Kill Slugs

Simply and Efficiently

The key to successful slug control is down to the quality of the bait. Bait quality is determined by four characteristics:


To achieve a uniform spread a pellet needs adequate mass and consistent density. The larger the pellet the greater its mass and the greater the energy that can be imparted to propel it. This is why larger pellets spread better and why a cricket ball can be thrown further and with greater accuracy than a table-tennis ball. It’s a question of size – and size matters!


The essence of a successful slug pellet is that it is more attractive to slugs than the seedling is. Our ferric phosphate enhanced wet process pellets use food-grade durum wheat flour together with carefully selected attractants which are unique to our range. Slugs are discerning eaters so it is no surprise that they find this combination so appetising.


Using a palatable high quality durum wheat pellet simply ensures the slug ingests sufficient of the active substance to cause death. The pellet must be soft enough to be edible, but not so soft that the slug can rasp though it before the intoxication process takes effect, or else the slug could ingest the entire bait, and then continue to graze on plant seedlings. Our pellets are engineered to meet these essential requirements.


Efficient and effective control requires using a pellet designed to last several weeks, and our larger pellets can withstand the rigours of environmental exposure in the field, and deliver effective control over a prolonged period of time.
