Do you have pets? Do you have a yard? Do you try to stay organic? If you answered yes, you need to know about beneficial nematodes because they’ve got your back. They will solve your flea and tick problem without having to resort to toxic pesticides.

Toxic pesticides kill all the beneficial critters like ladybugs and earthworms. Products like Roundup and Weed & Feed do more damage than good. If you lose your earthworms you lose your soil aeration. Lose your ladybugs and praying mantis and you’ll have to buy more toxic chemicals to control pests.

What are Beneficial Nematodes and How do They Work?

In a nutshell, they are non-segmented, microscopic roundworms. You might not have heard of them but they occur naturally all over the world. Well, perhaps not Antarctica.

They are predators of tick and flea larvae in the soil. These may be your primary concerns but they also control sod webworms, cutworms, maggots, various types of ants and many more. They work by first finding a suitable host.

Next they enter through an appropriate body opening or through the body wall. Once they have taken up residence they produce a bacteria and inject it int the host’s blood, which kills the host. Finally the search for the next host begins.

How are they Applied to Your Lawn?

Since the nematodes arrive at your home in a seemingly powder form, they can easily be applied in a variety of ways. Small areas can be applied with a watering can.  Large lawns are candidates for hose-end sprayers like the one I used this morning. It’s a good deal since it comes with  loaded with fertilizer.

You won’t likely find nematodes at your local store but they are easy to find on-line. Every spring I order mine from Arbico Organics. High-quality products and quick delivery. For my front and back yard I order the 10 million size (rated for 3,200 square feet). A bit of overkill perhaps, but after the flood from Hurricane Harvey who knows what’s lurking below the soil?
