I'm going to bring some samples to the DIY store and they'll look at them under the microscope.I also read about those Co2 things and I'm trying to find where I can buy them, as I've seen some +$ 900 ones and am not prepared to get that, yet....May have to ,if I can't eradicate some other way

The City of Independence stated that they have been trying to get USREEB to fix the issue for almost 2 years & I was never even notified of such issue.The tenant moved out Aug 2017 & the property management company kept charging me utilities upwards of $400 when the property was vacant & did not/could not provide me proof or answer why.The bottom of the kitchen sink cabinet was missing & had fungi growth that was never cleaned and replaced.
