How do Flea & Tick Collars work?

Flea and Tick collars

Most flea and tick collars are an option for dogs and cats suffering from pre-existing pests.

That is, they may be effective in preventing infection, but not curable.

Few recent developments in tick collar designs have introduced long-lasting 8-month collars that can treat infections.

There are two basic functions of flea and tick collars.

Flea and Tick collars
  • Repellent: Releases a type of repellent gas.
  • Treatment: Other types include medications that penetrate the fat layer on the dog’s skin or into the active skin oils of the dog using natural skin oils. When the first type is used, the dog must be bitten for a pesticide to kill them. The second type of treatment collars release active substances that kill flies and ticks before they bite on contact.
