Few people actually enjoy picking up bugs or squashing them with their bare hands. Most of us employ the help of paper to lure them outdoors or at least create a barrier between our skin and their soon-to-be-crushed bodies. Neither of these options are efficient or simple. A lint roller, on the other hand, is.
Redditor silentwail discovered that ridding the house of scorpions was not only easier but safer by simply rolling over their bodies. The creatures stuck to the paper and could be easily brushed off afterwards. This method should work just as well for just about any other gross critter that infiltrates your home. So long as you don't mind a little insect cruelty, it's an efficient disposal method.
