GeneralCharacteristics Adults are 1 to 8mm long and brownish in colour. They have no wings but do have muscular legs for jumping. Metamorphosis is complete, comprising egg, larval, pupil and adult stages.
Pest control Flea control measures will depend on the extent of the infestation. Often it is limited to a single pet. Insecticidal products have been developed to deal with most of these cases and the animal can be treated by strictly following the manufacturer’s instructions.
Efficient regular cleaning will deny the fleas their habitat and any bedding or clothing infected should be thoroughly cleaned or burned. Insecticides can be employed to remove the infestation and prevent re-infestation.
If rats or mice are identified as the culprits, then rodenticides can be used to control them and hence their fleas.

Mole Flea - Hystrichopsylla talpae Adults grow to between 3.5 and 6mm long. Usually located on moles but also found in gardens and outbuildings.
Areas where they are found Adult fleas live exclusively as parasites on warm blooded animals and, although they may prefer specific hosts, they will indiscriminately infect any animal. Cat fleas are responsible for many infestations as their numbers as pets has increased. There is also a general lack of cleaning of their bedding, encouraging proliferation.
Wall to wall carpeting provides an ideal undisturbed environment for flea larvae to develop in the warm temperatures supplied by modern central heating.
Significance as a pest Fleas are capable of transmitting diseases and parasitic worms. The most serious infection they can spread is bubonic plague transmitted to man by rodent fleas. Rodent fleas can also carry murine typhus.
Dog fleas can host tapeworm which, though they usually attack the dog, can also transfer to man.
Flea bites are usually recognised as tiny dark red spots within a reddened area of skin and can be intensely irritating.
