Our neighbor relocated about 40 squirrels. She maintained a neighborhood leaderboard of red, black, grey and brown squirrels. Once the city found out, they threatened to fine her big time. 

 Damn. That's a lot of squirrels. 

 Yeah, we had an infestation. It was really bad. 

 My grandfather used to shoot them with a .22 after a squirrel broke into his house, are peanuts that were in the counter, a shit all over their living room. 

 We had an infestation in the attic of our house. The strategy to get rid of them were dehydrating treats and a one-way exit outside.
