I am in the process of doing a trap-out on a 2 year established in the side of house here at Spring, Tx. I used newspaper to block off all of the entrances except one, which i hooked a 1 1/4 PVC tube to and then connected the tube to the bottom of the TBH hive. I connected the tube up by itself for one day, then the next day hooked the end of the tube to the TBH. The first day the tube by itself worked well, with lots of traffic in and out of the hive. But, then when i hooked it up to the TBH on the bottom board, the bee's stopped using the tube. I have smeared Lemongrass oil in the TBH, the tube is level from the house to the TBH with a 90 deg elbow going up into the TBH from the transfer tube. I pulled the house faceplate loose and there are lots of bee's at the connection of the tube to the house. Is this normal to see little traffic going into the TBH on the first few days? Any and all comments welcome!
