It might not be easy to detect fleas and ticks at home because of their small size and cryptic behaviour. Here are some signs that may indicate a flea or tick infestation. 1. Itching or infected skin: Animals are the primary hosts of fleas and ticks. Your pets might scratch their skin or bite their skin more frequently than usual. 2. Finding them on or around your pets: They can be detected on your pets' body when you comb their hair. Ticks and fleas can also be found around the cage or bedding where the pets rest. 3. Bites: Fleas leave itch bites on humans. The bites are itchier compared to mosquito bites. The reactions that the skin develops from them are usually more severe and include - Rashes - Hives - Blisters
