How does bifenthrin compare to malathion?

Bifenthrin and malathion are both pesticides, but they belong to different chemical classes and have distinct modes of action. Bifenthrin is a synthetic pyrethroid that primarily targets the nervous system of insects, providing effective control over a wide range of pests with low toxicity to mammals. In contrast, malathion is an organophosphate that inhibits cholinesterase, affecting insect nerve function but posing a higher risk of toxicity to non-target organisms, including humans, at certain exposure levels. Overall, bifenthrin is often preferred for residential use due to its lower toxicity profile.
