CastClear Lawn Worm Cast Suppressant

£19.99 for 500ml


A spray to reduce the number of wormcasts on your lawn for up to 20 days.

The chemicals break down into nutrients absorbed by the grass. A 1-litre bottle contains enough worm deterrent to treat 100sq m of lawn from September to March, when  the worms are most active.


Personally, I’d put up with the casts to keep worms busy in the lawn, but if you’re fed up with muddy shoes, it might be worth deterring them. You’ll need to dilute this and use a large sprayer to get a blanket application. I counted the worm casts on my lawn, sprayed half and left the rest untreated. It’s not harmful to children or pets (or worms), but smells bad and lingered for a few hours. After a week, there were a handful of new casts on the treated lawn, but it looked greener and less muddy than the untreated half, which had more than 70 new casts. CastClear claims it will deter worms for up to 20 days – we’ll update you on how long it lasted in a later issue.

March 2013 Issue



Lawn Wormcast Suppressant

In the last issue we reported on CastClear worm repellent, which is said to reduce the number of worm casts on your lawn for up to 20 days. We found that it was 17 days before the worms in our garden returned fully to the treated side of the lawn.
