Releases diazinon progressively to kill fleas within hours and prevent tick infestations.
PREVENDER collar treats external parasitosis in dogs caused by fleas (Ctenocephalides canis and Ctenocephalides felis) and prevents infestations from ticks (Rhipicephalus sanguineus, Dermacentor variabilis, and Otobius megnini).
The active ingredient, diazinon, is an organophosphate insecticide that inhibits cholinesterase, leading to irreversible poisoning of the parasite. Due to its lipophilic nature, it diffuses rapidly through the animal's fat skin layer and is released progressively over time, acting against fleas within hours of placement.
Each collar provides continuous activity for 200 days. For large dogs, the collar contains 6.30 g of diazinon (42 g total collar weight).
