  • Insecticides have been around for many years. One of the more popular insecticides belongs to a group known as pyrethrins. These medications are placed on the animal's skin to kill fleas and ticks.
  • Pyrethrins were originally developed from the Chrysanthemum plant and work by affecting the nervous system of the insect, resulting in death.
  • As science progressed, synthetic forms of pyrethrins were developed, including permethrin. This product has more stability and potency than the natural pyrethrins.
