I've used this company in the past for spraying my birch tree for birch leaf miner and had OK results. After taking a year off, I called them to return with the same service and a spraying service for ants, mosquitos etc. 2 weeks after they sprayed I contacted by phone telling them my problems were not rectified. No one returned my call ,in fact, I called again asking for the manger and was sent an email confirming that they'd return a call and still no one has! Product doesn't work and neither does the company!
