    How Long Does it Take Grubs to Destroy Your Lawn

    Posted by: Robert Palmer on April 9, 2013

    lawn grubSometimes, no matter how well you water and fertilize your lawn, you still get dead, brown spots. If this is the case, your lawn might be experiencing a grub infestation, which can do considerable damage if you let the grubs continue to grow and feast unchecked. How long does it take grubs to destroy your lawn? To help you understand how grubs infest and kill once-healthy lawns, here's a brief summary of the grub life cycle.

    In early spring, mature grubs wake up from their hibernation and dig themselves up from deep in the soil to just below the surface of the grass. They change from a pupae stage into beetles, which feed on your trees, shrubs, and roses.

    Well fed on your landscaping, the beetles burrow back into your lawn and lay eggs, producing the next generation of grubs.

    As the weather begins to cool, newly hatched grubs gain strength by eating your lawn's roots. These nutrient-rich roots give them the energy stores necessary for hibernation over the winter. Unfortunately, your lawn withers away as its root system is destroyed.

    What can be done to stop the cycle of destruction that grubs inflict on your lawn? And when should you pay attention to possible grub damage?

    Waiting until you see brown spots in your lawn is not a good way to handle grubs. By the time your grass begins dying, the root system has been severely damaged. Even before the grass turns brown, you may notice that some areas of your lawn feel spongy when you walk on them. Usually, when a lawn turns spongy, the root system is so damaged that you can peel back the turf like you'd peel back a piece of carpet.

    Another way to tell if you have grub damage is to observe the wildlife in your yard. Moles, skunks, raccoons, and robins love to feast on grubs, so if you see these animals digging or nosing around in your grass, it's wise to suspect a grub infestation.

    Fortunately, we have the knowledge and tools necessary to prevent and treat grub damage in residential lawns. Of course, it's always best to preventgrub damage in the first place, so we offer this service as part of our Basic and Deluxe Care Packages. In addition, we offer optional grub treatment as a separate service for customers who desire a more personalized plan.

    Last year's drought was hard on lawns. Since the moisture level was low last summer, grubs stayed around a little longer than usual, causing more damage than usual. Lawns need a little extra care this year to make up for last year's harsh conditions. If spots of your lawn were destroyed by grubs last year, it's time to re-seed or re-sod those areas.
