Warmer weather offers the opportunity to spend more time outside with loved ones and pets. But the increase in temperature also leads to more pesky insects like ticks and fleas in your yard. Like many homeowners with furry friends, you may be wondering, “do flea and tick collars work to protect my pets?” Fortunately, a wide range of flea and tick collar varieties are available to keep your pets safe through flea and tick prevention.

There are different versions of flea collars, and each works a little bit differently.

Typically, flea collars are made of plastic and do one of two things: repel fleas or eliminate them outright. Some collars may only provide one function, while others may do both. Either way, the insecticide must be involved for fleas to be repelled or eliminated.

Flea collars that release a strong odor around your pet’s neck repel fleas through the gas coming from the collar. These types of collars tend to be less effective because they only prevent fleas in the area around the pet’s neck, not their entire body.

Other flea collars are designed to release a small dose of active insecticide onto your pet’s fur, slowly spreading across their skin over time and with movement. When fleas and ticks encounter these active ingredients, they are poisoned on contact.

Another type of flea collar releases an insecticide that absorbs into your pet’s fatty skin layer. This causes fleas to die only after your pet is bitten.

Depending on the collar, the active ingredients could include:

There’s much debate on how effective flea and tick collars are. They can be an appropriate preventative measure against fleas and ticks but may not be the best solution for every situation.

Although flea collars are not highly effective when used alone, combining them with other flea control offers better pet protection. For best results using flea collars, experts recommend selecting a brand that contains IGRs (insect growth regulators). IGRs ensure that flea larva doesn’t mature into adult fleas. This keeps flea infestations from reoccurring, as they can do when using a collar that only targets adult fleas and not larvae.

If flea collars work by emitting chemicals, are they safe for your pets and home?

Sometimes it can seem like a double-edged sword to protect pets in a safe manner when eliminating pests. Insecticides are necessary to repel and eliminate fleas and ticks, but large doses for an extended time may cause more harm than good.

For example, flea collars containing organophosphates can cause a toxic reaction in pets and people when exposed to them for a long time.

Additionally, permethrin flea collars, which cost less, can be harmful to cats. Felines tend to be more sensitive to permethrin than other mammals like dogs are. In fact, some cats are so sensitive that they can react to permethrin even after casual contact with a dog that’s been treated with it.

There’s even a risk of permethrin overdose when pet owners place flea collars designed for dogs onto a cat. These products can have up to 45% more permethrin than needed to protect your cat. Signs your cat may be having an adverse reaction to a flea and tick treatment include tremors, seizures, and, in some cases, death.

Most flea collars are recommended for dogs, but do flea collars work on cats too? Yes, there are flea collars that are appropriate for felines, but keep an eye out for any reactions your cat may experience to a new collar. Because they have an increased sensitivity to some flea collar ingredients, cats have a greater risk of skin irritation and other reactions.

Speaking to your veterinarian about choosing the proper flea collar for your pet is highly recommended. Any flea collar can pose some danger to a household with multiple pets, as they may lick or chew each other’s collars, resulting in toxic exposure. But your veterinarian can help you minimize risks and reactions by finding the best collars to meet your household’s needs.

Advantages of flea and tick collars include:

Flea and tick collars are designed to kill most fleas and repel ticks. Depending on the type of collar you have, it may only kill adult fleas and not flea eggs (larva) or young fleas (pupa).

It is also worth noting that some flea collars only emitting an odor around the neck are ineffective at killing or repelling fleas, not in the immediate area around the collar.

If your pet spends a lot of time outdoors, flea and tick collars can be a useful tool to keep them safe. While these collars provide some level of protection for pets, they may also raise concerns when you consider the repellant is in direct contact with your pet and easily accessible to children.
