What do fleas look like? Adult fleas are about the size of a grain of rice and have long hind legs that they use to jump. They also have a hard, flat body covered in tiny hairs. Flea’s eggs are white and about the size of a dust particle.

Flea larvae are small, worm-like creatures that hatch from flea eggs. They are white or light brown and have no legs. Flea larvae live in dirt and debris, where they feed on flea eggs, skin cells, and other organic matter.

Pupae are the last stage before fleas become adults. Pupae are cocoons that fleas build around themselves. They are light brown and about the size of a pinhead.

Inside the pupae, fleas develop into adults and emerge when they are ready to mate.

How can you get rid of fleas on your deck naturally

If you have fleas on your deck, there are a few things you can do to try to get rid of them.

Boric Acid

Boric acid is a natural flea killer. You can buy it online or at most hardware stores. Make a boric acid powder by mixing one part boric acid with three parts flour.

Sprinkle the powder on your deck and around areas where fleas are likely to congregate, such as in cracks or crevices. Reapply the powder every few days until the fleas are gone.

Diatomaceous Earth

Diatomaceous earth is another natural flea killer. It works by dehydrating the fleas. You can buy diatomaceous earth online or at most hardware stores.

Sprinkle the powder on your deck and around areas where fleas are likely to congregate. Same as Boric Acid, reapply the powder every few days until the fleas are gone.

Soap and Water

One of the most common and effective ways to get rid of fleas is simply washing them away with soap and water. This will remove the fleas from your deck, but it will also kill any eggs that may be present.


Fleas hate vinegar. Make a spray with vinegar and water and spray directly onto fleas and areas where you have noticed fleas on your deck.

Light Traps

One of the most effective ways to get rid of fleas is to use light traps. These devices attract fleas with a heat lamp and trap them on a sticky pad.

You can purchase light traps at most hardware stores or online. Be sure to place the traps in areas where fleas are most active, such as near your pet’s bedding or in areas where your pet spends a lot of time.

Check the traps regularly and dispose of the fleas.

You should not use light traps if there is a danger of the device getting wet!
