What Do Bat Droppings Look Like?

Bat droppings, often referred to as guano, are a sure sign that these flying mammals are present. In fact, the pests’ small, brown feces will accumulate in piles directly underneath where they roost. Bat poop is frequently compared to mouse poop because the two are very similar in shape, size, and color. The difference between bat and mouse droppings is that guano is filled with insect and arachnid fragments, making the fecal matter shine when light hits it. Additionally, bat droppings are hard, yet easily crumble into dust. The stench of their excrement is particularly unbearable, even when compared to the droppings of other animals.

Problems with Bat Guano

Aside from the off-putting appearance of guano, bat droppings in the attic can cause many problems for homeowners. The build-up of feces over long periods of time can lead to structural damage in residences. In addition to a foul smell, bat droppings are also the catalyst for histoplasmosis. Caused by a fungus that grows in soil, this disease spreads when guano is disturbed, releasing dangerous spores into the air. Though symptoms vary, most individuals affected by histoplasmosis experience chest and lung issues.

Prevention and Removal

The best way to avoid bat droppings is to ensure that bats do not roost inside homes. In order to eliminate entry into attics, residents should securely seal and screen all cracks around the house, including roofs and eaves. When feces have been discovered, homeowners should not handle or clean it up, as the bacteria within can be released and cause greater threats. Since so many risks are involved with bat droppings and infestations, it is best to contact the wildlife specialists at Trutech to effectively and humanely remove the pests.

Do you do decontamination for bats after removal?

-Lakeland, FL


Yes, we always provide a sanitization treatment once bats are removed. Bat droppings (guano) are known to carry pathogens which can cause serious respiratory disease. Over time, the droppings get brittle and dry up to a dust which gets airborne due to movement or air flow (HVAC unit cycling air in attic, air flow through gable vents, human activity such as moving luggage, etc.). The droppings may become a major problem for those living in the home and must be addressed promptly.

Once the droppings are removed, Trutech will apply the sanitization treatment which decontaminates the affected area and makes it fine to use again. This process usually takes 1-2 hours but varies based on the amount of work needed to be done.
