Fleas do more than just irritating the skin of your pets. They are actually able to jump from your pets onto your body and cause massive irritation to the skin. Fleas are also responsible for the spreading of viruses.
There are many species of fleas present but they share many common characteristics. Most fleas are around 3mm long and are usually red or brown in colour. Adult fleas feed on the blood of their host, while larvae feed on dander, adult faeces and partially digested blood expelled by adult faecal. Most adult flea mate and lay their eggs on their host. Mating occurs right after their first meal of blood. Fleas are also attracted to heat, and carbon dioxide released from their host.
