Generally, chemical flea collars start to work in the first 24 hours, and the results should be noticeable within 3-4 weeks. As for natural flea collars, they take longer to deliver the results.
Each case can be different depending on various factors, which include: the types of ingredients used, the collar manufacturer, usage, hygiene, the stages of the flea infestation, and your dog’s condition.
The composition of the flea collar affects how long it takes to work.
Chemical flea collar uses active ingredients such as flumethrin, imidacloprid, and tetrachlorvinphos that work faster than natural ingredients. However, exposure to these active ingredients can result in symptoms that vary from a mild to life-threatening.
Natural flea collar uses natural ingredients such as citronella oil, cinnamon oil, polyethylene, Eucalyptus oil, and so on. These ingredients take a bit longer to work and do not kill fleas only repel them, but they are safer for your dogs.
Best dog flea collar brands usually offer faster and better results than the cheap ones.
For maximum result, it is important to read the manufacturer’s instruction manual first before using the collar. For example, you might not know the flea collar that you buy is not waterproof. Accidentally exposing the collar to water can make the collar less effective.
To make the collar work faster, you need to keep your dog, and her environment clean too. Some steps that you can take:
- Clean your dog with flea soap or shampoo.
- Replace your dog’s bedding to prevent re-infection.
- And vacuum your floors regularly.
