Bat exclusions, glue traps, ceiling fans on at night and poisons are some of the dangers that bring microbats into care.
In Victoria, Australia, glue traps can only be sold to and used by commercial pest control operators with an approval from the Minister for Agriculture. They are not available for the general public to buy and use. Heavy penalties apply for illegal sale and use. Don’t we wish this was the case everywhere? The impact on microbats would be very similar to that as discussed below on rodents:
A scientific review of rodent control methods concluded that glue traps are one of the most inhumane methods of rodent control “because of the enormous distress these traps cause, even if the trapped animals are found after just a few hours and then humanely dispatched … rodents are likely to experience pain and distress through being trapped, the physical effects of the adhesive on functioning (e.g. suffocation), and trauma resulting from panic and attempts to escape, such as forceful hair removal, torn skin and broken limbs. After three-five hours, animals have been reported as covered in their own faeces and urine. When boards are collected, animals are also often squealing; one pest control operative even described them as “screaming their heads off”. Some rodents also bit through their own limbs to escape.
