Need a recommendation for an exterminator. I have what I believe is a rat, possibly more than one that thinks my back patio is a party house. It or they visit after midnight, leave their evidence for me to find in the morning. I haven't been able to catch them on the surveillance cameras. Bought rat poison housed in a plastic box but it took the bait out and feasted on it about 4 feet from the box. I'm so disgusted and don't know why it's visiting my house. There is absolutely no food outside except for bugs. I don't want to harm any other animals, I just want to kill this dirty rat!
