Types of Insecticide in Flea Collars for Cats
There are two main types of insecticides used in flea collars for cats: solid and liquid types
Solid Insecticide
In its solid state, insecticide and resin are blended together, and the medication is discharged when the collar rubs over the fur of the cat. Depending on what type of insecticide is used, it may either be absorbed by the cat’s skin or be dispersed on top. For the dispersed insecticide, a flea dies on contact. But for the absorption type, the flea has to bite the skin for the insecticide to take effect.
Liquid Insecticide
The liquid type of insecticide is spread as a gas. This type of insecticide is more effective in repelling fleas rather than killing them because the gas will only kill fleas that are near the collar.

What Are The Dangers Of Fleas On Cats
No good pet owner likes to see his or her cat scratching itself to death. However, fleas can cause more than just an annoyance for cats; they can result in serious diseases, like tapeworm infection, anemia, and dermatitis, all of which can infect humans as well. Below are some conditions that fleas can cause.
Tapeworm
What’s so horrific about tapeworm is that they can be transmitted to humans if fleas accidentally get into your food. Tapeworm infection in cats is similar to humans and can result in loss of appetite, stomach ache, diarrhea, nausea, and inexplicable weight loss.
Plague
Fleas can transmit bacteria called Yersinia pestis to your cat. Your cat can get this by ingesting infected rodents or from fleas that previously used rodents as host. Such fleas can bite humans and infect them with the bubonic, septicemic or pneumonic plague.
Murine Typhus
Murine typhus is caused by infected fleas and can be transmitted to humans if they come in contact with the insect’s feces. The symptoms include fever and chills, vomiting, nausea, loss of appetite, cough, and rashes
Anemia
Flea anemia is a serious condition in cats which result in restlessness, weight loss, loss of appetite, dark, sticky stools, rapid, uneven pulse and lethargy in cats. This occurs in cats that are heavily infested with fleas.
How To Check Your Cat For Fleas
We recommend that pet owners check their cats for fleas every few weeks before the infestation takes hold. Cats are able to groom themselves perfectly so it may be difficult for you to know the symptoms.
To check for fleas in your cat’s coat, use a flea comb to brush your pet’s hair, check for drowned fleas in the bath water and keep a close eye on your cat for any signs of excessive scratching and biting.
Adult fleas also leave behind dark spots of digested blood. While brushing your cat’s fur, place a towel beneath it and see if any dark flecks fell off. If you put these flecks in water, they will turn red, indicating a flea infestation.
Once you detect an outbreak, the best thing you can do is to react quickly. Flea collars for cats are a viable option, but you should also support it with other, more effective options like anti-flea shampoos and medicated sprays.
FAQs – Frequently Asked Questions
The Takeaway
Flea collars for cats are a feasible option if you suspect an outbreak. However, the fleas that infest your cat make up only a fraction of the flea population. Only 5% of fleas are adults, 10% are pupae, 35% are larvae, and 50% are eggs. If you want to completely eradicate fleas from your home, make sure you keep your pets, house, and yard clean and groomed at all times.
