Pest Control

Pests are living organisms that cause adverse effects in their environment. Pest can be classified as; insects, rodents, microorganisms, animals, and birds.

Pest control refers to methods that are put in place to limit the destruction brought about by different pests.

The three main methods of pest control are;

Physical methods

Chemical methods

Biological methods

Physical methods

It involves exterminating pests through physicals means like setting traps for rodents and traps made of sticky boards for insects. Temperature control can also be used. Hot and cold conditions are used to control small insects by destroying their larvae. It can also involve the physical removal of pests.

It is effective in the small-scale control of pests. One disadvantage of using this method is that it is less effective when the infestation of pests is at a large scale hence less economical.

Chemical method

It involves the use of pesticides to exterminate pests. The chemicals inhibit their development or kill them. They include insecticides for insects, fungicides for fungal, nematicides for nematodes, and rodenticides for rodents

Although a very effective method of pest control, the chemical method has adverse effects on the environment. The chemicals are lodged in the atmosphere, soils, and plant matter affecting the biodiversity in the ecosystem directly or indirectly.

Biological method

It involves controlling pests by the use of other involves the use of parasitoids, pathogens, and competitors to curb pests.

Although friendly to the environment, it can alter the biodiversity when the non-target species are affected. New species are introduced in a new ecosystem altering the balance and hence harming the indigenous organisms.

Pest control is important because most pests are disease vectors that can cause catastrophic epidemics if left unchecked. Some pests cause havoc on farmed fields reducing yields leading to food insecurity.
