We have a wasp nest in a very awkward position. It is in the side top of the roof above the porch. I have attached some images showing where the nest is.
There is a window next to the nest but not very close, it would be a struggle to get some powder down the hole.
What would be the best substance to use to kill the wasps (e.g. powder, spray) and what is the best way to access it, walking onto the roof would not be ideal.
Thank you!
I have to say I would not hesitate to call a pest control company to do it for you - they will deal with it efficiently, rather than you struggling to do it and not doing it very well, especially as that's an awkward access area. Pest Control companies are still allowed to operate at the moment in the UK, though they may not all be working - ring round and get quotes.
Purchase the wasp/hornet killer that has a 20' stream spray. You should be able to blast the nest from a ladder without having to get in a position where you cannot escape the potential swarm of angry wasps. And wait until late evening or night; this is when they should all have returned to the nest and when they are less active.
Not an endorsement, there are many brands.
Also, there are extension arms to help reach remote nests:
