Why There’s a Correlation Between Crusting and Flies

One of the challenges that come with manure management is the formation of crust on the surface, which can attract flies and create a breeding ground for them. Healthy Farms takes a closer look at how crusting and flies relate and discusses some strategies for preventing fly infestations through proper manure management.

How Do Crusting and Flies Relate?

There is a relationship between crusting manure and the presence of flies. Flies are attracted to decaying organic matter, such as animal manure, which becomes more appealing to them when left to dry and form a crust on the surface. The process of manure crusting can also create an environment that is conducive to the development of fly larvae, as it traps moisture and heat. As the larvae mature into adult flies, they can become a significant pest issue around livestock facilities.

The Causes of Crusting

The reasons for the formation of crusting are as follows:

  • Usage of water-conservation techniques that result in a low ratio of liquid to solids
  • Presence of floating grain hulls and fibers in the feed
  • Non-digestible fiber in manure caused by the use of DDGS feeds
  • Accumulation of hair and feed dust

Initially, a thin layer forms over the water surface, and gradually, more solids accumulate above it, resulting in the formation of a crust. This crust provides a favorable breeding ground for maggots. Additionally, fiber from distiller grains helps to hold the manure above the water level, contributing to the formation of a thick and hard-to-disturb layer of waste.

How To Control an Exploding Fly Population

The correct moisture content of fresh manure or any organic matter provides an ideal breeding ground for flies. It is easier and more cost-effective to prevent and manage a buildup of fly populations than to address them once established.

Here are some quick measures to address a surging fly population:

  • Agitate the manure pit with biological control methods to break up the crust and submerge it, which will drown the eggs and maggots.
  • Activate soakers and sprinklers inside the building to dampen the crust to an extent that is too moist for eggs and maggots to thrive.
  • Ensure proper ventilation.
  • Regularly remove manure.
