The Aegis Rat Stations are not meant to hold rats (dead or otherwise) at all. These are bait stations which are meant to hold rodent bait blocks such as Fastrac Blox. The rats will enter the stations, feed on the bait, and then leave.
Aegis Rat Stations do not come with snap traps. These stations are not really designed to be used with a snap trap inside; however, we do offer the new EZ Snap Rodent Bait Station, which is a station with a rat snap trap built-in and a unique indicator zip tie for setting and monitoring the traps. This stations is also available with an attached concrete block.
One universal Aegis key is included with each case of Aegis Rat Bait Stations.
