If you have a black fly problem, follow this DIY guide for product suggestions and instructions on how to effectively get rid of these pests.
Identification
Because it might be difficult to tell the difference between different types of flies, it is important to correctly identify the type of pest you are facing. This will ensure that you are using the correct products and methods to get rid of this particular pest.
- The black fly may go by other names such as the buffalo gnat, turkey gnat, or white socks. It can be anywhere between 2 and 6 millimeters long in length, with short legs and large eyes.
- It has antennae and large wings. True to its name, most black flies are black, but some might be yellow or orange.
- While males get most of their food from nectar, the majority of flies feed off blood from livestock. The female black fly can lay up to 500 eggs at a time after feeding on blood, and these eggs will hatch anywhere from a few days to a month after. Only females will bite people, livestock, and other animals as they require blood in order to produce eggs whereas males will only feed on nectar.
- Eggs are always laid in running water; each egg has silk particles that keep them secure while they feed on bacteria and algae. Feeding time for black flies is in the daytime when wind speeds are low. Flies will never enter areas where humans live when looking for food.
- They are most active between the months of May and July.
- Typical bite sites for these pests are around the neck, behind the ears, and behind the lower legs. Bites are very painful, and may swell and itch.

Inspection
Once you have identified your pest as the black fly, take a close look at and around the area where you are experiencing problems to effectively treat these locations.

Black flies live and breed around areas with running water. This makes sites such as rivers and lake areas ideal for their egg laying activity. Rural properties close to running water may be more prone to black fly activity than suburban residential areas, but that more or less depends on local geography. If you have been experiencing black fly activity, take note of any sources of running water that are on or near your property.
Check areas where livestock are most active, such as barns or pens. The female black flies will feed off the animal’s blood while the males will be attracted to their waste. Areas with running water will most likely be an egg-laying area for black flies. If you are noticing black flies in your living quarters, it might be because they are infesting an area nearby.
What to Look For
If you have livestock, inspect your animals for bite marks or wounds around their ears and mouth. Fly bites can appear as red, swollen welts on animals. Black flies can appear in swarms and be bothersome to anything in their way.
Treatment
Now that you have inspected the area where black flies are infesting, you can begin treatment. The product you will be applying is Flex 10-10 Insecticide. You can apply Flex 10-10 with a hand pump sprayer, hose-end sprayer, backpack sprayer, spray rig, automatic misting system, or ULV spraying system. For general applications, a hand pump sprayer is recommended.
Flex 10-10 is a broad spectrum product for indoor or outdoor control. You will want to treat any areas the flies are in or around, as well as your livestock. Be sure to wear the proper personal protective equipment (PPE) before handling or applying any product.
Step 1 – Measure the Area
Before applying any product, you will want to measure the square footage of the area you want to treat. You can do this by multiplying the length and width of your area together (length x width = square footage). The mixing rate for outdoor applications of Flex 10-10 is 6.4 fluid ounces per gallon of water. One gallon of solution will typically treat 1,000 square feet. For example, if you wanted to treat a 2,000 square foot area, you would need to mix 12.8 ounces of Flex 10-10 in 2 gallons of water.
If you are applying Flex 10-10 to your animals, the mixing rate would depend on the severity of the fly infestation. For normal conditions, mix 4 teaspoons of Flex 10-10 per gallon of water. For severe conditions, mix 8 teaspoons of Flex 10-10 per gallon of water.
Step 2 – Mix Flex 10-10
Now that you know how much product you will need for your treatment area, you can begin making your solution. Fill your spray tank halfway with water, add your desired amount of Flex 10-10, then add the remaining half of water. Close the tank and shake well to agitate.
Step 3 – Apply the Solution
When you have finished diluting Flex 10-10 in water, you can begin applying the solution. Use a direct spray to treat areas where black flies can land to rest such as walls, ceilings, screens, door frames, window frames, and other similar places.
Be sure to remove all livestock and people from the area and cover all food before applying your solution. Be sure not to apply Flex 10-10 near water. If you are applying this on your animals, use a fan spray setting.
Make sure you use enough product to wet the hair thoroughly, especially topline, underlines, flanks, withers, and other infested areas. You can reapply treatment to your livestock every 5 to 12 days until there is no more fly activity.
For a more active approach to treatment, Flex 10-10 is labeled to treat black flies in the air with the use of a space spray application or an automatic misting system. With the proper equipment, you can space spray Flex 10-10 with an application rate of 3.2 fluid ounces of product per 1 gallon of spray dilution. Do not apply with humans or animals in the vicinity, and keep the area closed off for at least 10 minutes.
With an automatic misting system set up in livestock or animal housing areas, create and apply a solution of 0.09% permethrin and 0.09% PBO. This is done by mixing ½ a gallon of product with 55 gallons of water. The delivery rate should not exceed 1.25 fluid ounces of solution per minute, and the automatic misting system must not be designed to release pesticides where feed or water is directly exposed to spray mist.
Prevention
After treatment, there are a few steps you can take to make sure that black flies are unlikely to return to your area. In large, you need to focus on sanitation. Most black flies are attracted to blood, but they also feed off of waste. We suggest the following measures to take to discourage black flies from targeting your property:
- Clean your area thoroughly and dispose of any garbage. Consider using trash cans with lids to keep trash concealed.
- Reduce moisture in your yard by keeping your drains clean and remove any stagnant water from your home.
- Be sure to keep your home and yard clear of pet droppings, and consider installing screens in your doors and windows to keep bugs outside.
- Retreat quarterly with Flex 10-10 as the residual protection is necessary to repel black flies from the treated areas.
