Pond Boss Forums MANAGING AN EXISTING POND Corrective stocking Bullhead / Stunted Bluegill

It does sound like the openings are too large. Add something below and above the bait in the cloverleaf. I like using the top and bottom of plastic half gallon milk jugs. This keeps BH from a free meal. Keep plenty of bait in the traps. If they are not eating they will be trying to find a way out. I use old socks with holes just big enough to let some bait come out. 20-30 holes. Cheap dog food is greasy. I use the multi fish food from Tractor Supply. It is about .50/lb. Add bait every other day. When it smells rotten, dump the bait. Try setting the traps near each other about 5-6ft deep. You will catch fewer other fish. Check traps daily if possible.
In the last year I've removed 2000+ BH YOY via cloverleaf traps.
