We had very good experience with this company in the past, both with perimeter carpenter control and with mosquito control using essential oils.
This time, however, they used either the wrong concentration or the wrong sprayer; instead of a mist, huge amounts were sprayed in patches on top of plants. The leaves curled and turned black within half an hour (that is when I went out to check after the contractor left). Hostas, roses, rhododendrons, ferns, patches of grass. We just hope that the plants will survive and come back next year. It is sad. I give two stars because of previous good experience, this time, however, it was a disaster.
