Grub activity is increasing along the Front Range. We are seeing established infestations in Greeley, Johnstown, Windsor and Fort Collins. Grubs cause damage from late spring through the end of the growing season depending on which type they are. Grubs eat the roots of your grass, causing damage. Grubs also attract raccoons, skunks and even birds dig up the grass to feed on them. The animals can cause even more damage than the actual grubs! If you see holes like something has been digging in your lawn, peel back the grass near the damaged areas. It usually pulls back far too easily because the grubs have been eating off the roots and just pulling with your hands can pull back a section of grass to look for grubs. If grubs are discovered in your lawn, an insecticide will need to be applied to control them. Please leave such applications to professionals since proper identification of the grub, which product to use, timing and proper application methods are important to get control.
