Molecular Structure:

In 2005, the EPA required Hartz Mountain Industries to give off uses of several flea and tick products containing phenothrin which were related to a series of adverse reactions, such as salivation, hair loss, tremors, and numerous deaths in cats. In the short term,  new warning labels on the products wrer called for by the agreement.
Until March 31, 2006, the sale and distribution of Hartz's phenothrin-containing flea and tick products for cats has been stopped. But Hartz flea and tick products for dogs were not influnced by EPA's product cancellation order, and Hartz continues to use phenothrin  in many of its flea and tick products for dogs in a concentration of 85.7%.

Phenothrinis a synthetic pyrethroid which can kill adult fleas and ticks as well as head lice in humans. d-phenothrin is used as a component of aerosol insecticides for domestic use
