Well adopted bait station

Right away: Rats seem to love this station, anyway the bait food is quickly gone. But I have to keep sparrows, a large board placed over it which, far more than is front and rear, where the openings of the station.

Negatives: I have the package and had not canceled it come even how to open the bait station, if it is only once snapped. I do not know if that was described on the package.
