Are flea and tick collars dangerous? With flea and tick season ramping up across the country, many pet owners are asking this important question. Some collars contain chemicals that carry warnings like “harmful if swallowed” or “keep out of reach of children,” raising understandable concerns about their safety.
In this article, we’ll answer your top questions about flea and tick collar safety, explain the potential risks to pets and humans, and offer safer alternatives for protecting your pet from parasites.
Are Flea and Tick Collars Dangerous for Pets?
Yes, some flea and tick collars can be dangerous. However, the danger depends mostly on the type of insecticide products used, not on the collars themselves. Some brands use carcinogenic (cancer-causing) chemicals to kill fleas and ticks, but those chemicals can be harmful to humans—especially children—and to pets as well.
Most flea collars work by using a pest control substance that stays on the collar and slowly transfers down onto the pet’s fur. These products either leave a residue or omit a gas that kills the insects on contact. However, a collar that leaves insecticide residue behind can also turn petting and playing with your pet into a dangerous game.
Tetrachlorvinphos, flumethrin, and imidacloprid are some of the insecticides used in common flea and tick collars. If handled inappropriately, absorbed into the skin, or ingested, then they can cause problems in humans and pets. Common symptoms are lethargy, nausea, vomiting, wheezing, rash, or skin lesions.
How to Choose a Safer Flea and Tick Collar
If you think your pet needs a flea and tick collar, talk to your veterinarian. In some states (like our lovely Arizona) flea and tick prevention is not as necessary as it is in others. Unless you do lots of traveling and deep country hiking with your pet, you might not need a flea and tick collar. Either way, your vet can recommend a safe option that does not use harmful insecticides.
Flea and Tick Prevention Tips Without Collars
- Groom your pet often. Regular bathing and brushing can alert you to infestation before it becomes a big problem.
- Wash all pet bedding in hot water once a week.
- If hiking or playing in areas with tall grasses or lots of leaf litter, check your pet for ticks and fleas afterward. Pay close attention to the armpits and folds of the ears.
- If your pet becomes infested with fleas or ticks, be sure to remove them safely. For fleas, this means a bath (dawn dish soap kills fleas quickly), and washing all fabrics the pet comes in contact with in hot, hot water. For ticks, carefully remove the tick with tweezers (trying to keep the head intact) and put it in a container with isopropyl alcohol to kill it.
- Keep pets with fleas or ticks quarantined from other pets.
If you notice an infestation or are worried your pet may have contracted an infection like Lyme disease, contact your veterinarian right away.
