Fleas are small brown or almost black insects and wingless. They usually measure less than 5 mm long (2 to 3 mm for most species, exceptional cases 9 mm).

Adult fleas are bloodsuckers, that is to say they feed on blood to survive. However they may survive several weeks without blood meal. Several species can suck the blood of various animals.

The cat flea and dog flea can be passed on to dogs and sometimes cat, the nematode parasite commonly called
“heart worm”.

They’re more common and more severe in late summer and early fall. It is therefore recommended to regularly examine your pets during this period.
