A lush, green lawn sends a message to your neighbors that you know what you are doing when it comes to lawn care. Your home has the perfect curb appeal when it is looking healthy and vibrant, and it is an insult to your gardening skills that it is daring to go brown and look less than lush! However, it may not be your gardening prowess that is at fault here. There are two annoying lawn pests that could be to blame, and these are the facts you need to know.
Billbugs are beetles that love to attack the roots of any type of grass. There are two main indicators that billbugs have attacked your lawn:
- The brown patch of grass is not recovering, despite being watered repeatedly.
- When you tug at the grass, it comes up easily in your hands. This is because the billbugs have eaten away the roots holding the grass in place.
Billbug damage starts off small with little brown patches here and there, but this will spread into larger patches as their larvae hatch and also begin to feed on more of the grass roots. Billbugs leave a white residue behind that looks like fine sawdust on the soil surface.
The bad news is that because of the thickness of the billbug's body, insecticides do not work effectively, as they can't penetrate into the bug. The best way to fight back against the billbug is to increase your watering and fertilizing regime. This will encourage fresh lawn growth, and that will minimize the impact made by the billbug.
White grubs are another pest that has a fondness for grass roots. While they will attack any type of grass, they are particularly in love with bluegrass and ryegrass. When they move into your lawn, you will see brown patches of dying grass. If there are a lot of white grubs in residence, your lawn may even begin to roll away backwards from the dirt.
White grubs look like fat, "C" shaped worms and can be found close to the surface if you look at the damaged area. Increasing your watering and fertilization of the lawn will help to keep it in a healthy state to fight back against the grubs. However, if these increases do not improve the state of your lawn, you will need to use an insecticide to kill the pests.
Now that you know what to look for in your damaged lawn, it is time to head outside and find out what is causing your lawn woes. Once you know for sure that billbugs or white grubs have moved in, head to your gardening center to buy some heavy duty lawn fertilizer so you can get your grass into a super strong state. Then it can fight back, and your bugs will move out. For more advice, speak to experts like Collins Lawn/Insect Control.
