I’ve got a clay paver patio that’s been down for about 30 years. I’ve jet washed it, replaced the odd damaged block and remanded with kiln dried sand. Next summer I plan to do another quick wash and sand before applying a flexible resin sealer to fix the sand and prevent weed growth.
However I’ve got loads of worm casts all over the patio. The gaps are a minimum of 2mm as all the blocks have spacers cast on the sides, up to 6 or 8mm where the blocks have moved over the years. If I sweep it off they are all back the next morning.
ideally I would like to bring the worms to the surface so I can catch them and move them down the garden. Alternatively apply something to deter them from coming up through the sand. The final solution unfortunately would have to be to apply something to poison them.
Has anyone had a similar problem and how did you resolve it?
Thanks
Brian
