Last year I made some entrance reducers which I dubbed, “The Gauntlet.” The idea is that it’s easier to defend a long, narrow corridor rather than a shallow doorway. Enter The Gauntlet, an entrance reducer made of 1×2 lumber (dimensionally 3/4″ x 1 1/2″). Using your table saw, cut your entrance to allow no more than 3/8″ entrance height. Width of the entrance is of your choosing but if you need The Gauntlet you probably need a smaller than usual width. Make several, some as small as one bee width. The result is a 3/8″ high, narrow corridor, 1 1/2″ long hallway for any intruders to navigate before they get inside. No need to even pull your old entrance reducer either, just place in front of the old one.
