Maybe better you did not. Suspect: Bat guano bacteria in the feces releases pathogens into the air.
I always enter attics with PPE. or at least, a full face mask/respirator. Silicone Full-Facepiece Mask Respirator
Recommend a licensed IAQ assessment and remediation.
Must have been one of these.
“We also provide abbreviated, ‘Walk and Talk’ inspections. Quick walk thru inspections to give you a general overview of your potential investment.”
Yep. It should be covered. Here is another source if someone wants to supplement the photo of the actual warning printed on the kraft paper or if it is faded.

I concur, Jeffrey.
This is a limited commercial inspection. No testing, no ladders, etc. It’s understood that we will not be putting on masks, etc., or entering any area we feel not save without extra protective equipment.
Thank you!
With all of those limitations and your initial thought that it is mold, are you recommending that the client pay for a second inspection to determine what it is?
No testing for microbial growth I get.
You where there. It was, by the looks of it, a insulated knee-wall making this within the envelope.
PPE is a minimal safety requirement.
Residential SoP.
3.9. Attic, Insulation & Ventilation
I. The inspector shall inspect:
A. insulation in unfinished spaces, including attics, crawlspaces and foundation areas;
B. ventilation of unfinished spaces, including attics, crawlspaces and foundation areas; and
C. mechanical exhaust systems in the kitchen, bathrooms and laundry area.
II. The inspector shall describe:
A. the type of insulation observed; and
B. the approximate average depth of insulation observed at the unfinished attic floor area or roof structure.
III. The inspector shall report as in need of correction:
A. the general absence of insulation or ventilation in unfinished spaces.
IV. The inspector is not required to:
A. enter the attic or any unfinished spaces that are not readily accessible, or where entry could cause damage or, in the inspector’s opinion, pose a safety hazard.
B. move, touch or disturb insulation.
C. move, touch or disturb vapor retarders.
D. break or otherwise damage the surface finish or weather seal on or around access panels or covers.
E. identify the composition or R-value of insulation material.
F. activate thermostatically operated fans.
G. determine the types of materials used in insulation or wrapping of pipes, ducts, jackets, boilers or wiring.
H. determine the adequacy of ventilation.
Yup… it reads to me like a “Field Services Walkthrough/Verification Survey” that limits these issues so they don’t have to pay the Inspector a Real fee!
Hi Robert,
Looks like Cockroach poo from here in GA. Did it have a unique sweet type smell/odor?
well then it really wasnt much of an inspection …I saw no mold it Your picture but I spect that stuff tasted like sh,t
LOL, I got a good chuckle out of that.
It’s cockroach poop. We see it all the time down here in Alabama. It comes from those 1 inch long or longer roaches/water bugs that are also capable of flying. If you google “cockroach poop” and look at the images you’ll see it.
Based on the available photos, it’s definitely not mold. It looks, both in size of droppings as well as position of droppings, like these seem to be relatively recent bat droppings from night roosting, not nesting. More accurate and closer photos would’ve been helpful.
Please find some helpful information in the video below. (If indeed it turns out to be bad guano)
Good Luck to you!
Very helpful. Thank you.
Thank you!
This will be up to the seller or client. We would recommended having a licensed pest inspector be retained for further evaluation. You get what you pay for, that’s why the scope is different. Not required to move or rearrange equipment or stored items to gain entrance or a better a view.
Thank you! This was not a residential inspection.
