No-see-um netting?

**Woodsie8** · 04-22-2016, 10:43

I see a lot of nets with numbers, like 154 guage netting. What is the number on no-see-um? Also, do we need that kind of netting in Oregon? What does it keep out?

Pretty sure it keeps out No-See-Ums...

(and anything larger!)

And I'm pretty sure you have N-S-Us in OR.

Can't answer the question on gauge size.

I have always wondered if it was just a generic name also.

I don't think No-See-Ums is an official genus/species/blah blah... So knowing if that means just something I can't see or something that's a specific number of microns in diameter is a valid question.

No see um is a common name for them...a very tiny biting insect that as the name suggests, are very hard to see because they're so small. Smaller than a flea. I don't encounter them often here in NY, but I know in some places they are a yearly scourge similar to the way gnats are here at certain times of the year

I don't run into them very often in Oregon, but when I have, they have been voracious (Near rivers on the West slope of the Cascades)! I would definitely want no-see-um sized netting in Oregon. Sorry, I don't know the number.

No-See-Um is a common/non-scientific name for various species of sand flies. Probably more common along the coasts and near salt water but existing all across the non-arid parts of the country.

As stated, smaller than a flea (by quite a bit.)

They are awful in Scotland. Just awful

Key for protection against no-see-um's here in north PA is to use the netting with a triangle shaped hole. Much of the no-see-um netting I have seen for sale differs only by weight per square yard but with the same sized triangle shaped hole. There have been no-see-um nettings sold with number of holes per inch specified. Often these holes are shaped more like a circle and not a triangle. The circle style of nettings has not worked for me at all as the no-see-ums still get through and eat me alive.
