Permethrin is an “active” ingredient used in conventional pesticides and insecticides to kill insects by making their nervous system hypersensitive to stimuli, killing them with a train of impulses after exposure. Many insects are actually building up a resistance to permethrin, and require a stronger or more frequent dose to kill them. Examples of these pests include cockroaches, flies, fleas, bed bugs, and ticks. This means stronger conventional pesticide formulations and repeat exposure in homes, lawns, parks, and schools. There is current research around the theory that insects have evolved and can metabolize the conventional pesticides as a food source. This makes them conventionalpesticide resistant and increasingly harder to kill with chemical based conventional pesticides. Because permethrin is commonly used in food production, home pest control, and pet care products, the impact is even more dangerous for our pets and families.
Stronger conventional pesticides and increased exposure to the pests also means an increased exposure and probability of harmful side effects to humans and animals.
Permethrin attacks people and animals in the same way that it kills pests. When exposed to permethrin, people and animals experience repetitive nerve impulses, inhabiting the enzymes. This creates a strong effect on the nervous system, which releases increased and decreased levels of neurotransmitters, causing short term and long term effects. Permethrin inhibits the nervous system, immune system and reproductive system insects, humans, and animals. Women and children are at the highest risk for illness and neurological problems related to pesticide exposure. As mentioned in the first installment of Permethrin Exposed, permethrin has been deemed a possible carcinogen, which translates into it having “cancer-causing” effects on humans and animals. Pesticides are also thought to contribute to neurological conditions and disorders.
