Obtaining a lush green lawn is the goal of many homeowners, but isn’t something that is always easy to achieve. It can seem as though you are constantly fighting the elements such as getting enough sun, not getting enough sun, keeping it cut at the best length, controlling weeds, making sure the lawn is adequately watered, and of course dealing with pests. Pests can be one of the most destructive things for your lawn, destroying all your hard work in a rather short time. While a number of different pests can be to blame, grubs are among the most common.
So, how can you tell if you have grubs or not, should you do anything about it, and what can you do to get rid of them? Let’s take a closer look.
How to Know if You Have Grubs
Before you go ahead and come up with an action plan to deal with grubs, you need to first find out if you have a grub problem. The best way to check for grubs is to take a look at your lawn and identify any bare or brown spots. Next, you want to peel back the turf in one of these areas and look at the soil. The grubs will look like tiny white worms and will be easy to spot when you peel back the turf.
Grubs actually eat the root of the grass, which is why you’ll see it turning brown then bare. As well, there are a number of animals that dig for grubs and eat them, which will further destroy the grass. A grub problem can escalate very quickly if you don’t take quick action. What this means is that you don’t want to just ignore the problem. Grubs won’t just clear up on their own, and if you’re not careful you can end up losing your whole lawn. They can be quite difficult to deal with, so the earlier the better.
How to Get Rid of Grubs
There are a few different methods that you can use in order to deal with your grub problem. If you like the natural route then you can treat your lawn with nematodes. These are live microscopic parasites that work by getting into the body of the grubs and infecting them with bacteria that ends up killing them.
Another way to get rid of them is to let your lawn dry out as much as possible, as this will make it impossible for grubs to survive and thrive. Ideally, you want to let your lawn dry out for three to four weeks during the summer months. Not only will this kill the current grubs and their eggs, but it will decrease how many you have the following year.
Chemicals can also be used to kill the grubs if you choose. As for the best time to treat for grubs, late summer to early fall is typically the most effective time to treat for them.
Leaving the grubs and not taking any action will only leave you with a mess of a lawn that will take a lot of time, money, and energy to bring back.
