Lime for Fleas & Ticks: Myth from Bygone Era

Heard lime kills fleas/ticks. True?

Historical Context

Decades ago, benzene hexachloride (BHC) insecticide was mixed with limestone. Lime was just the carrier. BHC is banned.

Calcium carbonate does not kill or repel fleas, ticks, or any pest.

Use labeled pet/yard treatments (fipronil, permethrin, etc.) and vet-recommended pet preventatives.
