I have used squash [it's what I had] stick a fork in it and let it sit on the bottom and in the morning take out crush snails and feed to fish repeat the next night. Get any you see in tank or on glass till gone or to the population you want to be at.
Pleco wafers are my go to snail magnet. You can use a siphon hose without the bell to easily pull them up in a cluster or even individually. Caution: I use a siphon hose to change substrate too so be careful what you point it at.
