Very large apartment building (24 stories, hundreds of units) was badly infested with cockroaches, and the building hired Citron to bait and spray. Their technician, Brandon, was incredibly personable, professional, and provided vital information to help us get rid of them completely and prevent moving them to the next place we moved to. After the first spray treatment, we only found corpses; no live roaches at all. The products they use work well, and the customer service was invaluable. They clearly care about educating the customer to stop current infestations and prevent future ones, even though that essentially would put them out of business.
