When we once lived on your side of the water we seemed to keep on having problems with wasp infestations, (1) building nests in the loft, (2) garage and also (3) in between the bricks of the house under the kitchen window.
For problem (1) we called in the local exterminator experts who climbed up in the loft and sprayed some gunk around and then VERY QUICKLY fell back through the loft door stating ?Don?t go up there for a while mate!?
For problem (2) we took things into our own hands (joint venture on this one) and whilst I held the large bin bag Mr. Brave Barman knocked the nest into it and bish bosh job?s a goodun
For problem (3) Barman decided to solve it himself one day when I was out by filling up the holes in the bricks they were getting though with bath sealant!!!! Came back to hear loads of really p*****d off wasps humming around inside the bricks of the house and see loads of equally p*****d off wasps outside the kitchen window trying to get in to save those who had been Bathsealed????.
Have to hasten to add that none of these actions would have been taken if the offenders were those nice little bee thingy?s but wasps, YUCK, no good to man nor beast (that I know) so I don?t feel guilty.
