  • The black fly, also known as the buffalo gnat, turkey gnat, or white socks, can be quite a nuisance. Our expert pest control team is equipped to handle any critter measuring between 2 and 6 millimetres in length.
    These pests come with short legs and captivating large eyes. Rest assured, we’ve got you covered!
  • The pest control expert has observed the presence of antennae and large wings.
    True to their name, black flies are predominantly black in colour, although it is worth noting that a small percentage may exhibit variations in colouration, such as yellow or orange hues.
  • While males acquire the majority of their sustenance from nectar, it is worth noting that a significant portion of flies derive their sustenance by consuming blood from livestock.
    Our esteemed female black fly, known for her remarkable reproductive capabilities, possesses the ability to deposit a staggering quantity of up to 500 eggs following a satisfying blood meal.
    These eggs, patiently awaiting their moment, will undergo the miraculous transformation into new life within a span ranging from a mere few days to a modest month.
    Females are the ones who will nibble on humans, livestock, and other creatures, as they need blood to lay eggs. Males, on the other hand, stick to sipping nectar.
  • Eggs are laid exclusively in flowing water, ensuring their safety as they consume bacteria and algae with the aid of silk particles.
    Black flies are most active during the daytime when wind speeds are low, as that is when they prefer to feed.
    Rest assured, areas inhabited by humans will remain free from the intrusion of flies in their quest for sustenance.
  • Pests tend to exhibit increased activity during the months of May and July.
  • Common areas targeted by these bothersome pests include the neck region, the area situated behind the ears, and the lower legs’ posterior region.
    Bites can cause significant discomfort, often resulting in swelling and itching.

Step 2: How To Inspect For Black Flies

Black flies, those pesky little critters, just love to make their homes and multiply in the vicinity of flowing water.

Our specialised expertise in pest control allows us to effectively address the egg-laying activity of pests in sites such as rivers and lake areas.

Rural properties in proximity to flowing water may experience heightened black fly activity compared to suburban residential areas, contingent upon the specific geographical conditions.

Please keep track of any running water sources that may be on or close to your property if you have experienced a black fly infestation.

Inspect high-traffic zones frequented by livestock, such as barns or pens. Female black flies, known for their blood-sucking tendencies, will indulge in a feast on the animal’s precious life force, while their male counterparts will be irresistibly drawn to the animal’s excretions.

Black flies tend to favour areas with running water as prime egg-laying spots. If you are currently experiencing the presence of black flies within your living quarters, it is possible that they have taken up residence in a nearby vicinity.

To ensure the well-being of your livestock, it is highly recommended to conduct a thorough examination of your animals for any signs of bite marks or wounds in the vicinity of their ears and mouths.

Fly bites are known to cause red, swollen welts on animals. Black flies, those pesky creatures, have a tendency to gather in large numbers and cause quite a nuisance for anything unfortunate enough to cross their path.
