The Rodent Baiter are not tamper resistant so if there is bait placed inside of it, a rodent can disturb the bait station and the bait could come out. We would recommend securing the bait stations the best way that you can.
The Rodent Baiter has not be known to explode in hot conditions. They are safe if used as directed.
The Mini T-Rex will not fit in the Rodent Baiter for Mice. It will fit in the Protecta Mouse Bait Station.
Unfortunately, rats would not be able to access the Rodent Baiter for Mice stations. The opening would only be large enough for mice, Should you need a station for rats (which will accomodate both mice and rats) we recommend the Rodent Baiter 2525 for Rats.
