raccoons are throwing a pool party every night in my pool. 

I can't believe this how do I fix this? For weeks we would wake up and find poop in our pool. We always thought it was an iguana. Nope! I set up a camera last night and the answer is there are pool parties going on every night. the first group, a mom and 3 kids swimming around. 2nd group of adults of 6 swimming around. Then to top it off a 3rd group of 5 pooping in the pool. What do I do???
