The product requires refrigeration and timely use within two weeks to maintain effectiveness, with flexible dosing options for year-round lawn care. ## Description Leather Jackets Are The Larval Stage Of The Crane Fly Or Daddy Long Legs. Control Leather Jackets Naturally By Treating With Nemasys Leatherjacket Killer. September October Is The Best Time To Treat As This Is When Leatherjackets Are Most Susceptible To Nematodes, The Soil Is Warm Needs A Daytime Soil Temperature Of 12C And They Are Close To The Surface. It Is Possible To Treat At Other Times Of The Year, But It Is Necessary To Apply At Double Strength. Each Pack Treats 100 M2 Same Pack Treats 50 M2 When Applied With Double Resistance . Crane Flies Or Daddy Longlegs Lay Their Eggs In The Same Area Of Lawn From Which They Emerge, So Numbers Increase Quickly. These Eggs Hatch In Late Summer And The Larvae Immediately Begin Feeding On The Grass Roots. Leather Jackets Feed Though The Fall, Before Overwintering. They Emerge The Following Spring And Gorge On Grass Roots Before Pupating To Emerge As Adults In August The Whole Cycle Is Then Repeated. Birds, Particularly Starlings, Will Come Across The Lawn Looking For The Leatherjackets To Eat And Are A Certain Indication Of A Leatherback Infestation. Leatherjackets Are 1 Inch 2.5 Cm Long, Grayish Black, Legless, And Without A Distinct Head. Simply Mix Nematodes With Water And Apply With Watering Can, Hose End Feeder Or Nematode Applicator See B07Hf73Nrz .
