Discovered wasp nest in the morning and immediately rang The Pest Control Co who gave me a price and advised that Alan would contact me later that morning to arrange a visit. Alan duly rang as promised and advised he would be with us at 12.30 pm. At exactly that time Alan arrived and after I showed him where the wasps were entering the building he explained exactly what he was going to do to get rid ofthe colony. After entering the loft to determine the size of the problem, on his return he confirmed the nest was the size of a small suitcase. He then kitted up and sprayed the nest with chemicals. He then repeated the process on the outside of the house using a long tube entering through the eaves. Alan advised that within 24 hours all the wasps were likely to have gone and sure enough one day later we were back to normal. Thank you Alan for a job well done.
