Flea, Tick and Worm Advice

What to Do When you Spot Fleas

If you see fleas on your untreated pet, chances are that there are many, many more lurking close by. The adult fleas on an untreated pet will not only take a blood meal courtesy of your pet, but will also be laying eggs — up to 50 a day, in fact. These tiny eggs are like grains of sand that slide off your pet and into your home. In as little as one day (or as long as 12 days), the egg hatches and out wriggles a flea larvae. About half a centimeter long, the larvae is very hard to see. These hide in dark places such as within carpets, under furniture or in the cracks and crevices of floorboards. After a couple of weeks, the larvae become cocooned. The cocoon is sticky and not always easily dislodged even by vacuuming. The cocoon protects the developing pupa until an adult flea is ready to emerge. That adult flea only comes out of the cocoon when there is a pet (or human) nearby to feed from. When that flea jumps onto your pet, it feeds and 24 hours later, will start to produce eggs, kicking off the lifecycle all over again.

There are a few things you need to take away from this to help you control fleas in your home and on your pet:

  • Killing adult fleas on your pet within 24 hours using a product like FRONTLINE® Spot On or FRONTLINE® Plus is really important so the fleas don’t get the chance to lay eggs.
  • New fleas hatch out all the time and may land on your pet. As long as the fleas are killed within 24 hours, you can still break the cycle.
  • FRONTLINE® Plus has active IGR technology that stops newly-laid flea eggs from hatching and larvae developing in your home.
  • Regular treatment is necessary to get on top of a flea home infestation. It can take up to three months to bring this under control and tackle all the flea life stages in your home.
  • You can also use a household spray which contains an IGR, such as FRONTLINE® HomeGard to kill various flea life stages in the home.
  • It’s much better to treat your pet preventatively, regularly all-year round, than risk an infestation that is harder to control.
