Grand total

Adult Vine Weevils just crawl around at night, chomping great holes in the leaves of your (mainly) potted plants and shrubs but they’re not the real problem, their larvae are.   

Vine Weevil larvae just eat, eat, eat away at your roots and juicy tubers and kill your plants. We know of at least one commercial nurseryman who has given up growing in pots, purely because of these Vine Weevil pests.  

Don’t worry though, that’s where Steinernema kraussei comes in to save the day… or at least your plants. Just mix with water (instructions included) and get it on your plants… asap.  

The rest is history, Vine Weevil history.
