Hi everyone, any advice please on keeping slugs out of a ground level wooden sandpit? It has a wooden lid and we put a cover under that too but the blighters still gets in. Seeing slug poo on the buckets etc made me a bit weary. Its a bottomless wooden sand pit but the sand is on a liner on top of the ground and it has a roof canopy. I'll keep toys hung up in a net and change the sand once a year but any tips welcome. 🤷🏻♀️ tia x
