Practical Pelleting Advice 

Treatment Thresholds 

Treatment need should be confirmed by using traps prior to cultivation when the soil is moist and weather warm.

Spread around two heaped teaspoonfuls of chicken layers’ mash on the soils and cover – using a plastic dish or plate about 25cm (12”) across.
Set around 9-10 traps per 20ha field – more in larger fields.  Leave them overnight and assess damage.

Trapping between drilling and emergence can be worthwhile in wet weather.

In winter wheat, CONSIDER applying pellets if more than four slugs/trap are found and weather conditions confirm a risk.  Continue monitoring up to early tillering.

In oilseed rape, CONSIDER applying pellets if one slug or more is found/trap on the preceding cereal stubble if weather conditions are conducive to damage.  Continue monitoring to the 4-true leaf stage.

In vegetables, CONSIDER applying pellets if slugs are found in traps at the early stages of establishment or after transplanting.  Take care that pellets are not lodged in harvested plant parts.

DO NOT USE SLUG PELLETS IN BAIT TRAPS – with run-off or leaching these can add to significant point source contamination.

Another simple method of identifying a risk is to spread one bout of metaldehyde pellets across the field and inspect the treated area on the following morning to assess slug activity. This also allows for an assessment of the spread pattern and total width to either side of the spreader.

Pellet Application

Applications are not needed and should not be made to grass strips, hedgerows or areas adjoining water courses.  

Treat these as buffer zones and only protect the growing crop, pelleting this and not the field margin.

- Only spread pellets if you have a Certificate of Competence see www.nptc.org.uk for further information
- Only apply pellets if thresholds are reached and weather conditions indicate a crops risk
- Always wear appropriate pesticide application clothing
- Calibrate your spreader to match product and rate
- Don’t apply pellets to grass strips, hedges and ditches
- Don’t apply pellets if it is too windy or is heavy rain is expected
- Always clean up spills – immediately
- Dispose of packaging through a licensed waste contractor
- Avoid pellets falling within 6 m of the top of a watercourse


Slug pellets are pesticides
Don’t spread if you can’t spray
Keep pellets out of surface water and watercourses.
