water applications. Sweep up individual bugs and nests and cut off their air supply by placing them in sealed vacuum bags. Use mousetraps, jar traps, pheromone traps, and other nontoxic bait. Dust cracks and crevices with boric acid powder, which will slowly poison crawling insects but is less toxic to humans than pesticides are.Natural pest control refers to pest control methods that rely on natural (chemical-free) remedies. From essential oils to fly traps to food grade Diatomaceous Earth, several natural elements can help control the pest population. The use of biological control suppresses the pest populations, making them less damaging than they would be. They play an important role in limiting the densities of potential pest and include natural enemies such as predators, parasitoids, and pathogens.
