I'm very disappointed, My client had an ant and a rat problem. The ants kept on coming back, as for the rat problem they used glue traps for a mouse size not a rat size. The first tech was horrible he just sprayed and did not even check behind the oven and under the sink for setting rat traps the only used medium size mouse glue traps!!! For rat problems you use rat traps!!! Very disappointed!!! They would rather blame the customer that hired them and not evaluating the rat problem !!!!
