Can Fleas Get Out of a Vacuum?
Vacuuming your carpets and pets regularly is a good way to get rid of fleas. This is especially useful for pre-adult fleas that have not yet hatched. The pre-adult fleas consist of the eggs laid by female fleas on your pets. The eggs are easy to vacuum up and will hatch into larvae in about two to three days. If you notice a large number of flea eggs in your carpet or on your pet, you should make a special effort to vacuum up these eggs.
The best way to remove fleas from your home is by using a good vacuum cleaner with upholstery attachment. Make sure to vacuum every inch of furniture, including the undersides. Then repeat the vacuuming process daily. This method will not get rid of all fleas, because leftover unhatched eggs and larvae will continue to develop.
Adult fleas emerge from their cocoons when they sense a human host nearby. This happens due to a combination of heat and pressure. Once they emerge, they must feed on the host within a week. In the meantime, cocooned flea pupae develop and survive dry conditions. They also survive immersion in water. Unlike larvae and eggs, cocoons are difficult to vacuum up.
Flea eggs are not hard to vacuum. They are microscopic. Their size is about one-fifth the size of a grain of salt. Hence, if you vacuum your carpets regularly, you will eliminate 90% of the eggs in your carpets.
