Attic Cleanup and Bat Guano Removal

As an added service, Critter Catchers can provide bat guano  or entire attic space cleanup.  Our company maintains a residential builders license (License #2102196439) which allows us to remove both the bat guano and damaged insulation.

There are a number of reasons to have your attic cleaned.  Once the bats are evicted, there is generally evidence that they once occupied the attic.  This can become a problem, if you ever decide to sell your home.  It can be just enough evidence to scare away a buyer, or confuse a home inspector.  

Another reason to have the attic cleaned is when there is a significant buildup of fecal matter or you have some sort of insect issue from wildlife or other sources.  This buildup can contribute to staining on the ceilings and can compress insulation and compromise energy efficiency.  Some people are allergic to bat guano and experience typical respiratory or allergic symptoms. Additionally, bat can carry various ectoparasites such as ticks, mites and bat-bugs. Removing the soiled area may help reduce these problems.

We have a 13 HP gasoline powered industrial vacuum that is designed to remove contaminated cellulose insulation from attics.  The equipment is equipped with over 200 feet of 4 inch hose (pictured).  The vacuum is stationed outside and the hose is fed through your attic hatch, or soffit vent.

Additionally, we have the capability to replace insulation or to add a fresh layer of TAP Pest Control Insulation on top of your exisitng attic insulation.

Choose a company with a residential builders license, such as Critter Catchers for your attic cleanup needs. 

Histoplasmosis - Bat Guano

Health risks of contracting histoplasmosis has been highly publicized in the media.   This is the same fungal disease that is transmitted to humans through bird droppings (such as pigeons). 

Growth of the fungus requires a warm humid environment that is common under rotting logs or in rich organic soil. The fungus can grow in the buildup of droppings that is present under roosts that have been used for a long period of time (think caves).

Infection occurs after droppings are disturbed and spores are inhaled.  Most infections cause mild flu-like symptoms.  The disease can, on occasion, be fatal (just like the flu). 

The risk of histoplasmosis exposure due to guano buildup in an attic is likely to be very low.  This is because people do not generally occupy attics where exposure might occur.  Also, most homes are maintained to keep moisture and water outside.  Despite all the bats that occupy attics in the state, there has not been a documented case of bat-induced histoplasmosis in Michigan. 

If you have exposure or medical concerns, contact your medical practitioner for advice.
