All you can do is to watch out for wasp activity, and PLEASE be careful - angry wasps might attack you!

They are very persistent and it may take a few sprays - try to see if there are more than one entrance/exits and spray all of these that you find. It took over a week of spraying the entrances to the nest I had last year before they dissapeared. Hopefully your spray has a sort of extension pipe so you dont have to get too close. As Spritz says be careful, they are nasty when roused.

if its at ground level its worth shuttering the hole so it holds water at night ofcourse and fllod it out at night . you know if youve killed them as they will leave and come back to the nest strate away in daytime .

Thank you all. No sign of them over the last few days so fingers crossed they have gone.

sorted it seams . you would of seen them bye now for sure . what seams like a few wasps can turn into quit a few if you block the entrance of and they would be in and out as usual easily bye now .

if you spread a wasp killing powder at the entrances to the nest the wasps will contact it and take it into the nest as they come and go and so be killed.when activity is seen to have stoped you can dig out the nest and the wasp pupae present are much saught after by fishermen

Thank you Emerge. There doesn't seem to be anymore activity at the moment but I am keeping watch and will certainly try the powder if they return.
