Adults, 1.5 - 4mm long, dark brown or black in colour and have highly developed jumping legs.
Flea eggs, 0.5 mm long, oval shaped and pearly white in colour.
Larvae, up to 5mm long, and semi-transparent white.
Up to 20 eggs are laid after each blood meal and a single female may produce 800 – 1000 eggs during her lifetime, which may be as long as two years. The eggs hatch in about one week to give white, threadlike, legless larvae 1.5 mm long. Depending on temperature, these eggs will usually hatch within 2-16 days. The emerging larvae are active, hiding from light and feeding on dust and flea droppings. It takes between 7-10 days for each larvae to fully develop through 2-3 moults. A cocoon is spun by the larvae where they will pupate into an adult Flea Fleas will remain dormant in their pupa in unoccupied premises and will be stimulated to emerge by the vibrations set up by a passing host. This explains the occasional mass attacks which take place in deserted premises. The development cycle from egg to adult is normally completed in 4 weeks but at low temperatures will take much longer.
Pre-treatment: Flea infestations must be attacked simultaneously from a number of angles. Firstly, the adult fleas should be controlled either while transiently on the host or in its resting places around bedding, pets' baskets, carpets, sofas and chairs. The use of a vacuum cleaner may assist treatments by physically removing all stages from floors and furnishings but the bag contents should be quickly disposed of in an outside bin. Any cats and dogs should be treated for fleas with a veterinary product recommended for this purpose. Pet bedding should be destroyed or washed in hot soapy water to eliminate fleas. All articles such as clothing, toys, boxes etc., should be removed from the floor to enable the entire surface to be treated. All tiles and concrete floors should be swept and washed or vacuumed.
Treatment: All floor areas should be treated with a residual insecticide from skirting board to skirting board; a heavier treatment may be needed on thick pile carpets and uncovered floorboards. Remove pets and cover aquariums. Advise householder that pets should not be allowed back into the house until the treatment has completely dried. Advise not to vacuum for at least 14 days after the treatment to give the insecticide time to eradicate all stages of the flea infestation. Advise that due to new hatching, fleas may be seen for a few days after treatment. Ask them to wait at least 10 days before calling back.
