From time to time, particularly in the autumn months, your healthy lawn can fall victim to an insect infestation of chafer grubs or leatherjackets. These two common species of garden pests can wreak havoc on your lawn by attacking the grass root or encouraging predators such as birds, badgers and foxes to dig for grubs. This isn’t uncommon or abnormal, which is why we at Greensleeves Lawncare have specialist treatments to tackle the problem. We offer a range of specialist lawn insecticide treatments that can help eradicate lawn pests and insects.
At Greensleeves, we believe it is essential to take action at the earliest opportunity, so we would highly recommend our Biological Insect Control (also known as nematodes) treatment to be applied in the late summer or autumn for the best results.
If you think you have an insect infestation of chafer grubs or leatherjackets, you will need an effective lawn insecticide treatment as soon as possible to prevent any further lawn damage. Get in touch with Greensleeves today on 0808 100 1413 for help and advice.
What are nematodes?
Nematodes are 100% organic and will, over time, combat the pest infestation while causing no harm to the grass itself. Our treatment consists of tiny organisms which naturally occur in the soil already at minor levels, and are extremely effective in killing targeted garden pests.
These minuscule predators will go in search of the grubs or leatherjackets by attacking and inoculating their bodies with bacteria, often while the pests are in the infective juvenile stage of maturity. Once the nematodes have taken control and exterminated the pests, they too will die off and return to the natural number count within the soil.
The insects in your lawn.
The most common insect infestation we see on British lawns are chafer grubs (phyllopertha horticola). They are the larvae of the cockchafer beetle and leatherjackets (tipula spp) which is the larval stage of the crane fly or daddy long legs.
The application of lawn insecticide UK.
This specialist treatment can only be used in the right conditions. The soil temperature must be above 12 degrees, so application is recommended between July and October. The soil must also be moist in order for the nematodes to survive once applied.
In preparation for the application, the lawn should be mowed and spiked to ensure that the nematodes have maximum opportunity to reach the pests inhabiting the top layer of the soil. The nematodes will be mixed with water and applied to the lawn using a backpack sprayer.
The first step before commencing with the lawn insecticide treatment is to correctly identify what problem specifically your lawn is suffering from. Once this is determined, your local lawn expert can then decide the correct course of action.
With chafer grubs, we can apply an effective lawn insecticide that uses Nematodes, a form of Biological Insect Control. For the best results, this should be carried out between July and October.
How it works.
After the treatment has been completed by your lawn care expert, the lawn will need to be watered and continue to be lightly irrigated for the following 2 weeks to maintain a damp soil profile. During this time, the nematodes will target and inoculate the bodies of their hosts causing them to stop feeding and ultimately die. The nematodes then reproduce to create a further generation to continue with the task.
What can I expect from grass insecticide?
You can expect effective treatment that will control and kill the pests on your lawn. However, it’s important to note that while it is often simple to eradicate pests once they have been correctly diagnosed, it is more difficult to prevent them from returning. The insects will sometimes lay their eggs on your lawn the following year too. It is important therefore to follow a turf maintenance program to ensure your lawn is in the best health possible, which can help to minimise risk of these issues. Your lawn manager will be happy to discuss this with you.
How do I know if I need insecticide for lawns?
If you have a chafer grub infestation in your lawn, you’ll be able to see the grubs just below the surface after a quick visual check. Leatherjackets are a little trickier to spot than chafer grubs, as when the grubs are evident in your lawn, it may be too late to treat, as they need catching in the very early stages of maturity. Look out for crane flies, as they will indicate the laying of their eggs which will eventually become leatherjackets.
