Chafer Grubs are the larvae of the Chafer Beetle. Chafer Beetles are insects that live in the soil in May/June during the day and emerge from the soil at night, fly to nearby trees and shrubs in swarms to mate then return to soil at dawn. The female beetle lays eggs in the soil which take about 2 weeks to hatch usually about late July. When the soil is damp, they move closer to the surface to eat the roots of the grass (which causes damage to the lawn) and when it is drier they move lower down into the soil and don’t feed so the amount of damage they do to the lawn at that time of year depends on the moisture levels in the soil. They usually feed until the end of September and when it starts becoming colder in October they move lower down into the soil for the winter and stop feeding, only moving higher to feed when the weather is warm enough. They then move closer to the surface again in spring when they feed heavily on the roots of the grass and this is when they cause the most damage.
The signs of damage are very much the same as Leather Jackets, i.e. brown, dead or dying patches of grass, lots of birds pecking at the lawn (searching for Chafer Grubs to eat), parts of the lawn that seem to of been pulled up by birds or other animals again searching for Chafer Grubs to eat. On some lawns the turf can be rolled back like a carpet and the grubs might be found underneath.
Like Leather Jackets, Chafer Grubs can cause damage from just a small patch to the destruction of an entire lawn. They usually feed until May or June when they move deeper into the soil again to pupate into adult Chafer Beetles in June when they emerge out of the soil at night and fly to nearby trees and shrubs to mate and so the life cycle starts again.
Lawnsavers Lawn Treatment Services can eradicate Chafer Grubs from the lawn by applying one or two treatments of insecticide during the year which will eradicate the Chafer Grubs and stop any further damage to the lawn, which will start to recover from any damage already done. However in cases of severe damage, the lawn or parts of it might need to be re-seeded or turfed, which Lawnsavers Lawn Treatment Services can give you advice about at the time.
Certain species of Chafer Grubs have a life span of 2-3 years before they pupate into adult Chafer Beetles so the larvae (Chafer Grubs) could be found any time of the year but usually higher populations in the spring.
Chafer Grubs belong to the same family as the Scarab Beetle.
In the United Kingdom there are 5 different species of Chafer Beetle:
The Summer Chafer, Welsh Chafer, Garden Chafer, Brown Chafer and Rose Chafer.
The most commonly-found Chafer Beetles are the Welsh Chafer and the Garden Chafer, with the welsh Chafer being the most common in sandy soils.
