I used Cain a few times for wasp nest treatments around and on the outside of my home. Carlo personally did the treatments and returned to treat another nest the same summer - under his "one year warranty" even though it was clearly a new nest in a new location.
I recently had a bed bug scare - Carlo was at my house within a few hours and checked the bugs I'd found (luckily NOT bed bugs), thoroughly checked all beds in the house, AND did not charge me as he said he was in the area. Many companies would have continued with the treatment and charged me for it. He was very understanding and very professional. I would recommend him to anyone.
I'm sure I'm not done with various critters and pests - but I know who to call to make it all OK.
