Essentially, the problem with fleas is that they combine several horrible qualities in a single annoying insect. Because they hitch rides on the backs of cats and dogs, they tend to spread to the most distant corners of your home. Because they’re so unpredictable and independent, they can’t be killed with bait like ants sometimes can. And on top of all that, they bite humans whenever they get the chance.

Although you can try to deal with fleas yourself, it’s a difficult and frustrating task. First, you need to methodically wash and dry every item of clothing or furniture that might be harbouring them. Then you need to vacuum every inch of the infested room. Flea powder and flea bombs can be quite effective at killing fleas, but unless you have professional expertise, they’re dangerous for pets and children – and more often than not, some fleas will escape to bite you another day.
