The Entomologist’s Diary – Episode 51: Insect Chemical Warfare – Toxins, Sprays and Defensive Chemistry 💣🪳🧪

Today, I explored how insects use chemistry as a weapon. Bombardier beetles, for instance, eject a boiling chemical spray when threatened — a perfect mix of hydroquinone and hydrogen peroxide that explodes on contact. Ants use formic acid, while some caterpillars release foul-smelling compounds to deter predators. Insects don’t just…


Today, I explored how insects use chemistry as a weapon. Bombardier beetles, for instance, eject a boiling chemical spray when threatened — a perfect mix of hydroquinone and hydrogen peroxide that explodes on contact.

Ants use formic acid, while some caterpillars release foul-smelling compounds to deter predators. Insects don’t just fight — they formulate.

In my journal:
“Insect battles aren’t fought with claws, but with chemistry.”

Next episode: symbiotic microbes and the chemicals they produce for their insect hosts.
