My male bumble bee will olny hook up with ONE of my normal girls. This is his second year breeding and he would only hook up with that same female. I have tried smearing plugs from another male on diffrent females, put him in with other females, put females in with him, put a fresh shed from another male, but he will only breed with that one female. Other females will breed with the other males so I know they are willing to breed. What should I try next?????![]()
