These guys are pros! Saw a few bees going in and out through the sprinkler valve cover in the ground in my backyard. I'm pretty observant and felt this activity could have only been going on for a day or two. Saw positive reviews on yelp and so I called The Beekeeper. Spoke to Richard at 4:30pm on a Friday and they would have had someone out within an hour if I wanted but I scheduled for the next morning. He was very knowledgeable and reassuring. Marino arrived the next morning right on time and quickly assessed the situation. He could tell by the weight of the valve cover that they had already built the honeycomb on the underside of the cover. He estimated they had probably been working there for a few weeks and that, by the time you notice them coming and going, they are probably already established. He quickly removed the honeycomb and treated the area. Unfortunately they could not be rescued but I felt confident in the natural solution used to eradicate them. And Richard had already told me not to worry because, while bee populations may be declining elsewhere, there are literally billions of them in Arizona. I was just glad to have it dealt with and so deftly at that. Marino instructed me to leave the cover on for another week or so and then seal it up. No more bees! Charged the price quoted even though Marino had to work around and very close to some cactus in pretty tight quarters. Very grateful to have the problem solved and would HIGHLY recommend these guys for your bee problems.
