Because DE kills them mechanically, they cannot become immune to it like they do with so many of the chemicals today.

My feeling is that milder climates have an overall lower percentage than harsher environments.

The patent, of course, was a public record but the key to that business was to put together a team of professionals (chemical engineers, scientists, etc.) and take them to India from the U.S. and then help the Indian manufacturers make generic versions of the drug.

Without a doubt, people vary in their chemical sensitivity.

Have plenty of ventilation or a chemical filter mask while using both the clove and the sealer.

If all goes to hell, I still have a 9-5 that pays well and a degree in chemical engineering.  

I'm absolutely not experienced, nor a professional in this, but I have heard rumors that due to the chemicals, it could be enough to condemn or make the property inhabitable.  

I currently work a full-time day job as a chemical engineer (shout out to Andrew Cushman from BP podcast episode 170), but I'm planning to eventually transition into real estate investing full time.Short-term, I'm interested in spec home building, as well as fix-and-flips, but eventually would like to change over to a buy-and-hold strategy involving multi-family properties for the long term.

Payments are just over $1,300/month. pool service, $100 projected( have done the chemicals initially myself), landscaping free, all desert scaping, not much work to do.

I had mine done on my recent rehab (granted it was really bad) it was chemically cleaned it cost 450.
