Full Answer

Grub worms are the larvae of various beetles, such as the Japanese beetle and masked chafer. They form cocoons in June and emerge in August as full grown beetles. Grub worms not only damage the lawn but invite other unwelcome wildlife to the area. Late summer to early fall is the time most damage occurs and the best time for treatment. Grub worms cut off grass plant roots, making the grass more susceptible to lack of rain. Visible brown patches are the first sign of grub worm infestation.

Grub worms are smaller and closer to the surface during the fall. This is when they do most of their damage and is also the best time to apply treatment. Dylox is the most effective insecticide for treatment during this period, killing the pests before they can lay their eggs and addressing the problem of any hatchlings.

Natural methods work both as repellents and as treatments. Natural treatments are environmentally safe and generally less expensive than purchased pesticides.

    What do worms eat?

    A:

    The diet of a worm is based off its location, but worms traditionally eat everything from dead leaves to melon rinds and even cardboard. Studies show that worms are one of the only creatures on the planet that use just about all solid waste as their main diet. This is why many environmentalists believe that worms have the ability to save the planet. They suggest that worms be added to landfills to help eat the waste before it builds up.
