Here, we report cases of bats entangled in natural and artificial traps in Brazil. We found 10 bats entangled in barbed wire, including one Artibeus fimbriatus (dead), one each of Artibeus lituratus, Lasiurus blossevillii and Lasiurus cinereus (alive), one L. blossevilli and five Myotis levis (mummified) and one Eptesicus diminutus entangled on adhesive spines in a branch. All were adult bats. Although we cannot control the occurrence of natural traps, we can suggest actions to mitigate negative effects of man-made structures. The most economic and effective way to mitigate these negative effects is to use plain wire to construct fences.
