On occasion, one or two bats may get into a home and fly around. Often it may be a big brown bat that entered accidentally through an open window, door or ungrated fireplace. When this happens, there is no need to panic, for it will not attack even if it is chased.
The bat usually will find its way back outdoors by following fresh air movements. Leave windows or doors open to help it escape. Also, turn off all lights; if any are left on, the bat may seek refuge behind wall hangings or drapes. If a bat refuses to leave, it can be caught with a net, coffee can or gloved hand and released outside. If it remains into the daytime, look for it behind curtains, bookshelves, or someplace high. Grasp it with a gloved hand or put it in a container and release it outside.
