|Type of grass- unknown|
Tan colored brown spots.
Grubs assumed to be present because of mole holes in back yard. Brother in law recommended treatment in spring, Memorial Day, mid-summer and Labor day. What do I treat grass with?
|The first sign of grub infestation of your lawn will be the appearance of brown patches. Strips of dead grass will easily peel away as if rolling back a carpet. Brown patches can signify many types of lawn problems, however, so you should test specifically for grubs by cutting out one square foot of turf. If you see five to ten grubs hanging from the roots, the lawn is lightly infested. Thirty to fifty grubs indicate a heavily infested lawn and control should be used to reduce the population. Milky spore and beneficial nematodes are natural grub controls and you can buy both at a garden center. Milky spore is a disease that infects the grubs while they live in the ground and kills them. After it dies, the spore/disease multiplies and continues to spread throughout your lawn. Nematodes are microscopic parasites that attack and devour grubs as well. Both of these treatments are a bit expensive, but one application will keep your lawn healthy for years. Oh, and getting rid of grubs will also rid your lawn of moles, if they're a problem as well. Hope that helps!|
