How Good Are Flea Collars?
WouterThere are many different types of flea collars, and not all of them are created equally. The primary ingredient of many collars is imidacloprid or flumethrin, and they are released slowly across your dog’s body. In addition to using a collar, you should also consider topical flea and tick prevention to keep your dog and home free of fleas.
The most effective flea and tick collars are those that contain an insecticide that disorients fleas and kills them on contact. These are generally made of deltamethrin or flumethrin, which is derived from the chrysanthemum flower. However, you should remember that these chemicals can be toxic to humans and other animals.
Flea collars are effective in eliminating the adult fleas on your dog within a few days. However, the timeframe can vary depending on the brand, so you should choose a collar that fits around your pet’s neck. A good flea collar should not have an overpowering smell. It should also have a safety feature that prevents your pet from getting tangled up in the collar.
Aside from being inexpensive, the collar must fit properly to avoid irritation and infection. Many collars are designed to kill only the adult fleas, while others target the larvae, the stage of life in which the flea feeds. The most effective flea collar should also kill the larvae so that the life cycle of the fleas is broken.
