Elimination

We must first identify the source of development of these flies: decomposing organic matter. The larvae can only survive in this type of environment. Thus, carrying out the necessary repairs, removing all organic matter and drying up the premises is a sustainable solution to the problem.

If the presence of adult flies becomes inconvenient, it is possible to capture them with traps or keep them away by keeping the area clean and well ventilated.

Do not hesitate to request the intervention of one of our certified technicians. An expert’s eye can be very useful in eliminating sources of reproduction.

Actions

  • Find and remove decomposing organic matter (sewer backup).
  • Clean and brush drains, plumbing, and overflow outlets
  • Request assistance from one of our pest management experts

Prevention

  • Take care of drains to prevent surface buildup of organic matter
  • Repair and dry up after water leaks quickly

Description and development

Sphaerocerid flies or small dung flies are holometabolous insects (having four very different life stages) in the Sphaeroceridae family of the Diptera order. There are many species of these flies in North America. As their name indicates, they are small—usually less than 5 mm—and are generally dark brown in color. They can fly for short distances or move about in quick hops.
The eggs are laid on damp, rotting organic matter. After the eggs hatch, the insect develops through the larval, pupal, and adult stages. The life cycle (egg to adult) takes only a few weeks. The larvae feed on the organic matter on which the eggs were laid.

Habits

These flies proliferate in the presence of damp, rotting organic matter. Small dung flies usually develop inside homes following a break in a pipe or a sewer backup. They can be seen flying around the house or sitting on window sills.
