Nematodes are tiny, worm-like creatures that are barely visible to the naked eye. They are often no larger than 0.1 to 1 millimeter and have a translucent, elongated, segmentless body, making them appear somewhat slimy under a microscope.
What makes them special is that some species have a sharp, piercing proboscis to penetrate plant roots or insect larvae. Fortunately, beneficial nematodes only use this ability to control pests like grubs and snails !
They move through a thin layer of water in the soil, searching for their prey or a suitable breeding ground. Once they penetrate an insect larva, they release bacteria that kill and break down the larva, allowing the nematodes to feed on it. After a few days, new nematodes are released, ready to continue their hunt. This way, they naturally help control insect pests in your garden!
