Help! I just can't catch the little devil, as it leaves, each nite too late for me..around 2:00am. Is there any kind of a one-way trap door I can use? Anything suggestions that are non-toxic? I am trying vinager/hot sauce..are there always more then one? I have an opening that is 4"X5" put a screen over the opening so that it has to push thru this to get out..and my cats can't get in after them (it) I could get a live trap..but then I am stuck with the trap..if it sprays..don't want to put it in our car to take the trap back to animal shelter (I can rent it)....need new ideas! thanks!
