I needed a wasp nest taken care of. The nest was 30 feet in the air and inside my exterior wall. Contacted a few companies and because of the nest being higher than 10 feet a few of them was charging extra ($50 to $75 more). I contacted Green Valley and they quoted me a flat price regardless of height. Ernie came by to spray the nest and said to give it a 3 or 4 days and if they are still active to give him a call. Since he went up to the roof he also told me that their was 5" of standing water on my flat roof. Discovered that the downspout was clogged. Thanks to Ernie I would have know about my other issue which could have caused me more money in the end for repairs if he didn't go up on the roof. Back to the Wasp nest, after a week, I noticed that the wasps are still flying in out of the nest. I called Ernie and told him about it and within a few days he came back and this time he said it's should be taken care of. Within the next day there were no more wasp activities. I believe that I paid a fair price and Ernie at Green Valley took care of the nest. To be fair to him, he probably couldn't access the nest on his first try because of the standing water on my roof. Once the water was gone he was able to access the nest better this time around. I recommend Green Valley Pest Control for your extermination needs.
