## 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 . Nemasys Leatherjacket Killer Is A Perishable Product, So Once You Receive It, It Will Keep Up To 2 Weeks In The Refrigerator And You Will Need To Use Before The Expiration Date. Please Do Not Until You Are Ready To Apply. Each Pack Treats 100M² In September October Or 50M² At Any Other Time Of The Year Can Be Applied Throughout The Year But Is Best Applied At Double Strength .
