Can bat guano be used as a fertilizer?
 

Guano is actually an amazing fertilizer, as it is high in potassium nitrate, which plants love. Consider placing the BatBnB above a low-traffic, non-edible garden bed and the guano will help the plants grow big and strong. Be mindful however, that if too much guano is accumulated it could burn the plant like too much of any fertilizer, too much nitrogen.  Interestingly enough, the potassium nitrate can also be extracted and used in gunpowder and explosives; guano was an important resource for that purpose during the American Civil War. Bat guano has also been found to preserve fossils.

Is guano dangerous?
 

Avoid touching or breathing in any guano personally, just as you would normally avoid any wild animal droppings. You’re actually more likely to get histoplasmosis from bird droppings than bat droppings, but nonetheless, steer clear of bat droppings and be safe. If you’re ever inclined to move your BatBnB or clean it up close during the winter after it’s already been occupied, then be sure to wear proper respiratory masks and goggles, and don’t breath in any dust. In general though, if you’ve never been overly concerned about bird poop in your life, then guano shouldn’t bother you.
