I was watching TV in the dark last night, and heard something flying into the window screen behind me.
Ten seconds later, a bat flies overhead. Swearing and panic ensued.
I went into another room and waited for it to stop flying around. When I came back, I couldn't find it. It appeared once more when I was looking behind a curtain. Myself, being the big baby I am when it comes to flying animals, retreated to an upstairs bedroom while the bat darted around downstairs during the night.
This morning, I went downstairs and could NOT find the bat. I cleaned the entire downstairs, checked behind and under furniture, curtains, appliances, etc. and found nothing.
Yesterday, I was cooking a pot roast and had the oven fan on for four hours. I noticed a pretty big gap where my gas insert fireplce's fuel line runs into the family room. My guess is that the fume hood created an air current through the chimney, and the bat followed it and got in.
Do bats leave on their own? I didn't have any windows open yesterday, last night or today. I looked everywhere and couldn't find the stupid thing. Just to be sure though, I have a pest control company coming next week because I can hear some kind of rodent or animal rustling around in the attic and in the walls.
Gotta love 130+ year old houses.
