Certain pests – cockroaches, flies, and rodents – can spread harmful bacteria, including salmonella or E. coli. The saliva, feces and shedding body parts of cockroaches can trigger both asthma and allergies, especially in children. This makes preventing and eliminating pests critical to good health.

The pros of being a pest control technician include job security, working with little to no supervision, and decent pay, while the cons are susceptibility to the elements, working in small cramped spaces, and dealing with job hazards such as snakes, spiders, wild animals, and dangerous chemicals.

Physical pest control can be a safe and non-toxic option. Still, it may be labor-intensive and less effective against specific pests or infestations. Pros: safe and non-toxic; suitable for small-scale infestations. Cons: labor-intensive; less effective against certain pests or large infestations.

Many of the buzzing, flying and crawling critters have a very important job to do for the environment. Some examples: bees and butterflies pollinate and are food makers, dung beetles compost, ants and termites recycle, silk moths make silk and worms filter and amend the soil.
