What's in Nippon powder? Is it plain permethrin or (like the liquid)
mixed with something sweet to entice the ants into taking it indoors?

I've got some here ...

/me tastes a bit

Nah, it don't taste sweet.

*thud*

Ah opps, should have looked at

Talcum base, Permethrin 0.5%

Think I'll live :-)

Surprisingly quick knockdown of Wasps if you can get the powder in the
right place.

We have horizontal gutter board and they find their way in to the eaves
through gaps between that and the wall boarding.

Homebase do Ant powder in 500g packs but squirting powder uphill does
not work. The D-I-Y solution has been a short length of Bundy tube
fitted to the opened out hole in the dispenser.
