Adhering strictly to the application timings will ensure that any remaining colour in the bowl will be due to the inert carrier only and that you have performed an even application. Continue to keep the lawn moist for up to 2 weeks after application. Repeat these instructions for an introduction of a second nematode sachet application 7 days after the first application. Repeat applications may be required for severe applications. Full instructions are provided on delivery. Can I Store Nematodes?

To aid the efficiency of the nematodes into the soil profile, apply with Aquazorb 45 Wetting Agent. Garlic Spray: A bitter-tasting spray on the grass will discourage the grubs from eating the grass an they will wriggle away. Hopefully to be caught by birds or swept up off your patio. I have a professional organic garlic spray which I can apply to customers lawns, or you could try to make some yourself by soaking crushed cloves in boiling water overnight. It is very important to irrigate immediately after application, water the grass well so the nematodes are washed below the thatch layer into the soil to reach the roots where the larvae will be feeding. Irrigate immediately after application using 2-5 mm water to help wash the nematodes into the soil. Dobies strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3.

In spring, when the ground temperatures rise, they will reappear and start consuming the grass roots and some top growth.

Due to the fact that biological controls contain living organisms they have a short expiry date and should be refrigerated prior to use. The best form of protection is prevention. EU legislation has restricted the use of pesticides but you can employ organic solutions which don’t require a pesticide certificate. These are called ‘nematodes’, which are microscopic worms. They enter the grubs and infect them with a bacterial disease which kills them. Nematodes are available from various horticultural suppliers, but be warned; timing, soil moisture and the age of the larvae are all critical if the treatment is to be successful. Soil temperatures should be above 10℃ for the nematodes to be active, if applying in the spring. How Do I Apply The Nematodes?

Natural Control and Killing of Leatherjackets in lawn areas

These application windows coincide with the larvae being at a young and susceptible life stage and the soil temperature being above 12ºC, which is the minimum point the nematodes are at their most active in the soil. Getting them out of the lawn and a target for birds and other predators is a good thing though. I have added this to my treatment recommendations. Method 5 – Encourage insect-eating birds.
