Sorry for the delay in writing this review, but felt obliged to wait until I was sure we had seen the last of the ants! Having become used to the nuisance of them in our kitchen, it has been a pleasure not to have been "invaded" as we have in previous summers. We still experienced significant activity outside at the base of the kitchen wall and under the back doorstep, even after the first visit, which was the reason we asked for a follow up one. The second application must have had a greater effect on them as there was very little evidence of ants subsequently. Over the whole Spring/Summer I only saw maybe 4 or 5 inside our house, so you can imagine how pleased we are with your service. Your response was very prompt and the professionalism and courtesy of both technicians and support staff was beyond reproach. Thank you very much!
