Some science behind the scenes

Coleoptophile

A substance able to kill or inhibit the activity of beetles. 

Beetles are a group of insects that form the order Coleoptera . The word "coleoptera" is from the Greek κολεός, koleos, meaning "sheath"; and πτερόν, pteron, meaning "wing", thus "sheathed wing", because most beetles have two pairs of wings, the front pair, the "elytra", being hardened and thickened into a shell-like protection for the rear pair and the beetle's abdomen.
