How Can You Tell if You Have Insects in Your Lawn?

predetors help control lawn grubsBefore you treat your lawn for insects, you want to make sure you have a high enough population of insects or grubs to damage your lawn.   Having insects or grubs in lawn is natural, but too many are devastating. They can take a nice looking lawn and in a matter of weeks, they can completely destroy it.

It is best  to recognize what some of the signs are. One sign is if your grass starts to turn yellow for no clear reason. If your lawn is getting plenty of water and sunlight, as well as fertilizers, and your grass still turns yellow you probably have a problem with insects. This can either be a fungus or insect infestation. One thing that is notable about insects, is that they will destroy the roots first, so if this is the case, the grass should rip out of the lawn easily.  Most of the time insects are pretty easy enough to kill, as long as you catch them early and you put down enough poison when you are trying to kill them.

When is the Best Time to Treat Lawns for Insects?

The best time to treat your lawn for insects depends on which part of the country you live in.  We want to help you know when to treat your lawn for insects. Most of the damage done by lawn grubs is in the middle of the summer. If you’re going to treat your lawn, you want to do it earlier. Most people will treat their lawn in the  the late spring, or the early summer. This is the best time to use grub killer to kill grubs that are in your lawn.  Japanese beetles are an exception because the best time to treat them is in the fall.

What types of lawn grub control are the best?

I have always preferred to use the granular applications. This is because it goes directly on the plant and can also be absorbed into the grass plant. As the grubs grow, they eat the grass plants and the roots. The systematic grub killer works well to kill them as they eat these plants.

The Life Cycle of Grubs in Your Lawn

If you are suffering from grubs in your lawn, before you can know how to treat them, it is important to understand their life cycle Most of the time these grubs in lawn are the larva of lawn beetles. They can also be the larva of crane flies. The most common kind of lawn beetles, are Japanese beetles, June beetles, and Chafer beetles. Lawn beetles will hatch in the early spring. Then they will find a new lawn to lay their eggs in. In a month, their eggs will hatch. They emerge, not as beetles, but they will be small larva. This larva will continue to get bigger throughout the spring and the summer, as they eat your grass and your grass-roots. In the fall, the grubs will burrow themselves deep into your lawn. Four or five months later in the spring, they will emerge as beetles and the life cycle will repeat itself. The time in their life cycle, where it is easiest to kill these grubs, is when they are larva and they are actively feeding on your lawn.

How to Prevent Grub Worms in Your Lawn

While there is no way to prevent grubs from coming into your lawn, there are some things you can do to prevent grub worms from damaging your lawn. One of the things that you can do to help prevent grubs is to have a good healthy lawn to begin with. Since grubs live below the surface of the soil and they eat the roots out of your grass, then you need to make sure that your grass and your grassroots are as healthy as possible. This way when you do have grubs, they won’t do a lot of damage. Often the damage they do won’t even be noticeable.

how to prevent grub wormsIf you want to have a healthy lawn, you need to do the four following things. First of all, you need to make sure that you water your lawn regularly. It actually works better if you water it less often, but water deeper every time that you do water. In order to encourage the roots to develop deeper, it is also a good idea to aerate your lawn. By using a lawn aerator, you will have thicker turf that will be more resistant to grub worms. The third thing that you need to do is to make sure to fertilize your lawn . Most lawns thrive when they get fertilized. Try and fertilize your lawn at least four times per year. Usually this means fertilizing it every 6 to 8 weeks during the season where it is growing the fastest. Adding fertilizer in July will also help you develop a thicker turf.

how to prevent grubsThe last thing you need to do is to mow your lawn and never mow up more than 30% of the blade. The reason is if you mow your grass too short, then your turf actually shrinks. If you mow your grass too long, then your grass becomes sparse because there’s too much grass competing for sunlight. If you want to keep a dense healthy turf both above the ground and below it, you want to make sure to keep your grass at an ideal height. If you use these four methods, you should have no trouble preventing grubs in lawn from doing major damage to your grass.

lawn grub beetlesLawns are the ideal place for some grubs to live. They have access to lots of food and water and they don’t even have to travel very far to get it. White lawn grubs are typically beetle larvae living in the soil that eat the roots of your grass lawn. White grubs typically turn into beetles, because other forms of grubs, such as cutworms, and army worms turn into moths. The larvae stage is for more damaging than the adult stage. The early larvae stage is the best time to control or get rid of white grubs.

The best time to kill or control larvae is when they are actively growing during the late spring and early summer. During the winter, grubs may have burrowed themselves deep into the soil and be unaffected by pesticide. It is good to use a long-lasting pesticide to control white grubs. This kind of pesticide is more effective because it can kill multiple generations during the same time period. I am also doing research on nematodes as a more natural way to control lawn grubs. Sometimes multiple pesticide applications are necessary to kill white grubs.

Control Cutworm Problems in your Lawn

Cutworms are usually brown or tan color and they have a few stripes that run down their middle. In the fall they turn into dark months. These insects are mostly nocturnal. They come out at night to eat your lawn. They are 1 to 2 inches in length.

How do I control cutworms?

Fortunately cutworms are very easy to control and get rid of. Most contact herbicides will help kill them.

How to Rid Your Lawn of White Grubs

Why White Grubs Are a Lawn Pest

white grubsBeetle larvae that are small (1/2-1 inch long) and white are collectively known as “white grubs.” The worse pests include the Asiatic, June and Japanese beetles as well as masked chafers. Starting in spring as newly hatched larvae, they eat the grass roots of the lawn, decreasing the turf’s tolerance to minor drought, heat and other stresses. The grubs do not kill the grass themselves, but create wilted and dry patches that can eventually lead to the plants dying off.

When Grubs Do the Most Damage?

White grubs are actively growing through the spring and summer months, so that is when they do most of the worst damage to the lawn and that is the best time to apply pesticide. As fall arrives, they dig deeper into the ground, spending the winter around 8 inches below the surface. This means that pesticides applied in the fall and winter may not get down to where the grubs are. When spring arrives again, they will be adult beetles that will each lay many eggs of their own, increasing the infestation problem.

How to Spot a White Grub Infestation

Grubs are small and tend to stay in the thatch layer of the lawn. It is hard to know that they are there. Look for: 1) dry and wilted grass patches,2) shallow turf that easily comes up, and 3) gophers or birds creating lots of holes in the lawn as they try to find the grubs to eat.

How to Treat for Grubs

Apply a long-lasting pesticide as soon as you notice signs of a white grub problem. The earlier you start treating it, the easier it will be to rid the lawn of them. Often the pesticide will need multiple application through the spring and summer to thoroughly treat the pest problem.
