Best Suet for Bird Feeders: 7 Suet Cakes and Balls for Woodpeckers

The best suet for bird feeder use is a processed suet cake or ball that fits the feeder you already own and holds up to the weather you feed in. Our pick is the Wildlife Sciences Melt Resistant Suet Balls variety pack: 16 balls about 2.5 in across, in four flavors and four wrapped packs, with a melt-resistant formula according to the Amazon listing and Wildlife Sciences’ own product pages. Balls need a ball feeder, though one owner simply cuts them in half for a square cage. If you want square cakes, the other six picks below are cakes, and we say which suits which yard.

We compared the seven on shape and size, what is in them, how many come in a pack, what each listing claims about warm weather, and what owners report where a listing has owner reviews. Product details come from each Amazon listing or the maker’s own product page, and we say which. Feeding advice comes from Audubon, the National Wildlife Federation, Project FeederWatch, and Penn State Extension, linked where we use them, and where they disagree we say so and lead with the more cautious advice.

This guide covers choosing suet for backyard feeders. It is not advice on caring for sick or injured birds; if you find one, contact a licensed wildlife rehabilitator or your state wildlife agency.

Our Top Suet Picks for Bird Feeders

• Best Overall: Wildlife Sciences Melt Resistant Suet Balls Variety 16 Pack. Four flavors in four wrapped packs of four balls, the only suet balls here, with a melt-resistant formula per the listing and Wildlife Sciences.
• Best Bulk Pack: Wildlife Sciences Suet Cake Jumbo Mixed 20 Pack. Twenty cakes, 10 peanut and 10 berry, the most cakes and the most cake by weight of any pack here, according to the listing.
• Best Berry Blend: Heath DD-15 Berry Blast Suet Cake. The only pack here in which every cake is a berry blend, sold as a case of 12 no-melt cakes, according to the listing.
• Best Single Cake: Kaytee Suet and Seed High Energy Suet. The only listing here sold as one cake (11.75 oz, in its own tray), a low-commitment way to see which birds come.

Three cakes carry no title. The Wildlife Sciences Woodpecker cake (pecan pieces) and the Heath DD-24 Woodpecker cake (almonds and peanut parts) are both sold as woodpecker blends, per their listings, and nothing we could compare sets one ahead of the other, so neither takes a woodpecker title. The Heath DD412-10 High Energy Blend does not stand out on any detail we could compare, and one field of its listing names hot peppers as an ingredient while its title and description never mention pepper.

Figures come from the Amazon listing unless a cell names the maker. Sizes and weights are per piece. The Heath website has no product pages for individual cakes, so Heath details come only from the listings.

How We Chose

We searched Amazon US for suet cakes, suet dough, no-melt suet, multi-packs, and suet for bird feeders in general, and kept only suet itself, not feeders or seed. Each product had to be sold new, average at least 4.0 out of 5 from at least 30 owner ratings, and come from a brand on our reviewed list for bird food. Listings whose manufacturer field named a different company than the brand on the label were removed, except where we confirmed the manufacturer is the brand’s parent company, as with Kaytee. We kept no more than three products from one company, which is why there are three each from Wildlife Sciences and Heath. Two more listings titled as Wildlife Sciences cakes were left out because the brand name on them is one we could not confirm belongs to Wildlife Sciences.

For the top spot we prefer a product from a brand we have vetted with at least 1,000 owner ratings and an average of at least 4.2. Best Overall goes to the Wildlife Sciences suet balls, a product that met every one of those bars and that Wildlife Sciences still shows on its own site in four-ball wrapper packs. The other six follow in our research ranking. The FeederBirdLab Score on each card is a separate measure, explained in our scoring method, and does not set the order. Where we could find a maker’s product page, we compared it with the listing. The listing for the ball variety pack gives 16 oz for all 16 balls, while Wildlife Sciences gives 1.0 lb for each four-ball pack, so we lowered that product’s FeederBirdLab Score by 0.2; the Wildlife Sciences cake pages give 11 oz where the listings say 10.5 oz, a small gap that did not change a score. Our full method is on the How We Review page.

How to Choose Suet for Bird Feeders

Suet is worth offering because it reaches birds that seed alone may not. Project FeederWatch calls suet a good choice for attracting insect-eating birds, and Audubon’s feeding tips name woodpeckers, wrens, chickadees, nuthatches, and titmice. These are the choices that separate one pack from another.

Match the shape to the feeder you own

Start with the feeder, not the flavor. Six of the seven are cakes, and the five with a size given by the listing or maker are about 4.5 to 5.25 in square: about 4.5 x 4.5 in for the Wildlife Sciences Woodpecker cake, 5 x 5 in for the Jumbo Mixed cakes and the Kaytee cake, and 5.2 to 5.25 in for the two Heath cakes whose sizes are listed. A cage built tightly around a 4.5 in cake may not close on a 5.25 in one, so check the inside of your cage before you buy a case. If you are still choosing a suet feeder, buy it and the suet together so the sizes match.

The Best Overall is a ball, about 2.5 in across, and it is made for a ball feeder. Wildlife Sciences sells ball feeders of its own, and owners of this listing say the balls fit their holders; one owner instead cuts them in half to fit a traditional square suet holder. Kaytee’s page gives its 11.75 oz cake as 5 x 5 x 1.25 in, in a tray that slips into the Kaytee Feeder Station, so it suits a cage sized for 5 in cakes but not one built tightly around a 4.5 in cake.

Processed cakes, not raw suet

FeederWatch explains that most suet is beef kidney fat sold at meat counters, and that suet also comes as processed cakes that include seeds, berries, and other ingredients. All seven products here are processed cakes or balls. The two Wildlife Sciences cake listings and Kaytee’s product page put rendered beef suet first in the ingredient list; the Heath listings give flavors and a few ingredients but no full list, so read the package if you want to know what fills a Heath cake.

