Bat Guano Clean Up

Guano Removal Overview

The smaller the animal the faster their metabolism and the faster the metabolism, the more feces they will produce. Bats have a fast metabolism, and this will cause them to excrete fecal matter between 20 and 30 times a day. When a person has an infestation of a colony of bats in their attic, they can produce a lot of bat guano. Along with having to remove the bats from the attic of the home, the feces that they leave behind is going to need to be cleaned up as well.

Guano Damages

The presence of bat droppings can create a lot of different problems that will compound the bat infestation into a larger problem than it already is. Their guano is going to attract other animals and vermin into the area, such as cockroaches. This can turn a problem with bats into an infestation of multiple nuisance animals. Their guano is also corrosive to the wood, insulation, and metal that is throughout the attic. Lastly, and most importantly, their guano needs to be removed because of the diseases and infections that it can carry that humans are able to contract.

There is a process that must be followed to make sure that everything is cleaned up and it should be conducted by trained professionals, like those at The Critter Team.

Guano Removal Process

1. First, the bats must be completely removed from the space and relocated by professionals. They need to be removed and all of their possible points of entry need to be plugged up or repaired so that bats will not be able to re-enter the space.

2. The loose guano needs to be vacuumed or swept up. While this cleaning process is taking place, full protective gear needs to be worn. This includes full-coverage protective suits, gloves, and respirator masks. Care needs to be taken to make sure to limit any inhalants that may be released into the air.

3. Any and all soiled insulation needs to be disposed of. This is a material that is not going to be able to be cleaned properly. Insulation that is soiled and not moved can serve as a material that can harbor the growth of fungus and bacteria that has been left behind by the bats in their guano.

4. Then the entire space needs to be cleaned with an enzyme-based cleaner. This type of cleaner can be used in a spray and fogger form, simultaneously. This will guarantee that all the surfaces of the space have been cleaned. This type of cleaner is going to break down the organic material that the guano will leave behind.


Once the attic space has been cleaned and scrubbed with the enzyme-based cleaner, the homeowner can focus on fixing any of the structural damage that may have been caused by the bats and their fecal matter. If the problem was caught and dealt with fast enough, this damage can be held to a minimum. This is a process that can be stressful, but it is not something that is impossible to fix and move on from.
