How do You Get Rid of Bats?

For the past month or so we have had a bat or maybe bats under our carport at night.  They make a mess - right by our front door.

On the internet the only suggestion I could find was to use dog and cat repellent, so tonight I made a visit to Canadian Tire and bought some dog and cat repellent.  If it works it will be well worth the $12 I spent on it.

Bob hosed down the corner and sprayed it.

Below is a picture of Bob in his bat chasing outfit.
