“OPEN/CLOSED DOORS” ANALOGY FOR PESTICIDES

Pesticides fit specific receptors in insects. The "open and closed doors" analogy shows how they disrupt vital functions in pests.

Fortunately mammals have receptors that are different than insects.

As an example, the active ingredient in flea dust is safe for the dog.

How the "Open/Closed Doors" Concept Works

In healthy insects, receptors and ion channels open and close to carry signals for movement, heartbeat, and other vital functions.

The pesticide jams the door open or shut, disrupting key pathways and overloading the nervous system.

Different pesticide classes target different "doors" in a pest's body:

·         Neonicotinoids: Keep nicotinic acetylcholine receptors open, causing continuous nerve firing, paralysis, and death.

·         Organophosphates: Block acetylcholinesterase, causing signals to build up and overstimulate the nervous system.

·         Pyrethroids: Keep sodium channels open, causing continuous excitation and the familiar "knockdown" effect.