Warm weather: read melt claims as the seller’s word

Audubon’s feeding tips limit suet to cool weather, while a National Wildlife Federation article allows all-weather suet in the shade during hot spells; we follow Audubon by default. If you shop with summer in mind, six of the seven listings make a melt claim (no melt and all-season on the three Heath cakes, melt-resistant formula on the three Wildlife Sciences products), and that is the seller’s word, not a rating; the Kaytee listing makes none.

Read the ingredient line for who it will draw

Most cakes are suet mixed with grain, seed, nuts, or fruit, and the mix changes the guest list. Four products name corn, and two of them millet; FeederWatch says cracked corn draws doves, quail, and sparrows, and millet draws juncos and sparrows. One Wildlife Sciences Woodpecker owner lists sparrows among the birds at that cake, alongside woodpeckers, wrens, and chickadees. Nuts appear in four products: peanuts in all four ball flavors, per Wildlife Sciences, and in the Jumbo Mixed cakes, pecan pieces in the Wildlife Sciences Woodpecker cake, and almonds and peanut parts in the Heath Woodpecker cake. The Insect and Nuts balls add dried mealworms, which Wildlife Sciences says attract tree-clinging and insect-eating birds. Berry flavoring is the selling point of the Heath DD-15 and half the Jumbo Mixed pack.

Two products include hot pepper: one of the four ball packs is a Hot Pepper blend that, per Wildlife Sciences, contains chili pepper oil to deter squirrels, and one field of the Heath DD412-10 listing names hot peppers. FeederWatch says squirrels and other mammals may be put off by capsaicin, the compound that makes peppers hot, but that it knows of no research on the effect of high doses on birds and discourages adding products to bird food without thorough research behind them. The same caution applies to hot pepper bird seed. If that gives you pause, use the other three ball flavors and skip the pepper pack.

Buy a pack size your birds will finish

Pack sizes here run from one cake to 20, and by the listings’ weights, from 11.75 oz for the Kaytee cake to about 210 oz for the Jumbo Mixed pack. How fast suet goes depends on your birds and the season: one suet ball owner says a four-ball pack can last a day or a week, depending on the time of year. A first-time suet feeder does better starting small, with the Kaytee cake or one ball pack, and moving to a case once birds are coming daily.

Plan for the visitors you did not invite

Owners of both listings with reviews report starlings at them: one suet ball owner names Common Starlings among new visitors, and one Woodpecker cake owner says the starlings seem well fed. If they are already a problem in your yard, plan how to keep starlings away from your suet before you buy a case. Mammals come too. One Woodpecker cake owner says raccoons and deer go after it as well, and another says the crumbs that fall are eaten by squirrels and chipmunks on the ground. Before you stock up, decide where to hang the feeder so raccoons and deer cannot reach it.

Who Should Look Elsewhere

If you want to feed suet through hot summer weather, our default, following Audubon, is to pause until it cools. If your yard draws mostly finches, sparrows, and cardinals at seed feeders, compare suet with bird seed before buying a case: FeederWatch calls suet a good choice for insect-eating birds.

Within this list, skip the suet balls if you own only a square cage and do not want to cut them, and skip the Kaytee cake if your feeder is not a Kaytee Feeder Station and your cage is built for 4.5 in cakes. Skip the Hot Pepper ball pack and the Heath DD412-10 if you would rather avoid capsaicin until there is research on it. And if sparrows already crowd your feeders, the corn and millet in four of these products may draw more of them.

Suet for Bird Feeders FAQ

What is the difference between suet cakes, suet blocks, and suet balls?

In these listings, suet cakes and suet blocks describe the same kind of square slab of processed suet; the cakes here run about 4.5 to 5.25 in on a side and are made for a square wire cage. Balls are round, about 2.5 in across for the Wildlife Sciences balls, and are made for ball feeders. Both are processed suet mixed with other ingredients.

Are bird seed suet cakes the same as plain suet?

No. FeederWatch describes plain suet as beef kidney fat and processed cakes as suet that includes seeds, berries, and other ingredients. Every product here is the processed kind; the Kaytee cake, for example, lists rendered beef suet, corn, white millet, and black sunflower, per Kaytee.

Does a no-melt label mean the cake will not melt?

Not necessarily. “No melt” and “melt-resistant” are the seller’s descriptions, not a rating from a bird-feeding source, so hang the cake in shade and take it down if it softens or drips.

What suet is best for woodpeckers?

Penn State Extension calls suet particularly attractive to woodpeckers, and two cakes here are sold as woodpecker blends: the Wildlife Sciences Woodpecker cake with pecan pieces and the Heath DD-24 with almonds and peanut parts, per their listings. One Wildlife Sciences Woodpecker owner reports three kinds of woodpeckers at it; the Heath listing has no owner reviews we could use.

How long does a suet cake last in the feeder?

It depends on how many birds feed and the weather. One suet ball owner says a four-ball pack can last a day or a week, depending on the season. Whatever the pace, FeederWatch advises cleaning suet feeders every week or two, and more often in heavy use or wet weather.

Final Thoughts

• Best Overall: Wildlife Sciences Melt Resistant Suet Balls Variety 16 Pack
• Best Bulk Pack: Wildlife Sciences Suet Cake Jumbo Mixed 20 Pack
• Best Berry Blend: Heath DD-15 Berry Blast Suet Cake
• Best Single Cake: Kaytee Suet and Seed High Energy Suet

Pick suet by the feeder you have first, then by the birds you want and the weather you feed in. Match ball to ball feeder and cake to cage, start small if suet is new to your yard, and take it down when the weather turns hot. More seed, suet, and food guides are in our Bird Food section.
