How does a Barss flea collar work? - briefly
The collar contains a controlled-release formulation of insecticidal agents that disperse onto the animal’s skin and coat, killing fleas on contact and inhibiting their development. Continuous diffusion maintains a lethal concentration for the product’s advertised period, providing ongoing protection.
How does a Barss flea collar work? - in detail
The Barss flea collar delivers insecticidal agents through a controlled-release matrix embedded in the fabric. Active compounds, typically a combination of imidacloprid and pyriproxyfen, are dispersed uniformly within a polymer resin. Body heat and natural movement of the animal cause the resin to soften slightly, allowing a steady diffusion of the chemicals onto the skin surface.
Once on the skin, the agents spread via the animal’s natural oil secretions. Imidacloprid acts on the nervous system of adult fleas, binding to nicotinic acetylcholine receptors and causing paralysis within minutes. Pyriproxyfen interferes with the development of flea eggs and larvae, preventing the next generation from maturing.
The collar’s design ensures a constant low‑level exposure:
- Polymer matrix releases a measured dose each hour.
- Heat‑activated diffusion maintains concentration despite changes in ambient temperature.
- The collar’s adjustable fit keeps the material in close contact with the neck, the region where fleas commonly congregate.
Efficacy lasts up to six months, after which the resin’s active content diminishes below therapeutic levels. Proper use requires:
- Selecting the correct size for the pet’s neck circumference.
- Securing the collar snugly, allowing two fingers to slide underneath.
- Avoiding removal for bathing or grooming unless the manufacturer specifies a water‑resistant version.
Safety considerations include keeping the collar away from the eyes and mouth, and monitoring for signs of irritation. The product is unsuitable for cats, as the active ingredients can be toxic to felines. In environments with heavy flea infestations, supplemental topical or oral treatments may be recommended to achieve rapid control.
