Customer kindly sent these pictures for us to help plan ahead. Wasps nest this late in the season can be large and can be aggressive. More so mid September onwards as they get more and more aggressive. It won't be long until we start seeing the Queens emerging from these nests 150 to 350 per nest, which will be the Queens constant next season. They will find places in sheds, wood piles attic etc to hibernate. Do not let a colony just be, if its in your property deal with it professionally early. Call HERDpesontrol on 01333 771000 and arrange your visit.
