Beneficial Nematodes For Termtites: Are They Really Effective?

Termites are stubborn, and it’s difficult to get rid of them. Among dozens of extermination methods, nematodes for termites have proven to be one of the safest and the most effective ones.

Stay tuned, as we’ll talk more about them in the next couple of paragraphs.

What Are Beneficial Nematodes?

nematodeNematodes, more commonly known as roundworms, are microscopic animals that can easily adapt to any ecosystem they’re in. They can be found anywhere in the world, from the top of Mount Everest to the lowest point of the Pacific ocean.

The nematode stomach contains bacteria that are lethal for many insects, including termites. When ingested, the nematodes release the bacteria inside of the bug. The bacteria then multiply and poison the blood, leading to inevitable death in 24 to 48 hours. The body of the bug then turns into food for them, enabling them to feed until it’s completely gone. When that happens, the nematodes immediately start looking for the next host.

These parasitic creatures are deadly, which is why they’re often used as a method for killing termites. But how beneficial are they really?

The nematode method is 100% natural and non-toxic, which is a major advantage over the strong chemicals that pesticide companies sell. It’s definitely worth giving it a shot, even if it doesn’t work on the first try.

Not only are nematodes for termites beneficial, but they are probably the most effective natural termite extermination method of all time.

Side Effects of Beneficial Nematodes

To be honest, there aren’t any side effects of using beneficial nematodes for termite control. The nematodes are natural — they aren’t toxic for humans or animals, nor do they destroy your home in any way.

However, you still need to be quite careful when handling them. There is a small chance of humans or animals contracting nematodes. Although it’s highly unlikely, we should be aware of this possibility.

Follow the instructions carefully and double-check everything. Also, make sure you’ve acquired the right nematodes. I suggest consulting a specialist before doing anything yourself.

According to the EPA, nematodes have proven to be effective in lab settings. If applied correctly, they can be the ideal solution. Unlike termite bombs and foggers, the beneficial nematodes can potentially get rid of termites forever, killing off both their surface colonies and the hidden nests.

And not just that — nematodes for termites act quickly. Once they enter the termite’s body and spread the bacteria, the termite will be dead in 1 to 2 days. After they’re done feeding with that one, they’ll move on to the next, until all of them are gone.

How to Use and Store Nematodes?


Every beneficial nematode packaging has its own instructions, which you should follow to the letter.

Be that as it may, the most common way to apply them is by mixing them with water and spraying them onto the affected areas in and around the house.

Use a large container to mix the two and let it sit for an hour or so. After that, you can pour the mixture into the spraying bottle and start spraying everywhere you’ve seen a termite. Start with the yard, because that’s usually where termites start spreading.

Do so every day for about 2 weeks to get the best results. Avoid using fertilizers during this period.

’‘How long do beneficial nematodes for termites live?’ and ’‘How do I store them?’, you may ask.

They live for around 30 days, as long as you store them in a cold and dark place. You can keep nematodes in the fridge (not the water mixture). However, do not put them in the freezer.
