How To Control Fleas

As pet owners, we know we might have an occasional flea problem. But if it gets out of control, it can be very stressful, as well as painful and itchy!

In days gone by, fleas were a major concern with the transfer of disease – the bubonic plague or “black death”. Although disease transmission through flea bites in Australia is uncommon, they can transmit tapeworms and murine typhus.

The good news is that there are some clear preventative measures, as well as control products for pets and your home, that allow you to get on top of any flea problem. 

Flea Identification

What do they look like?

  • Flea eggs are white and about 0.5mm in diameter. Although they are laid on the host (cat or dog), they easily fall off, so can be found throughout the house, but particularly concentrated on the areas where the pet rests and sleeps.
  • The larvae are white worm-like creatures with a few hairs. When they hatch they are 1-2 mm long. The larvae go through 4 moults, getting darker and longer. By the time they are ready to pupate, they are up to 5 mm long.
  • Once the larvae is fully developed it spins a pupa. This white oval cocoon is sticky, so picks up dirt making it difficult to see. Under favourable conditions the adult will hatch in 5-14 days.
  • Many people will see a small brown / dark brown spot (1.5 – 3 mm) not sure what it is….. but when it jumps they may suspect a flea. Fleas are insects, so the adults have six legs, although they have no wings. The adults are thin to allow them to move easily through fur / hair on their hosts.

Key Flea Facts

Fleas are only 2-3 mm in size
  • Flea larvae require a warm humid environment to survive. Although they are common in the carpet and pet bedding, they also survive well outside in Summer in damp, sandy soils, in the shade. Any such sites which are visited by the pet (for example under the house or deck) could be a source of infestation. 
  • Flea pupae can remain dormant for many months, waiting for a potential host to walk by before emerging. They detect the vibrations of a passing animal before quickly emerging from the pupa and jumping onto the host.
  • Adult female fleas require a blood meal before laying eggs.
  • Flea pupae are resistant to most consumer insecticides. After a treatment, pupae may continue to hatch for 2-4 weeks after treatment. This can sometimes give the homeowner the impression the treatment has not worked. However, most of these adult fleas will pick up the residual insecticide on the carpet and subsequently die. (However, PestXpert Pro-Fogger is different.).

Signs Of A Flea Infestation

Pets scratching a lot can be a sign of fleas
  • The presence of fleas is often first detected if the cat or dog is continually itching or maybe a member of the household gets bitten. If steps are taken to get control at this stage, you may be able to prevent a major outbreak.
  • Often the major outbreaks occur when families return from holidays. The flea population has got out of control in their absence and there are thousands of adult fleas waiting for a blood meal!

Main Pest Season

Summer is the main pest season for fleas. The larvae are prone to desiccation, so require a warm humid environment to develop. However, in colder climates where heating is used indoors throughout Winter, it is still possible to have a flea outbreak in the colder months.

PestXpert Products For Fleas

To successfully get rid of fleas, you need to carry out a comprehensive flea treatment, which includes a range of actions and requires a number of different products. PestXpert has a range of products to provide excellent flea control.

  • The first step in controlling fleas in the home is to use the Pro-Fogger total release aerosol. Release one aerosol per room to provide complete coverage. The unique formulation uses three actives to penetrate pupae and eggs to maximise control. The stabilising stand ensures the aerosol does not fall over in use. Ensure all safety instructions are read before use. For non-carpeted rooms, instead of a flea bomb you may want to consider a perimeter spray (also spray in any cracks in the floor boards).
  • To hit any dead spots (such as under furniture), use Pro-Spray crawling aerosol or Pro-Spray Indoor and Outdoor to finish the interior treatment.
  • Treat external pest resting areas with Pro Hose-On Tick and Flea or Pro-Spray Outdoor perimeter. Allow to dry before pets can return.

FAQs about Fleas

Adult fleas are a small brown, wingless insect (2-3 mm long). They are thin (vertically) so they can easily move through fur. After a meal blood can be seen in their stomach.

Flea larva are thin translucent worms (with a few bristles) up to 5 mm long.

Flea bites a typically small red, itchy sores. Often they will be around the ankle and lower leg, as this is where the fleas land when they jump up from the ground. The will bleed if scratched and some people will have more of an allergic reaction which can result in hives.

Yes, humans can catch fleas. Most fleas will bite any large animal, so the common cat flea will bite humans and dogs. Although humans get bitten by fleas they tend not to stay on our bodies for very long as we scratch or flick them off as soon as they bite and (for the most part) humans don’t have a lot of hair in which the fleas can hide.

No, flease can’t fly – they are wingless insects. However, they can jump very high – reports suggest up to 60 cm or 200 times their body size! Enough to jump from the ground onto a passing animal.
