February in Fort Worth and Arlington often brings the first crane flies drifting over the lawn. Locals sometimes call them skeeter eaters, yet the adults do not bite. The real issue is underground. Small larvae called leatherjackets feed on roots and crowns of Bermuda and Saint Augustine grass. Damage can look like thin turf or weak patches that do not respond to extra water. If that pattern sounds familiar, it is worth learning what is happening below the surface before you assume the sprinklers are wrong.
How crane fly larvae hurt warm season grass
Leatherjackets live in the top few inches of soil, often where thatch stays damp. They chew roots, so grass may pull up easily or look pale in irregular patches. The problem is easy to confuse with compaction, drought stress, or grub damage. A quick check in a thin area can show whether larvae are present. If you are unsure, a lawn professional can help you tell crane fly activity from other lawn insects.
Moisture, thatch, and where problems start
Crane flies favor lawns that stay wet on the surface. Heavy clay, poor drainage, and thick thatch all hold moisture longer. Core aeration can help water move through the profile and reduce the soggy pockets where larvae thrive. Our guide on thatch in North Texas lawns explains when that layer needs attention.

How SureGuard approaches lawn insect control
We scout the lawn, note grass type and moisture patterns, and match treatment timing to what is active in the soil. Products are selected to reach larvae in the root zone without treating the whole property on guesswork. Grub control and general lawn insect control may both be part of the conversation depending on what we find. Follow up visits help confirm whether the turf is filling back in and whether aeration or fertilization should be part of recovery.
Recovery also depends on feeding and watering habits after treatment. Lawn fertilization on a sensible schedule gives grass the energy to regrow roots. Core aeration on compacted or waterlogged areas supports the long term health of the lawn, not just a single pest event.
