What’s up with the chocolate sprinkles?

     I did not have to do a taste test to know this was not chocolate sprinkles.  It was bat guano.

Chocolate sprinkles?

     If you look VERY closely at bat guano, you can see the little sparkling pieces of insect wings and body parts.  The bats in this case, inhabited the house in the space between the wood framing and where the chimney went through the roof overhang.

     Now it so happened that there were indications of leaking into the roof structure from poor flashing details around the chimney above the roof.  Because of this, I was looking for signs of water and or damage to the interior ceiling areas.

     On the interior of the house there was some very light staining, with elevated moisture as indicated by moisture meter, around the corner of the chimney where it went through the ceiling----consistent with the poor flashing details I had noted around the chimney at the exterior.

Common place to find water damage and stains

     Once in the attic, and after I had crawled all the way to the far end of the attic, here is what I found.

Looks like bats have lived in this house longer than people

     A nice pile of wet bat guano-----acting like a sponge to carry the leak to the ceiling surface.  Sometimes this job drives inspectors batty.

You didn't take a deep breath did you?

I had an attic once with between 1 and 2 million bats and the attic floor had about 6" of guano all over it.  No kidding...

That's sooooooo disgusting.....how do people live like that??? they must have heard the creatures flying!!!!

Nasty. I hope you had your mask on if you were that close to the bat doody.

Posted by James Quarello - Connecticut Home Inspector (JRV Home Inspection Services, LLC) over 1 year ago

YUCK! I agree with Barbara. It is disgusting? Is this common in SEattle? I am thinking maybe I need to inspect my own home.

I hear you can use it in your garden quite successfully.  They charge a lot for it in the open market.

What a wonderful thought to start my day off...."If you look VERY closely at bat guano, you can see the little sparkling pieces of insect wings and body parts".

Posted by Amy Hahn, REALTOR®, Crystal Coast, NC (Pine Knoll Shores Realty) over 1 year ago

Most people don't know what to look for - great job in back tracking the problem.

Wow, Charlie B, you are up and at 'em early today...

Charlie: I am renting an apartment for the summer, since I rent my own home out for the same time period...last night I heard sounds from under the porch roof under my window...it was screaming or screeching and rustling around a lot! It scared me to death because I thought there was an animal trapped in there and my mind went nuts! What is it?...What if it is a big animal and it dies in there? How do I let it out? and on and on...I could not sleep all night! What do you suggest I do besides call the owner?

Thanks for sharing some of the reasons to keep bats out of your house. And, another good reason to have a professional home inspection for every purchase.

 Blooming for home buyers.

Bats just totally wig me out. I found one in my deck umbrella the other morning. My assistant and I looked pretty funny getting him out of there.

I think I will go talk to my neighbor today after reading this!  At our BBQ last week, she mentioned that they had a bat in their bedroom.  She hid under the covers while her husband caught it.  I asked them if they had checked their attic and they insisted the bats weren't in there.  I told them that it just seemed to me that a bat getting into the house had most likely come from somewhere else in the house.   Now I may know where they are hiding.

I went to a meeting about bat and bees a while back and was tempted to build a bat house in the yard, but my wife nixed the idea. The votes that count are in. Classify me as batty.

Mr Charles,

Cousin Nutsy, who is in Alaska, and I have had to cohabitate with bats. They are really quite creepy and not friendly. I am so pleased my career has led me to only the finest lodging at this point in my life.

HI Charles,

We do have quite a few of them here, but had not seen what the guano looked like. Thanks for sharing the pic.

Posted by Bill Saunders (Hot Springs Arkansas homes for sale (Diamondhead Realty)) over 1 year ago

Charles,

 

No Mosquitoes there ; ) You are now the "Batman". Bats in general are very good to have around but just not in your home.

Great Shots-

Charles - At least the owner will have help controlling the insect population--with the added benefit of free fertilizer.

Posted by John Mulkey, Housing Guru (TheHousingGuru.com) over 1 year ago

There's nothing like the fresh scent of bat guano to make your day!

Thankfully none of the homes I've sold have ever had this issue.

Posted by Craig Rutman Raleigh/ Cary/ Apex area Realtor (Helping people in transition) over 1 year ago

Bats are great at controlling the insect population.  Great right up to the point where they live inside your house.

Noted Paula's comment above - does anyone want to take a guess that it was raccoons mating?

Posted by Mark Hitz (Keller Williams ) over 1 year ago

I am so glad I will be able to recognize this the next time it hits me in the face.

Posted by Jane Peters - Los Angeles Real Estate DRE# 01439865 (Power Brokers Int'l) over 1 year ago

Yuck! I hope I never have to deal with Bat Guano. Thanks for the good pictures and helpful advise. I hope you can get the seller to fix it.

Oh gross and double gross!!  The pictures are great and make the point.  I remember as a 9 year old (many years ago!!) telling my parents there were sounds in the walls I would hear in the bedroom I shared with my little sister.  It took a while until they took me seriously and than the big event came.

My step-father lit a "something" up the chimmney and the sky starting raining bats!!  Like something out of a Hitchcock movie.  I, the rest of the family and neighbors were very impressed.

As if we needed something else to drive us batty.

Posted by Jack Gilleland (Home Inspection and Investor Services, Clayton) over 1 year ago

Jay, attics are a good place to wear a respirator----or at least a really good dust mask

Barbara, fortunately they don't live in the attic :)

Jim, yup I did

Shirin, I actually do not see them very often in the city limits-----just occasionally

Yvette, yes very good fertilizer

Amy---sorry about that :)

Alan, this one was not too difficult to figure out

Paula, sounds like calling a pest control operator would be a good start

Roy, yes, bats need to be kept out of the attic for sure

Lizette, most people get more wigged out by bats than the bats probably deserve :)

Kristen, there evidence is not that hard to spot once you know what to look for

Glenn, I am thinking of building one for my house

Wheatforbrains----I am sure you are batty

Bill, you are welcome

Don, yes they are great at keeping the mosquito population down

John, yes----they just need to keep them out of the attic

Craig, even the thought of bat guano is a smell I can do without

Mark, or squirrels mating, or rats mating or.......... :)

Jane, do try to keep it off your face :)

Leslie, my buyer walked from this one for much different reasons---this did not seem to phase them that much

Sue, it is cool to watch bats leave a house for the night----filling the sky with fluttering wings

Jack, with out bats there would be no analogy of "batty"

Posted by Charles Buell, Seattle Home Inspector (Charles Buell Inspections.com) over 1 year ago

In the case of the attic above, I got out of there before I had to take a breath!

Posted by Jay Markanich - Northern VA Home Inspector (Jay Markanich Real Estate Inspections, LLC) over 1 year ago

Charlie,

Usually the first tip I get to bats is a groddy area all around the soffit. Last time I saw that, good news, not attic access.

Posted by Steven L. Smith, Bellingham, Wa. Home Inspector (King of the House Home Inspection, Inc) over 1 year ago

Jay, I can see you disappearing like a bat out of hell :)

Steve, that was the case here too.
