Adult fleas may be jumping around and biting you, but killing them is not going to stop an infestation. You need to target the root of the flea problem, which is the flea eggs and larvae. However, killing flea eggs and larvae can be difficult. This is because there are so many of them, and they are extremely small, making them hard to see.
Here we will go over everything you need to know about killing flea eggs and larvae in your house.
Why Killing Flea Eggs and Larvae is Important
Why is it so essential to kill the flea eggs and larvae? Well, they make up the bulk of any flea infestation. If your house is infested with fleas, only around 5% of the fleas are adults. The other 95% are flea eggs (50%), flea larvae (35%), and flea pupae (10%). So, killing the adult fleas will not do much to eliminate the infestation. You need to kill the eggs and larvae, or else they will eventually hatch into adults. Then they will lay more eggs, and the infestation will continue to thrive.
Killing the flea eggs, larvae, and cocoons should be more of a priority than killing the adults. However, killing adult fleas is still important. Adults can lay 50 eggs a day, and they will bite us, leaving behind itchy welts. Using flea traps is a great way to capture and kill adult fleas.
Where Flea Eggs and Larvae and Found in Homes
If you want to the kill the flea eggs and larvae, you need to know where they are found in homes. Luckily, they are usually concentrated to a few prime areas, making them easier to find and kill. The most common place where young fleas are found is in carpets and rugs. Carpeting provides protection, camouflage, and an unlimited food source for flea larvae.
The adult female fleas will lay their eggs in the protective covering of carpet fibers. Then the larvae will hatch and feed on blood droppings left behind by the female adults, along with organic debris. Eventually the larvae will spin cocoons that pick up debris, making them blend in well to carpeting. While carpets are the most common places to find baby fleas, there are are few other places that might be infested. They are:
- Pet bedding
- Pet kennels
- Dog & cat fur
- Human hair
In the backyard, the larvae will likely be found in places where your pet likes to rest. Other common outdoor locations are under boards, behind flower pots, and in dark areas. They like dark, moist, and shaded locations.
