Q. "When do I need to apply nematodes , is it just if I see daddy long legs? Or can it wait until spring, Thanks" from Lee via the website.
A. Thanks for the message and it is always best to treat Leatherjackets in the autumn i.e. now as this is when the leatherjackets are newly hatched and the most susceptible to the nematodes. You can treat in April, but the leatherjackets are much more mature and much harder to kill so you need to apply the treatment at double strength. Therefore aim to treat in the autumn each year as you will get better results and the treatment goes further i.e. it treats 100 sqm when applied now but only 50 sqm in the spring (applied at double strength).
