To the Editor:

In response to “Tick Time Bomb” (5/10), may I offer three organic suggestions for combating ticks.

Diatomaceous earth, known as DE, which is composed of microscopic marine skeletons, is an inexpensive option. With the consistency of the softest talcum powder, it is death to any insect with an exoskeleton: ants, fleas, ticks, and where I now live, Texas, scorpions and cockroaches. It is completely harmless to people and pets.
