A few years ago I got into Mason Bees,I tried using the straws, but here in KY. it was so windy the straws would blow out causing me to lose my bee population. I had to go to an all wood house for them.And that has worked great. Barter is for 200+ straws. each pack has about 50 in them. So I am just gonna call it 200+ + as there are 10 that are not usable maybe? But way more than 200. Anyway, let me know what you have and see if we can barter. Thanks!
