Thanks for letting us know what happened, Deb. We're sorry to hear these pesky wasps keep coming back! For best results, spray the nest early morning or early evening when wasps/hornets are likely to be in the nest. As this is a surface spray, it's important to wait 24 hours to see results and then re-spray if needed. We'd like to talk further to better help. Please give us a call weekdays from 8 a.m. to 5 p.m. CT at 1-800-558-5252 and provide this reference number: 22602470. Looking forward to your call! – Mindi, SC Johnson Consumer Care
