CLEAR FLEA COLLAR is an insecticide-impregnated collar for dogs and cats from BOB MARTIN with generic dimpylate.
Diazinon (also called dimpylate) is a veteran organophosphate introduced in the 1950s by GEIGY (later CIBA-GEIGY → NOVARTIS). It is a broad-spectrum insecticide and acaricide effective against fleas and ticks. It was abundantly used until the 1990s in livestock and pets, in agriculture and against household pests. Nowadays it has been vastly replaced by modern, less toxic compounds.
- Most topical products kill or sterilize the parasites before they bite and suck blood on the pet, whereas systemic products kill or sterilize the parasites only after their blood meal.
- Topical products cannot be vomited.
- Spot-ons and collars are very convenient to administer.
- There is a larger choice of topical products.
But topical products have also some disadvantages:
- Topical products contaminate the pet's hair coat and it is advisable for children and also adults to avoid contact with the pet for several days after treatment.
- Topical products may not control parasites in some parts of the pet's body (e.g. the ears, below the tail, between the legs, etc.), whereas systemic products reach the blood-sucking parasites through the blood wherever they are.
- Efficacy of topical products may be reduced or shortened through exposure to dirt, sun, shampooing, washing, rain, baths, etc., whereas efficacy of systemic products is independent from these factors.
