Quality Bird Suet?

I've found with suet especially that buying from a specialty place like Wild Birds Unlimited makes a difference. I just stopped buying it from any of the big box joints. There's also a decent feed snd seed store near me that carries good stock that doesn't seem to sit around. I don't have a brand right now, though.

How about a seed cake? I use the one with dried mealworms, seeds, etc. and capsaicin oil ( Mr Bird’s Flaming Hot Feast) so the squirrels won’t eat it.

Heath Almond Woodpecker suet is what we buy via Amazon. LINK
But if your suet lasts more than a couple of days, something is wrong. Put out less or change types/brands.
Our suet disappears in a day or two.
