The technician attending on 5/10/2022 - Barrie Finch - was most courteous, friendly and informative. He went up my ladder to confirm my visual of wasps entering via rooftop cavity. Donned his 'spacesuit' and injected Ficam D. Must have been over 100 angry wasps in a cloud, whereas before maybe 10 to 20 had been in transit. The blighters had obviously been having an inside mass construction. This morning, just a few late returnees, immediately buzzing off. Hope this second visit works. The initial visit on 26/09 was a failure. The technician would not go up the ladder, but injected the inappropriate powder from ground level. The wasps returned two days later and had obviously carried on where they had left off. You should amend your records to show wasps as the problem; the initial diagnosis of bees, as suspected by the operator during phone call for booking, was wrong. Two stars for initial visit; four stars for Barrie. Considering the upfront cost an eye watering £192 - later found a wasp hitman nearby who would charge £60 all inclusive - JG not deserving of five stars. Barrie says to wait 7 days. Report to JG if the blighters return for a third attempt at setting up home. God forbid! The whole ten days been very stressful pour moi. Am 77 and already have sky high BP.
