What to look for in good nematodes for fleas

Nematodes are a great way to get rid of fleas in your yard. They are affordable, effective, and they aren’t too hard to find. However, there are many options available on the market today.

And to make sure you get rid of the fleas in your yard, you have to find the best options. To do this, you need to find specific nematodes called “beneficial nematodes”.

Remember, these roundworms are parasites, so the wrong type of nematodes can do more harm than good. So, to prevent you from wasting your money on the wrong type of nematodes, we’ve made a quick guide on the things you have to consider when looking for nematodes for fleas.

Species

First of all, remember that only a specific species of nematodes can effectively kill the flea larvae in your yard. It’s important for you to find Steinernema feltiae (Sf), Steinernemacarpocapsae (Sc) and Heterorhabditis bacteriophora (Hb) nematodes, as these are the ones that are known to help with flea infestations.

But to make it easier for you, these species are usually described under the blanket term “beneficial nematode”. So, just look for packs that have “beneficial” on them and they will likely be able to handle fleas.

Size of the area

Another thing to consider is the size of your yard. If you’re dealing with a significant feal infestation, then you need a large number of nematodes. So, before heading to the market and buying yourself some of these parasites, it’s best to measure out your yard first.

Price

Lastly, nematodes are supposed to be a cost-effective solution. So, you need to make sure that they are priced properly. While you will have to pay a bit more to ensure that you get the right nematodes, you have to make sure you aren’t getting overcharged either.

Beneficial nematodes for fleas

The right type of nematodes that will have a positive effect in removing fleas from your home are known as beneficial nematodes. This is an umbrella term for three specific species of nematodes, these are the Steinernema feltiae (Sf), Steinernemacarpocapsae (Sc) and Heterorhabditis bacteriophora (Hb) species.

If you see any nematodes for sale with these species on them or with the words “beneficial nematode” on the packaging, then these are the types of nematodes that will kill fleas in your yard.

This is because this particular species likes eating fleas. More specifically, they enjoy eating flea larva. So, while they won’t be able to take care of adult fleas that you might find on your pet, they will keep the fleas from multiplying further.

Using nematodes for flea control: What should you know?

Nematodes are living creatures that thrive in soil. With that in mind, they likely won’t be able to thrive in indoor environments. So, if you have an outdoor flea problem, this would likely be the best application for nematodes.

The reason nematodes work well for fleas is that when they feed on the fleas, they get stronger. That way, they can grow and handle larger fleas until they get rid of the problem altogether.

Another cool thing about these nematodes is that you don’t have to worry about maintenance. As long as there are fleas in your yard, the nematodes will eat them and survive.

But once all the fleas are eliminated, it may not be best to keep the nematodes in your yard. Luckily, since beneficial nematodes only eat fleas, once the fleas go away, they will have nothing to eat and will die out.

How do you apply nematodes for fleas?

The best way to apply nematodes for fleas in your backward is by mixing them with water. From there, you can pour the solution onto your yard, and the nematodes will embed themselves in the soil. Different brands have different ratios when it comes to nematodes and water, but you can usually find the appropriate ratios on the packaging.

Additionally, nematodes don’t thrive in warm temperatures and under sunlight. So, if you want to make sure that they get underground and start eating the fleas, then it’s best to apply them to your yard before dawn.

Ideally, it’s best to use a pump or sprayer to pour out the solution. That way, you can ensure equal distribution. However, if none of these tools are available to you, using a watering can works just fine as well.

FAQ

Do nematodes really work for fleas?

Yes, nematodes work well for flea infestations. This is because certain nematodes are known as beneficial nematodes like eating fleas and their larvae. So, if you pour them into the ground, they will feast on the fleas until they no longer become a problem for you at home.

What do professionals use for fleas?

Professionals typically use chemical treatments for fleas. This means that they use a number of different pesticides to kill off the fleas in your home. But if you don’t want to use this method and prefer something more natural, nematodes offer a great solution.

Do beneficial nematodes kill adult fleas?

Typically, beneficial nematodes will only target the flea larvae. So, that means you won’t be able to target the adult fleas on your dog or cat. However, you can use other products that are designed to handle them for instant solutions.

If you combine adult flea killers with nematodes, you get rid of all the fleas currently causing you problems and make sure the younger ones never grow large enough to cause problems in the household.

Final verdict

Nematodes are a great way to treat flea infestations at home. These tiny, microscopic worms are experts when it comes to snacking on flea and other pest larva. That way, once the adults die out, there won’t be a new generation to replace them.

However, if you’re really looking to get rid of fleas at home, you need to get the right nematodes. On this list, we made sure to feature the best nematodes on the market today that is known to be able to kill fleas quickly.
