I have wasps in my eavestrough over my breakfast room so it is accessible. I have sprayed inthe openings where i could see the wasps entering but it did not work. I sprayed again and sealed the entrances with caulking but they always seemed to find another entrance. As you know the underneath of eavestroughs have air spaces and it seems that unless I seal all the joints and holes they will continue. Is there any other method?.
Thanks John Coffey
