Testimonials for NO Wasps Eliminator

I noticed a wasp nest entrance under the apex of the terracotta tiles of what we call the garden shed.
It was very active and high up.
I watched it for several nights and noticed that it was totally quiet just as the light was fading.
The problem was access.
I looked around at what I had and finally produced a perfect gadget that delivered a precise amount of wasp eliminator into the hole while standing 2 M away.
I tested it using talcum powder in another part of the garden.
Last night on dusk fired about 10gms right into hole.
This morning not a single wasp in sight, and a trace of powder round the entrance
A totally clean way of doing the job with reduced risk.
Thanks for your brilliant product.
