One of the best ways to protect your lawn from grub damaging insects is through a grub control application. This preventative application will greatly minimize the chances of grub damage to your property. If you have not experienced grub damage in your lawn before, then you might not be aware of the devastating damage that grubs can do in a short amount of time. In Iowa most grub damage is noticed from mid July to the beginning of September. Grub damage is easy to identify. The most common things to watch out for are patchy lawn browning, grass being able to be rolled back like carpet and noticeable critter activity. If you have a well irrigated lawn, you may not notice any lawn browning since the grass has adequate access to water. You will still notice grass coming out in large chunks or critter activity. Since grubs feed on the root system of the grass plant, the sod in your lawn will lose its stabilization. The sod will no longer be rooted into the soil, because the deep roots have been eaten off. Having a grub control application applied to your yard in June or July will stop these pests from damaging your lawn.
Your Grub Control Application must be watered.
In order for the grub control preventative products to work property, they need to be watered in. Watering after the grub control application helps activate the ingredients and helps them work their way into the soil where grubs are found. Always read your product label prior to applying it and follow the instructions as directed. Hiring a professional contractor to provide this service can take the guess work out of the application and make it more effective.
If you choose not to protect your lawn with a grub control preventative, you still have some options. Post emergent products can be used to control grubs once damage is noticed. Waiting until there is visible damage will end up costing you more in the long run, so consider grub control preventative applications an insurance policy for your lawn.
