Fleas in Houses | Cat Flea, Dog Flea and Human Flea
Although fleas can be a problem throughout the year they are more prevalent in the Summer and Autumn. Fleas in houses can increase during this period due to several reasons. First fleas are not active outside during the Winter, Spring and late Autumn. During the warmer weather they will survive outside and hedgehog fleas, rabbits and rats. These will be several different species to the flea normally present in houses which even on dogs is the Cat Flea.
The Cat flea has taken over from the Dog flea and the Human Flea (the human flea is the type of flea used in the Victorian ‘Flea Circus’s’). Fleas also do not live on the host animal, they go on to feed and may stay some time on the host but generally will live in carpets, bedding or vegetation and then feed once the host animal passes by. Cats and dogs are animals of habit and will often have a comfortable resting place outside where fleas will rest and then feed when the animal arrives. Due to this outside activity most cats will encounter fleas in the Summer and bring them back to the house. In most cases the fleas will not bother humans and the act of hoovering, lawn cutting and treatments such as Program or Tigivon will keep flea numbers so low that humans are not bothered.
What upsets this is when the cat is away for any period. This may be because the weather is nice so the cat spends more time outside so the fleas living in the carpet of the house get hungry and feed on people or it may be that the flea numbers in the house have increased to a level that is uncomfortable for the cat so it avoids the infested areas and stays outside. If fleas are hungry they do two things, first they will feed from animals that are not their usual host and secondly move around looking for the host animal. Once they have reached this stage the only option is to treat.
