Say Goodbye To Those Grubs!

Let’s be honest. Besides the fact that they damage your lawn by eating grass roots, grubs just generally have a pretty high ‘ick’ factor.

When grubs feed on the roots, your grass will start to die. If you’re noticing brown patches on your lawn that can easily be peeled away from the soil (like lifting back a rug), then it’s time to take a closer look. Dig up a few small sections of your lawn. If you’re finding more than five grubs in about a quarter of a square foot area, it’s time to take action.

The best time of year to treat your lawn for grubs is late summer to early fall. This is when the grubs are small and close to the surface.

There are several natural solutions that will take care of these little white pests.

Beneficial nematodes are tiny worms that live in soil. They release bacteria into the soil. These bacteria infect and kill lawn grubs. They are available in liquid form or you can mix them with water and spray them onto your lawn.

Another product you can mix with water to spray on your lawn is neem oil. It’s a botanical pesticide, and it works as a repellant, inhibiting egg laying, growing and feeding.

Finally, you can try milky spore, which infects the grubs as they feed. The grubs will die and decompose, which releases additional spores into the soil. This helps prevent further infestations.

Now, you might not have a grub problem, and want to keep it that way. The best thing to do is to make sure your lawn is as healthy as possible.


Overseed your lawn to make sure the turf is nice and thick. This will discourage grubs. Also, don’t overwater your lawn. Grub eggs need moisture to hatch. The added bonus to this is, if you don’t over-water your lawn, the grass roots have to go down deeper into the soil to find moisture, making them stronger and more drought tolerant.

You can also apply topsoil to your lawn, to really help it grow healthy and thick. We recommend BigYellowBag Black Garden Soil. It’s proven to help your lawn grow thicker and healthier, even if that’s the only thing you add to your turf.
