I had never heard of buffalo gnats, but a quick google search turns up the info that these beasties are known as Black Flies up here in New England. I had not known they could kill birds!  They are annoying as snot to humans, I can attest. I will be watching now! Thank you for the article - and tips!
							
	

 Thanks for taking the time to bring this to peoples attention. Keeping the permethrin on hand is excellent advice, not just for gnats, but for other bird invading beasts as well.
