Another thing that can really put the hurt to traps, especially fragile ones, is a determined feed trained snapping turtle of size.
Do snappers eat pellets? I've not witnessed it (yet?)
Half acre 30 year old farm pond, Mebane NC. Aeration & feeder. LMB, CC, SC, BG, HBC, two no account welfare carp and nine seasonal Tilapia that all the other fish are terrified of.
