Killgerm unveils new wildlife conscious rat bait box


The AF® Amicus is a new species-specific bait station for Norway rat control from BPCA member Killgerm Chemicals.

It precludes entry by bank voles and wood mice, while still allowing access for Norway rats (Rattus norvegicus).


When carrying out an Environmental Risk Assessment, the decision to use rodenticides must take into account the most efficient way to alleviate the problems caused by rodents, while presenting the least risk to non-target animals.

The AF® Amicus has been designed to prevent non-target species from accessing the rodenticides and traps inside. The new tamper-resistant and species-specific bait station has two ‘tube’ entrances that Norway rats can climb up.

Placement at the correct height is critical to allow this and to prohibit entry by wood mice and bank voles.

The unique downward facing tubes naturally attract rats and allow them to climb up into the box, giving access to the rodenticides or traps inside. In testing AF® Amicus was not entered by non-target species such as wood mice and bank voles. Slugs and snails also have not been observed to enter, therefore preventing rodenticide damage.

Iain Urquhart of BPCA member company Advanced Pest Management, who created the AF® Amicus commented, “I knew the design of conventional bait stations allowed for non-target animals to gain access to rodenticide baits. Something had to be done. So, it all started in June 2012 when the expression “rat up a drainpipe” kept on being repeated in my head. It gave me an idea.

"I doodled with a conventional bait station, bringing it up off the ground, and the idea struck me of placing a pipe up into the box. I drew up some plans and had my brother-in-law make up a box with two tubes suspended from the box.

"I experimented with the bait station, enlisting the help of a researcher and an independent testing facility, over a period of 4 months. We came up with a design that allowed for rats, of eight weeks of age and above (adults), to gain access to the box but at the same time precluded mice from entry.

"The fact that no snails managed to gain access to the bait stations, once tested in the field, I have to admit was just an added bonus.”

Accessible to technicians, and with a removable door that also acts as a useful shelf, AF® Amicus will hold many of the usual types of rodenticides and traps while being easily installed with just four screws.
