Did stand-alone treatment using Rossi Gel at a cancer patient’s house in Reservoir Hills for cockroaches. Infestation was extremely heavy. Client’s daughter contacted us with much relief and excitement with the outcome of results of stand-alone treatment done with Rossi Gel. She says infestation cleared out in a week, they were doubtful at first that a small tube of gel will help. After seeing the results they now know the effectiveness of Rossi Gel. This is the second stand-alone treatment done with Rossi Gel. The other client was in Riverside and was also very pleased with the results after application of Rossi Gel. Excellent product. Will highly recommend it for stand-alone treatment. Very cost effective.
