There have been at least a dozen plague alerts in Los Angeles in the past twenty years. Officials response? "It's the squirrels, man."
Before anyone worried about terrorism or illegal aliens, we had squirrels.
And if you need rat glue traps, get the Victor ones at Orchard Supply....
Bought some lame ones at Home Depot and all the pests did was make it look like Grummans Chinese with all the footprints in the glue.
