Rats Not Mice

[Bill Lee/Virginia]

I live near the largest ship yard in the world. I have a problem with rats (big rats) not mice. My wife feeds the wild birds and the seeds have enticed the rats to feed. The rats live under my storage shed and not in my attached house garage. Poison is not feasible. Rifles and BB guns are not allowed in this city (they will get you fined big time, ask me how I know). I have tried the water bucket thing and the birds eat the bait. I have purchased a small animal trap and used different baits but the rats do not go near it.

Help! What do you suggest?
