Some people cite the dangers of using pesticides, but not acting can come with its own set of dangers, sometimes even lethal ones. Mosquitoes for instance can transmit diseases to their hosts which can include malaria, yellow fever, and West Nile virus to name a few. Ticks can cause Lyme disease, Tularemia, and Rocky Mountain spotted fever. Preventive measures such as the use of pesticides can help thwart these threats. Pesticides and other forms of pest control can pose health risks, but mostly to those that do not heed warnings and familiarize themselves with product labels.
The mildest side effect from home-appropriate pesticides is irritation to the body. This can be skin irritation, eye irritation or irritation on any area that has come into contact with the pesticides. This often happens when people do not heed the warnings of wearing masks, washing hands, and other precautions, or do not give it enough time between using the products and coming into contact with the same surfaces.
More severe consequences can include pain in the abdominal area, vomiting, dizziness, headaches, dermatitis, neurological damage, poisoning, and impaired fertility—and these are very likely effects of not protecting yourself from fumigation-level poisons. Now you see the need for caution! Pesticides and poisons are necessary, and when handled correctly pose little threat.
