How do Flea Collars Work?

Fleas are uncomfortable and potentially harmful bugs that latch on to your dog’s skin and feed on her blood. A flea infestation will be miserable for your dog, and excessive scratching and licking can cause skin infections. Flea collars are a preventative measure that can protect your pup from both fleas and ticks.

There are two different types of flea collars available. One variety emits a gas that is toxic to fleas, but this type of collar usually only kills fleas in the nearby vicinity. Fleas around the base of the tail can often survive. This type of collar is best used inside of a vacuum bag instead to kill any fleas that you suck up while cleaning.

The other type of collar has a medication that is absorbed into the fat layer under a dog’s skin. When a flea bites, it is poisoned. This type of collar is much more effective at preventing a flea infestation.

Flea collars don’t necessarily need to be worn at all times. If you’re planning to take your dog out to a thicket where there might be fleas or ticks, you can have her wear a flea collar for just that day. Make sure to remove it when your pup no longer needs to wear it.

Don’t put a flea collar on your dog if she’s already getting another form of treatment such as an oral medication or a topical ointment. Overmedicating your pup could result in an expensive trip to the vet. The neurotoxins used in flea treatments can build up in your pooch’s body and create health problems.

Flea collars are designed just for pets, so be careful when handling them. Human skin is sensitive and not protected by a layer of fur, so the toxins can easily get on your hands. This could be harmful if you accidentally touch your eyes or pick something up to eat. Always wash your hands after touching your pup’s flea collar.

Other pets such as cats can also be harmed by a flea collar designed for dogs. If you have any other pets that need a flea treatment, get them medication that is specifically geared towards their species.

What to Look for in a Flea Collar

One of the most important things to consider when looking at flea collars is your dog’s size. Your pup should not be able to reach down and gnaw on her flea collar since ingesting the toxins inside can be dangerous for her health.

Flea collars are designed to be safe for a dog’s skin, but not necessarily her digestive system. Try to find a flea collar that is not big enough for your dog to reach, but not so small that it irritates the skin around her neck.

One of the best things about flea collars is that they can last for months, unlike most topical medications. Using a flea collar may be more convenient to some people that remembering to apply an ointment every thirty days. Make sure that you don’t use the collar longer than advised by the manufacturer or it could lose its effectiveness.

Safety Precautions

All flea collars use toxic chemicals, or insecticides, to get rid of fleas. In small enough doses, these insecticides are safe for your pooch but deadly to those pesky fleas. Always check the active ingredients in your dog’s flea collar since some of these chemicals are safer or more effective than others.

Deltamethrin, a synthetic pyrethroid, is one of the safest insecticides out there. It has minimal effects on both humans and our furry friends, but it’s not the only acceptable choice.

Pyriproxifen is another safe insecticide that targets eggs and larvae instead of adult fleas. It makes them unable to reproduce, so they die within a generation. Propoxur destroys the nervous system of fleas to kill them, but is dangerous for humans. A collar containing propoxur should be handled with care.

Tetrachlorvinphos (TCVP) should be avoided whenever possible. Although it does kill fleas, it is harmful to both you and your pets. TCVP is also a human carcinogen. Children are especially vulnerable to the effects of TCVP. Some collars still use this insecticide, but there are plenty on the market that use safer chemicals.

A high quality, comfortable flea collar can be a lifesaver for both you and you dog. Your pup won’t be in pain, and you won’t have to worry about fleas getting tracked into your house. Flea collars are a safe, effective preventative measure in both the long and short term.
