Does WD40 Kill Wasps? Why?

So does WD40 kill wasps? How come WD40 can kill wasps? Spiracles are tiny apertures on the body of all insects, including wasps. These apertures allow the insects to breathe by taking oxygen and exchanging it for CO2.

WD40 comes in handy here. As it penetrates and plugs the spiracles, this liquid kills wasps. As a result, no air flows through. WD40 has been designed to target tiny holes especially.

When WD40 comes into contact with the heated temperature of the wasp, it will also froth. This suffocates the wasps’ lungs and causes them to die.

The wasp will die of poison even if it does not choke. Once inside the body, WD40 is harmful. In rare situations, the poison might be more lethal to wasps than asphyxia.
