Today I performed your Trelona termite bait station installation to the exterior. Soil areas to right side and front only. Back and left side all concrete. No liquid product can be applied sub surface due to pool close to the house. I placed Trelona bait stations in-ground to front landscape beds and lawn on right side close to concrete slab. See new graph for station locations. Thank you for choosing Green Pest Solutions!Signature on file. Payment on file.
