Boric Acid as an Insecticide

Overview

• Boric acid is a weak, monobasic Lewis acid of boron.
• It is widely recognized in alternative health and pest control circles as a low-toxicity mineral compound effective against crawling insects.

Primary Borate Compounds

• Orthoboric acid (commonly known simply as boric acid or boracic acid) is the specific chemical compound utilized for insecticide powders.
• Related borate compounds often used similarly include disodium octaborate tetrahydrate (DOT) and sodium borate (borax).

Mechanism of Action

• Abrasive Exoskeleton Damage: The powder particles scratch the protective waxy outer layer of insects, leading to dehydration.
• Gastrointestinal Toxicity: When insects groom themselves and ingest the powder, it acts as a metabolic poison, disrupting their cellular processes and digestive system.

Nutritional and Mineral Context

• From a biochemical perspective, boron is a trace element involved in various physiological functions.
• However, in the context of pest control, concentrated borate powders are strictly used for topical and environmental application rather than internal consumption, due to potential toxicity at high doses.
