Doak, right I forgot to elaborate a little bit. I only used this type of entrance reducer for about a week. I was just really worried about the nuc being too small to defend properly, mostly nurse bees in there. I now have in place the one inch wooden reducer, like is so popular. I don't get robbing until late in summer around here, and then that is so minimal I don't even have to worry about it. The nectar flow goes on at my place all summer long, right until frost kill because of all the perennials and annuals that produce, self-seed and keep on producing until death of the plants. Have a wonderful day, beautiful life, today the sun is shinin'. Yeah!!!! Cindi
