Grub feeding leaves irregular brown patches and the lawn may have a spongy feel. Sod will roll up like loose carpet if the roots are already destroyed. The only way to know for sure, though, is to gently pull up a small section of sod. If you see more than four grubs per square foot, you have a problem. Lawns with severe grubs can have 40 - 60 per square foot.
New treatment can stop grubs before they begin.
The treatment is applied to soil and is taken up by plant roots. It doesn't harm the grass, you, or other plants, but it turns your lawn itself into a deadly choice for hungry grubs. Timing is everything Unlike other treatments, this one must be applied weeks before grubs are active, so grass plants have time to take it in. If you miss the timing, standard applications still work, but if you suspect you may have grubs, or have questions about treatments, email us. We love giving grubs a grand good-bye.
