5 Star Review

I first came to appreciate Garella many years ago. They already enjoyed a stellar reputation; a reputation that allowed me to use them to shut down very unscrupulous actors claiming to be in the same business. I was in law enforcement at the time and we became aware of a “fly-by-night” group that was planting insects and other pests in the attics of homes owned by elderly women. These crooks were using scare tactics. Our police agency combined forces with Garella and essentially created a “sting” that put the “bad guys” in jail.
