All of the above are good advice about cleaning up after the infestation. When we had our issue our TT did not have a covered underbelly. We waited until dark, then I got under the TT. My husband was inside with a flashlight and we marked every spot that had even a pinpoint of light. We opened up enclosed panels (hot water heater & etc also.) The next day we plugged every hole with steel wool and Great Stuff. We then put the pellets that cause mice to need water in all of the closed spaces. We used that TT four more years and never saw any evidence of mice. Our present TT has a covered underbelly and we have not had any problems.....so far. lizzie
