I use strictly no melt suet. Birds love it and no mess in my heat.![]()
I get the no melt suet too. I don't go through it as fast during the summer as I do in the winter though.
I buy the Unipet Suet To Go pellets and just feed the birds it as and when rather than put a load out (which disappears in seconds anyway!). The suet cylinder blocks I did buy once or twice but that was in the winter and only rarely as they were pretty expensive.
The one time I filled a feeder with suet pellets the morning I was preparing to leave for a holiday they'd eaten the lot before I left the house! A whole feeder emptied within an hour and a half! Wouldn't go off in the heat at least...![]()
