Best wren houses

Wren boxes are the cheapest way into nest boxes and the easiest to get wrong, because almost every decorative birdhouse sold is nominally a wren house and almost none of them publish a hole diameter. That single number is the product. Everything below is either NestWatch's published specification or the maker's own, read on the dates in the sources — we have not handled these boxes.

What we judged on

1. The entrance hole, to the eighth of an inch. It decides the species, and it decides whether House Sparrows can get in and take the box over. This is the first specification on every product here.
2. Whether there is a predator guard. A plain hole in 3/4 in cedar can be chewed wider by a squirrel in an afternoon, which turns a wren box into a squirrel box permanently.
3. Whether the box opens. Old nests have to come out between seasons. A flip-up front or a swing-open panel is what makes that happen; a sealed decorative box does not get cleaned.
4. Drainage and ventilation. Both published by this maker, and both are the difference between a dry brood and a failed one in a wet spring.
5. What it is made of. Cedar with stainless screws lasts; pine with nails loosens. Recycled HDPE never rots at all. All three are on this page and all three are honest trades.
6. What the maker publishes at all. Kettle Moraine publishes hole size and external dimensions on two of these three and hole size only on the third. Nobody in this class publishes an internal floor dimension, which is the figure NestWatch actually specifies.

Ranked for a yard that wants wrens and chickadees and has had a box chewed at before. If nothing has ever damaged a box, the plain cedar version at the bottom does the same job for six dollars less.

Pick 01

The same box with the two things the cedar version lacks

Kettle Moraine Wren & Chickadee Nest Box with Recycled Roof

Identical cedar body and 1-1/8 in hole, plus a recycled-plastic roof and a predator guard — the version to buy if anything has ever chewed a box in your yard.

Published specifications

The published requirement for a House Wren box

NestWatch specifies a 5.5 in x 5.5 in floor, a 1 in entrance hole, an 8 in inside depth, mounting 5 to 10 ft above the ground, boxes about 100 ft apart, any orientation, and a position within 100 ft of woody vegetation with clear flying room at the hole.Source: NestWatch (Cornell Lab of Ornithology), House Wren nest box specifications, nestwatch.org, read 2026-09-27

What it gets right

• A predator guard for six dollars over the plain cedar box is the best-value upgrade on this page
• The recycled roof is the part that takes the most weather, and plastic does not split or need treating
• Same published dimensions as the cedar version, so nothing is traded away for the upgrade
• Five color options, which matters only because a box you like the look of is a box that stays up

What it does not

• A plastic roof on a cedar box is a mixed-material object and looks like one
• Still a 1-1/8 in hole rather than NestWatch's 1 in House Wren figure
• One colorway was unavailable from the maker when we checked, so the color you want may not be the color you get
• No published internal floor dimension, same as the cedar version

Who it is for

Anyone in squirrel or raccoon country, or anyone replacing a box whose entrance hole has already been chewed open.

Skip this if

You want the box to be all wood. This is the practical version rather than the handsome one, and the all-cedar model costs less.

Pick 02

A wider hole, for the species a wren box shuts out

Kettle Moraine Recycled Nuthatch & Titmouse Nest Box

A 1-1/4 in copper portal and a fledgling ladder, in recycled milk-jug lumber — built for nuthatches and titmice rather than wrens, and it says so.

What it gets right

• A copper portal is the most durable entrance treatment here — squirrels cannot chew metal
• The fledgling ladder is a detail aimed at whether the young get out, not at the buyer
• Recycled HDPE does not rot, split or need treating, and this is the only box here made of it throughout
• Names the species it is designed for, and the ones it also suits, rather than claiming to fit everything

What it does not

• A 1-1/4 in hole is at the size where House Sparrows start to become a problem, which the smaller boxes here avoid by design
• The maker publishes no dimensions at all for this model, which the cedar wren boxes do
• The most expensive box on this page, for a hole size some yards specifically do not want
• Two of five colorways were unavailable from the maker on the day we checked

Who it is for

Someone who has nuthatches or titmice around and wants a box sized for them rather than a wren box they will ignore.

Skip this if

House Sparrows are already a problem in your yard. The 1-1/8 in boxes on this page exclude them by geometry; a 1-1/4 in hole does not.

Pick 03

The straightforward cedar box, at the lowest maker price here

Kettle Moraine Wren & Chickadee Nest Box, cedar (for mounting)

Solid cedar, stainless screws, a flip-up front and a 1-1/8 in hole — the plain version of a box that does not need to be complicated.

What it gets right

• The floor area and depth sit close to NestWatch's published House Wren figures, which most decorative boxes do not even publish
• Cedar and stainless screws rather than pine and nails — the difference between a box that lasts a decade and one that loosens in three winters
• A flip-up front means it actually gets cleaned out between seasons, which matters more on a wren box than most
• Cheapest of the three here at the maker's own price, and it needs nothing else to go up

What it does not

• No predator guard, so the entrance is a plain hole in 3/4 in cedar
• 1-1/8 in is a chickadee hole rather than the 1 in NestWatch publishes for House Wren specifically
• The maker does not publish an internal floor dimension, only the external size
• Cedar will gray over, which is a look rather than a fault but worth expecting

Who it is for

Anyone who wants a properly built small-cavity box, in a yard with woody vegetation nearby and no history of squirrel damage.

Skip this if

Squirrels chew at your boxes. A plain cedar hole gets enlarged, and the recycled-roof version with its predator guard is the answer to that for six dollars more.

The eighth of an inch that decides the tenant

The practical consequence is that 1-1/8 in is the sweet spot for most yards, and it is what both Kettle Moraine wren boxes use. You give up nothing a wren wants, you gain chickadees, and you stay below the size at which House Sparrows become a problem — which matters because House Sparrows are not protected and will evict or kill native cavity nesters in a box they can enter.

The published figures, side by side

Where to put it, and why wrens are forgiving

• 5 to 10 ft up, per NestWatch — lower than a bluebird box and well within reach of a stepladder, which makes cleaning realistic.
• Any orientation. NestWatch states this plainly for House Wren, which is unusual: most box species have a preferred facing.
• Within about 100 ft of woody vegetation, with enough clear space that the birds can fly straight to the hole.
• About 100 ft between boxes. House Wrens are territorial, so a cluster of boxes does not produce a cluster of pairs.
• Clean it out between seasons. All three boxes here open; that is what the hinge is for.

What not to buy

• A decorative birdhouse with no published hole size. It is the only figure that matters and its absence is the answer.
• Anything with a perch below the hole. Cavity nesters do not need one and it gives predators and House Sparrows somewhere to stand.
• A box that does not open. Old nest material has to come out, and a sealed box is an ornament with a hole in it.
• A 1-1/4 in hole, if House Sparrows are already a problem in your yard. That is the size at which they get in, and the 1-1/8 in boxes here are the specific answer.
