My tenant in a 2nd fl apartment claims to have a mouse issue. He's tried OTC things. Now he wants to get an adult cat to help out. What have you used for mice and had good success? --98.237.xx.xx

Mice exist - deal with it. Spiders too. --75.7.xx.xx

Good kitchen cleaning and snap traps. Snap traps are more humane than anything else, imo. Quick death, no suffering. If the kitchen isn't clean, a cat isn't going to clean it. --70.92.xxx.xxx

Has anyone tried mixing flour with plaster of Paris and cup a soup? Saw a YouTube video on it. I was planning on trying it out. --96.237.xx.xxx

He just wants a cat. Go over and look around. What do you see? Put poison done if needed. Steel wool at access points.. --73.230.xxx.xx

I second... he just wants a cat. No cat. My mice traps and peanut butter. --172.58.xxx.xxx

Some times an adult cat will just watch the mouse and not catch it. Ask for evidence of mouse such as a sprinkling of mouse poo on the kitchen cabinets, stove etc. If he's a good tenant and pays, then let him get his cat but make sure it's neutered. --108.24.xx.xx

The apartment isn't as clean as I think it should be. Also the downstairs tenant have no mice. I did give him some professional mice bait to use. I also told him nicely to clean good but I dont think he thinks thats an issue. --98.237.xx.xx

Another vote for 50 cent snap traps baited with peanut butter. Agree that he just wants a cat. --100.34.x.xx

Sticky traps with peanut butter in middle good too. I have to kill them though because stuck by glue is an awful death. --216.23.xxx.xx

When setting snap traps, I wear disposable latex gloves to avoid leaving human scent on the traps. I find that setting pairs of traps back-to-back along the perimeter works best. --71.174.xx.xxx

Yet another vote for good old fashioned snap traps with peanut butter. At 50 cents each, you throw the trap away with the dead mouse. Do not place poison bait indoors. Mice will die and cause a bad odor. I put baits in detached garages and sheds. --107.141.xx.xxx

And modify your lease to make the tenant responsible for pest control. If they took possession of a pest-free unit, they should be held responsible to keep it that way. --107.141.xx.xxx

Also, there is a poison, green pellets in clear bag, that makes the rodent very, very thirsty. They leave in search of water. The water activates the poison, they laid down go to sleep. We use this a lot at the Lake house, because they go down to the lake for water. --173.31.xxx.xxx

Go over yourself and set traps and put out poison. Don't believe the tenant when he tells you he has done it himself. --76.178.xxx.xxx

Can't speak to your state laws. In Pa, the LL is responsible for pest control in a MFH. Since this is a top floor apartment, you might want to listen to your resident. The neighbors might also have a mouse problem too. I would be surprised if they don't --24.101.xxx.xxx

Oppppps Your place just might be in Pa....if its a Multi, you are on the hook. Some of the best answers might come from the resident. If they are not happy with the results - whose idea was it? --24.101.xxx.xxx

I found the sticky traps to work the best for mice. I wasn't particularly concerned about whether that was humane or not. If they didn't want to die unpleasantly, they should have stayed out of my house. --209.122.xx.xxx

Just check your sticky traps often so that you find the mouse shortly after it has been caught. Transport the mouse and the sticky trap a few miles away, then generously pour some dish detergent on the the stuck mouse, then douse it with water from a bottle. The mice will slide right on off. You can then leave the mouse in its new neighborhood. --98.122.xxx.xx
