What Attracts Black Flies?

They are attracted to hosts by smell, heat, and sight.
They never go away but will expand their territory if conditions are right.
Are Black Flies Harmful?
How Long Do Black Fly Bites Last?
An anti-coagulant is injected, which causes the blood to run.
These bites can be painful and itchy and last days to weeks.
Some municipalities treat rivers and streams to suppress larval development.
But your best defense is taking a few steps to limit your personal exposure.
Use These Repellants On Exposed Skin
Use repellants on exposed skin if you must be outdoors.
Oil of lemon eucalyptus, picaridin and higher concentrations of DEET seem to be most effective, says Gray.
Natural repellants, such as essential oils, are not effective, nor areultrasonic devices.
Clothing that has been treated with permethrin also provides some protection, says Gray.
Bringing out a pest control company to spray your yard offers no more than temporary relief.
