I have always had a big slug problem here, lots of mulch ,organic matter etc
Provides good habitat.
I have used the iron phosphate in propagation areas, but it can be expensive .
Last year I came across an "old "article from I think the USDA on slug control,
Using hydrated lime dust.
I put some hydrated lime in an old garden duster with an extension pipe on the discharge and gave it a worl under some seed flats that were being eaten.
The slugs came out like they were on fire, but did not make it far.
Just a very light film of the dust was enough to make them give up all their slime, makeing it only a few inches befor they could move no more.
Was “almost” enough to make you feel sorry for them.
As the soil is acidic here, lime is ok.
The amount I used is very small, just a barely visible layer of dust.
Do not breath the dust , or get in eyes.
Pickling lime comes in small sizes in the grocery store works well.
So last year I wooped them
And I am not sharing my beer with them as some people do !
