The only way to get rid of it for real is to remove the insulation that the guano is piled on. Also, you'll need to scrape/disinfect the permanent structures (beams, floor boards, etc) that the insulation was laying on. And, you must wear breathing protection to keep the mold spores out of your lungs.
It's sad but true-- it's an expensive, time consuming process.
My knowledge comes from talking to experts when my MIL had the problem in her attic, gleaning the internet for less expensive/diy solutions and direct visual contact with a "guano"load of guano and the insulation/floor boards the guano had piled up on.
Be reassured, there is no guano in Oreos.

There is no actual "Guano Island". There is a Guano Island Act, which is a federal legislation passed by the US Congress on 18 August 1856. It enables US citizens to take possession of islands containing guano deposits. Guano is the droppings of bats, seabirds, and seals. It is a highly prized fertilizer.

the guano islands act
The production decline in guano islands was due to overharvesting of the guano, which led to depletion of the resource. Additionally, competition from synthetic fertilizers made from ammonia contributed to the decline in demand for guano. Regulations to protect seabird populations also limited harvesting on some islands.
