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.

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.
