I seem to have an over-abundance of mason bees that will pack any hole/gap in everything from the grooves in stacked frame bars awaiting assembly to fuel line tubing, socket sets, propane torches and adjustment-screw holes (and other holes/gaps) in power equipment. This behavior is somewhat inconvenient and, at times frustrating.
Question: Will the provision of alternative nest sites (drilled wood blocks?) be likely to divert them from the undesired sites in favor of those provided?
Or will I simply be enabling the local population to increase even further, with the potential for creating an even bigger problem and finding even _more_ of my stuff packed with clay and larvae?
