Bayer Garden has developed a truly effective lawn grub control, Provado Lawn Grub Killer. Formulated as a simple-to-use, water-on, systemic insecticide, you can now ensure that your lawn remains free from the disfiguring die-back caused by these insidious lawn grubs.

Provado Lawn Grub Killer is so easy to use and garden friendly that once dry, the treated areas may be used immediately by children and pets.

Stop them before they start!

Provado Lawn Grub Killer is best used as a preventative control. Once patches or yellowing and browning of the lawn is apparent, much of the damage has already been done. However, if applied at the right time of year, one treatment is sufficient for year-round protection from both species of lawn grub.

If you have obvious signs of damage already, do not despair! You can stop these destructive insects in their tracks by applying Provado Lawn Grub Killer. They will stop feeding immediately the treatment is applied. The product will prevent further infestation. In areas of severe damage, re-seeding and watering to aid recovery is recommended.

ONE TREATMENT PER SEASON CONTROLS BOTH OF THESE PESTS

Are you getting yellowing, browning or dead patches on your precious lawn?

Your first thoughts may be to blame the kids, the pets or lack of rain. But the most likely culprits may be hidden - you could have Leatherjackets or Chafer grubs beneath your turf.

These insidious pests munch their way through the root system of your beautiful lawn, killing your grass blade by blade. By the time you see visible signs of their activities much of the damage has already been done. And, until recently, there was little you could do to stop them

Leatherjackets

Have you seen ‘Daddy Long Legs’ around in late summer and autumn? Also known as Crane flies, these spindly-legged insects that flutter around so irritatingly have developed from the very larvae that have probably been tucking into the roots of your lawn causing the unsightly damage you’ve seen.

They are a problem on most soils. The grub can be found in greatest numbers in damp soils and heavier clays. Commonly known as ‘Leatherjackets’, they have an enormous appetite for those juicy roots of the lawn that you have been carefully nurturing for months or possibly years.

These root-chewing grubs can ruin your lawn. Even more damage may be caused by birds and wild animals when they probe and loosen the turf to feed on them.

LIFE CYCLE
Late summer/early autumn
Adult Crane flies emerge from the soil to mate. Each female then lays up to 300 eggs in the grass. Two weeks later the eggs hatch and the larvae (Leatherjackets) begin feeding on the roots and stems just below the surface of the soil.

Winter
The larvae may remain dormant in the soil throughout the coldest months but resume feeding as soon as the soil warms up in the spring.

Late spring/early summer
Damage becomes most noticeable as the larvae are now bigger and more voracious. They can grow up to 5cm (two inches) long.

June to August
The leatherjackets become fully mature by June, becoming inactive and pupating in August just under the surface of the lawn to emerge as adult Crane flies thus beginning the cycle again.

Chafer grubs

Chafer grubs are the larvae of a few types of Chafer beetle, also known as Cockchafers or Maybugs. You may have heard these beetles clatter against your window on a warm summer evening, attracted by the lights.

These larvae also munch their way through the roots of your lawn. Their distinctive creamy colour and curled-up shape makes them easily identifiable if you turn back a section of damaged turf to reveal them. Chafer grubs are commonly found in light sandy or chalky soils.

As with Leatherjackets, damage is caused not just by the grubs themselves but by birds and even large mammals such as foxes and badgers digging to feast on them, spoiling the surface of the lawn.

LIFE CYCLE
April to June
Adult beetles emerge from the soil. They feed on fruit, leaves and flowers and lay batches of eggs each night over a number of weeks. Eggs hatch in 4 to 6 weeks and the chafer grubs begin to feed on the roots of the grass immediately.

Winter
In the winter the larvae become fully developed and burrow deep into the soil to hibernate. As soon as the soil warms up they start feeding on your lawn again. With fully mature grubs as large as 40mm (about 1.5 inches) long these infestations can result in a great deal of damage, compounded by the harm to the lawn caused by the predators that feed upon them.

Late spring
Mature larvae become dormant briefly whilst metamorphosing into pupae, with the adult beetles emerging around April/May to start the life cycle once more.

• Q Is the product easy to use?
• A Yes, just use one sachet in a watering can to treat 10 square metres and water onto the lawn as directed on the pack.
• Q When should I use this treatment?
• A It should be applied during the egg laying period of the pest being targeted. For leatherjackets this is ideally mid August to September and for Chafer grubs in May and June. If both pests are present treat in late June or July for best results.
• Q How many times a year will I need to treat?
• A One treatment per season is recommended; Provado Lawn Grub Killer is a systemic product and will give control for up to one season. 
• Q How quickly does Provado Lawn Grub Killer work?
• A Provado Lawn Grub Killer begins to work as soon as it is applied. It has a systemic action which distributes the active ingredient (imidacloprid) throughout the lawn root system so that when any lawn grub ingests a piece of root it will stop feeding immediately and subsequently die. Equally imidacloprid will be absorbed directly from the soil by any grubs present at the time of treatment and its action is to change the behaviour of the grub which prevents it from feeding immediately, again leading to its death.
• Q The instructions tell me to use this product preventatively, can it be used curatively?
• A Provado Lawn Grub Killer works best when used during the egg laying period as the product is most effective at the early stages of development. Leaving treatment until the late stages means there could be significant damage of the lawn.
• Q What conditions do Leatherjackets and Chafer grubs like best?
• A Both grubs thrive in most British soil conditions. Chafer grubs favour sandy, chalky soils whereas Leatherjackets can be found in most soils but heaviest infestations are found in damp or clay soils. If you have seen Daddy Long Legs hopping along the lawn in autumn then this is a sign they will have been laying eggs in the lawn. If your lawn has previously suffered from yellow, brown or bare patches from spring onwards then this also indicates a potential problem.
• Q Can I allow my rabbit to feed on the lawn once I have applied this product?
• A As a precaution animals such as rabbits and guinea pigs should not be allowed to graze the treated area for 4 weeks and mowing clippings from the area should not be used as forage.
• Q What are the ideal conditions for best results?
• A As for other lawn treatments such as feed and weed products, try to avoid very dry or waterlogged soil conditions. Early evenings are usually best. 
• Q This treatment is for the larval stage of the pests, do the adults do any damage?
• A The adult chafer beetles do feed on the foliage of ornamental plants but the damage to these is rarely noticeable.
• Q What are my alternatives for treating these pests?
• A Cultural methods such as covering with black plastic and biological methods such as nematodes may provide some benefit, but it is important to use these under ideal conditions i.e. the correct temperatures and moisture levels and correctly identify the pest involved.
• Q What effects will Provado Lawn Grub Killer have on the environment and wildlife?
• A There is no need to exclude pets, children or wildlife when this product is used as directed. The active ingredient, imidacloprid, is widely used around the world and has many uses, even in veterinary medicine.
• Q The label says ‘high risk to bees’, what does this mean?
• A You should use the product only as directed on the label and therefore avoid harm to bees. Mow the lawn beforehand to remove flowering weeds. Apply in early evening when fewer bees are around. Wait until bulbs in the lawn have finished flowering before treating.
• Q Do I need to take any special steps after I have treated my lawn?
• A Once the product has been watered in there is no need to change your normal lawn maintenance programme i.e. regular mowing, feeding and weeding.
