We've been seeing a lot of large wolf spiders in the house. One evening I was on the computer and thought I saw something out of the corner of my eye. Ugly thing came right up to where I had my hand on the mouse. I backed away so fast and ran to get the camera. If you have a wheel on your mouse, it covered the whole corner of the mouse wheel and left side click button. I also missed it with the flyswatter. But my glasses flew off my desk. Never saw it after that. DH stepped outside this morning to let the dogs do their business and a tarantula was trying to get into the door. it was about 4 inches from tip to tip. Eeeeekkkkkkk!
