Are Nematodes Good For Fleas?

While you may be unsure about whether or not nematodes are good for flea control, they do not pose any danger to your pet or other household pets. Besides, millions of nematodes already live in your garden soil and will increase in number in times of flea infestation. You can even use nematodes in your normal gardening activities without worrying about their presence or safety.

Nematodes work by attacking the flea larvae. It takes at least a day for them to do their work. Once they find a flea to infect, they will remain on the flea for at least 48 hours. However, it takes at least two weeks for the nematodes to make a noticeable dent in the flea population.

Nematodes are beneficial because they can kill off the larvae of fleas and other pests in the soil. They are also beneficial in the control of white flies, fire ants, and grubs in the soil. Although many people mistakenly think that they have gotten rid of their flea problem, the problem can return within a few weeks if the nematodes do not die off.

It is best to buy nematodes from a reputable source and use them as soon as they are delivered. They will expire if stored at room temperature for more than two weeks.
