Bat Guano Cleanup: Tips from the Pros

Bats, Blog Off 356

Bat guano inspectionIf you’ve ever suffered through a bat infestation, you know that one of the tell-tale signs of a bat infestation in your home is the strong smell of ammonia. The smell is a byproduct of bat feces, or bat guano, and the larger the infestation, the longer they are present in your home, the more powerful the smell.

A bat guano attic cleanup is nearly impossible for a typical homeowner to handle themselves. There are specialized tools and techniques that help professionals return a home to normal. Many of these tools and techniques are not readily available to a homeowner – hence the need for professional assistance.

Bat Guano Cleanup: Tips From The Pros

Below are the steps we take when assessing and cleaning up after a bat infestation.

  1. Ensure we are dealing with a bat infestation. Relying on sounds alone are never enough. A professional inspection and interview with the homeowner in an important first step to confirming the presence of bats.
  2. Follow our humane bat removal process. It is important to ensure the home is free of bats prior to starting a guano cleanup process. Because bats are a federally protected species, following this process if critical. We also ensure all bats are excluded from the home prior to beginning any bat guano cleanup. This process includes finding ALL access points and additional weakness that are yet to be exploited by bats or other animals and reinforcing.
  3. Understand the scope of the problem. Unlike most other animals that develop a latrine mindset and focus their waste in specific areas, bats are likely to expel waste throughout an attic. Because of the dispersion of bat guano, and because of the pre-treatment process (see next item) in most cases, we have to replace all of the insulation present in the attic.
  4. Pre-treat the insulation. Bat guano often contains a fungus that cause histoplasmosis. These fungal spores are very fine and can wreak havoc throughout the home if they go airborne. We first spray the insulation with a very fine mist spray to ensure the fine particulates that are harmful in the bat guano to not become airborne and travel throughout the home.
  5. Remove the insulation and other materials, if necessary. Once the insulation has been treated to prevent harmful particulates from going airborne, the insulation is carefully removed from the attic using specialized machinery designed to safely remove the hazardous material. At this stage, we assess and replace any damaged substrate materials.
  6. Break down organic material. Prior to installing new insulation, we treat the area with a material that breaks down all organic matter.
  7. Replace all materials to make as new. Lastly, we install new insulation, returning your attic (and the rest of the home) to a safe and warm state.

As you can see, this process is hardly something fit for a typical homeowner. Even the most capable DIY oriented homeowner should seek assistance with this type of project, as a misstep can be costly and dangerous, putting you, your family or visitors to your home at risk.

What They Say About ABC Humane Wildlife

I arranged for them to install wire screening on 2 sides of a concrete stoop to prevent animals from digging under my porch. (I have used this company in the past to remove animals from other parts of my property. They suggested this proactive work.) They called to remind me several days before their appointment. They came as promised. They did a great job of preserving landscaping gravel on the side before they dug. After digging down approximately 18 inches, they installed wire mesh screening down the 2 sides of the stoop. They then covered the area with the dirt and final layer of landscaping stones. You couldn’t even tell the area had been excavated when they were done!

We had bees crawling under exterior siding through a gap between siding and brick wall and wanted them eliminated. Phil the technician from ABC arrived at the scheduled time. He observed the bees and identified them as yellow jackets. Phil said he could eradicate them with a powder treatment and the bee activity would die down in a couple of days and we would be finished with the problem. Phil said if we still noticed bee activity after 7 days to call ABC and they would come back to re-treat the nest at no charge. It is just 3 days since Phil treated the nest and we have observed zero bee activity. We are very happy with the service and the remedy to our problem.

One by one, they removed a family of nine flying squirrels from our attic. The attic was completely cleaned and sanitized, and new insulation as blown in. All went well. It was easy to make appointments with ABC Humane Wildlife Control, and they were all very profession and prompt with their service. We dealt with many on their staff while trying to catch all the squirrels, and each of the representatives were friendly and helpful. We had some issues with the condition of some of the traps, but that was eventually resolved. They are a very helpful organization and the staff is very knowledgeable.
