Lawn Pest Control


Insect infestations can severely damage a lawn, mainly through the consummation of the rootstock. 

The attacks are seasonal and there are a number of ways to deal with the problem. 

This page gives information on a few of the main infestations and how we prevent and deal with any damage.

Chafer Grub

A small white grub with 6 front feet that becomes active late Autumn to early Spring.

Time of year: Around Autumn and Spring when bugs are reaching maturity.

Damage: Messy damaged lawns with areas pulled up by birds and other animals 

Identification: A test is area dug from affected lawn, grubs should be visible. The most damaging  grubs are white and are around 1 to 3 cm. The test area is replaced after examination. 

Prevention: Well maintained lawns are much less susceptible to attacks. Feeding, watering and moss control all play a major part. 

Treatment: Chafer grubs can be controlled non-chemically by the introduction of a pathogenic nematodes, this infects the grub with a bacterium which kills it. They can only be added when the temperature is around 15 -  20ºC.

We can also us a chemical treatment to deal with grub infestations using products not available to the general public. We are fully qualified to use such products and prices can be requested for this specialized treatment. We recommend only to use insecticides if all other methods have been exhausted.  

Any prolonged damage to a lawn can be fixed with dressing and seed in April when the grubs have stopped feed to pupate

Leather Jackets / Crane Flies

The brown / black larvae of the crane fly

Time of year: Can attack from February through to October 

Damage: Yellow and brown patches develop on the lawn and grass begins to die. Usually seen around mid summer.

Identification: If a lot of bird activity is present on the lawn this can be an indication of a high levels of insects larvae in the lawn.

As well as digging a test area to see if the larvae are present, other methods of identification which involve hydrating the lawn and covering it over night to bring the leather jackets to the surface, can be employed. 

Prevention: Preemptive use of pathogenic nematodes in Late September. 

Treatment: Much like Chafer grubs, leatherjackets be controlled non-chemically by the introduction of a pathogenic nematodes, this infects the larvae with a bacterium which kills it. They can only be added when the temperature is around 15 -  20ºC.

We can also us a chemical treatment to deal with most infestations using products not available to the general public.
