The scientific name for the no-see-um is Ceratopogonidae, but it has accumulated more common names, including sand flea, sand fly, biting midge and punky.

No See Ums (Biting midges) can be a nuisance to anyone who spends time outdoors during early morning and evenings.   Even during the daytime on still, cloudy days they will readily inflict irritating, painful, bites.  For some, their feeding can cause long-lasting painful lesions on exposed skin.

Bite prevention is the preferred way of dealing with these pests. Your home or business can be protected with a special screening which is available to exclude these fliesMost biting midges can pass through a 18 x 16 or 16 x 16 mesh insect screen, so a smaller opening  size (higher mesh count) is required to prevent entry.

These screens are top quality, precision woven Marine Grade T-316 Stainless Steel, not cheap Plastic, Polyester or other synthetic material that requires frequent replacement.  Stainless Steel no-see-um screening will last a lifetime in most applications when properly maintained. Due to the superior strength of stainless steel, smaller wire diameters allow superior open area (visibility) to synthetic materials.

The table below lists the most popular screens utilized to prevent entry of small flying insects such as aphids, gnats, no-see-ums or biting midges.  Select an opening slightly smaller than the pest you wish to exclude.

Be sure to consider the "Open Area" as standard insect screen has a typical open area of 66 to 71%. As the open area is reduced a proportionate reduction of visibility and air flow through the screen will result.
