AHBs will take over an European hive and they are very efficient honey producers. Their disadvantages are among others are their responses to perceived threats that Europeans completely ignore, the exaggerated aggression to the threat and the extended time and distance the response continues. Probably one of their worst habits is their intolerance to hive management and manipulation which they respond to by readily absconding for seemingly no reason. Cant make much honey if the workers run away all the timYes, they will colonize inside any space they think is safe. Honey bees will colonize inside buildings, under buildings, basically anywhere they feel safe and protected from the elements and threats. Feral bees routinely colonize inside hollow trees in the wild. Many times if you seal up the main opening and aren't thorough there will be gaps or alternative ways they can get in and out. Texas is warm enough to have Africanized Honey Bees (AHBs). Unless you're very skilled, it's hard to tell them apart by appearance. AHBs will attempt to "take over" a European honey bee colony if they find one. AHB's can be worked just like any other honey bee colony, you just have to use more smoke and better PPE. You also have to understand and warn others to stay away and to keep their animals away while you're working them. I kept bees in Colorado and recently moved down here to TX. I haven't set up my hives yet but have every intention of doing so. I understand the AHBs are actually better honey producers than the European bees.
