Here's why:
* Low Concentration: Flea collars are designed to release a small amount of insecticide over time, and the concentration of the active ingredient in the air you breathe is very low.
* Skin Contact: The primary method of exposure to the insecticide is through skin contact, not inhalation.
* Safety Regulations: Flea collars are regulated by agencies like the EPA in the US, and they must meet certain safety standards to be sold.
However, it's important to remember:
* Individual Sensitivity: Some people may be more sensitive to certain chemicals than others, and may experience mild reactions like headaches or nausea from exposure.
* Children and Pets: Young children and pets should be kept away from flea collars, as they are more susceptible to the effects of insecticides.
* Proper Use: Always follow the instructions on the product label carefully.
If you are concerned about the safety of a flea collar, it's best to consult with your veterinarian or a medical professional. They can provide you with the most accurate and up-to-date information.
