Are Flea Collars Safe For Humans?

Fleas are a great risk to pets. The easiest treatment people think of just after hearing fleas are flea collars. However, flea collars effectively prevent fleas from the pet, but they aren't beneficial if your pet is already suffering from flea infestation. The question that arises is that are flea collars safe for both humans and pets?

Flea collars can be dangerous for your dogs as well as for your family. And at the end of the day, the flea collars can have many side effects than benefits. The flea collars include ingredients that are harmful to the health of pet owners also. The toxins used in the flea collars can easily flow to the surrounding when your pet sits on your sofa or rubs its neck with you.

Ingredients Used in Chemical Flea Collars

The chemicals used in the flea collars are from the group called organophosphates. These compounds are a combination of alcohol and phosphoric acid. Organophosphate is the base unit of many pesticides and a building block of many biological weapons, including nerve gas. Since the flea collars are made up of the organophosphate that works to attack the fleas’ nervous system directly, studies have shown that if the pet or pet owner is exposed to such chemicals for a long, it can affect the nervous system of them also. Hence because of such side effects, flea collars have been banned by many countries.

1. Tetrachlorvinphos Risks

Tetrachlorvinphos is the most used ingredient in the flea collar. The pesticide directly targets the central nervous system in humans and pets also. The kids around the pet are more at risk as they have a weaker immune system than adults. The tetrachlorvinphos is listed as a highly potential; carcinogen by the environmentalist.

2. Propoxur Risks

The second most commonly used ingredient in the flea collar is propoxur. It causes many neurological problems in pets as well as humans. In addition to this, propoxur is the top listed carcinogen. According to EPA., not only this but the natural resources defence council researched the risks of the propoxur and signed a petition to the EPA in 2011 asking for the council to cancel the use of propoxur in pet collars.

3. Exposure Risks

It is essential to follow the warnings labelled by the manufacturers on the product to avoid exposure and to wash your hands after using the flea collar on the pet. But the research has shown that after every three days, the residue from the collar increases the acceptable exposure level for kids. Even after two weeks, the pets have more than 75 percent of unsafe toxin levels. The harmful ingredients contaminating the air quality thus increase health risks for the pet owner and the family members who never have been in touch with the pet or the pet collar.

A Tip To Remember

Look For Safe Alternatives

As a pet owner, you must look for a safer alternative for both you and your pet’s health. It might be possible that the prescribed strength treatment can be more expensive but very effective than the other treatments. The prescribed medicines are suggested according to your pet’s size and the pet’s reaction to the medicine. Along with this, there are many topical and oral medications available that eliminate fleas without causing any harm to your pet and you.


Flea collars are not safe for humans, especially for kids and pregnant women. The risk is far beyond the normal. The most common causes of flea collars are behavioural issues, hyperactivity, skin sensitivity, motor development, and learning disabilities. After doing much research, the National Resources Defense Council has declared a flea collars ban in many countries to minimize health issues. Lastly, please read the information and treat the flea infestation accordingly to the safest method suggested by the vet.

Best of luck!
