Short version: face the entrance south to southeast so morning sun warms it early, mount it rigid at 3–5 feet (1–1.5 m) — roughly eye level — flush against a solid surface, and tuck it under a slight overhang for shelter from wind and driving rain. Put it within a short flight of flowering plants and near a patch of bare, damp soil, away from pesticide-treated ground. Get it up in late winter or very early spring, before mason bees emerge, and if you're past that window, leave it up anyway for summer leafcutter bees. That's the whole job. Here's why each part matters.
A quick note on who you're hosting: mason bees and leafcutter bees are solitary. There's no hive, no queen, and no honey — each female works alone, provisioning her own tunnels. They rarely sting, since they have no colony to defend. Placement is what determines whether they use the tunnels at all.
Aspect: Face South to Southeast
Orient the entrance so it catches morning sun — south to southeast is the target. Solitary bees need warmth to fly, and a habitat that stays in shade all morning simply gets used later, if at all. East-facing works if it's unobstructed early; west-facing tends to sit cold until afternoon, which shortens the bees' working day. Avoid full north exposure entirely — the tunnels rarely warm enough to be worth the trip.
Height: 3–5 Feet, at Eye Level
Mount it 3–5 feet (1–1.5 m) up — at or just above eye level. That height keeps the entrance clear of long grass and ground moisture, out of easy reach of curious pets, and still low enough that you can check on it or swap out tubes without a ladder. Much higher and you lose visibility into what's actually happening; much lower and the habitat competes with everything moving at ground level.
Mounting: Rigid, Never Swinging
Fix it flush against something solid — a fence post, a shed wall, a tree trunk — and skip anything that hangs from a wire or a hook. Movement deters nesting. A female bee assessing tunnels for a location to lay eggs treats a swaying structure as unstable, and she'll move on to somewhere still. A few screws into a solid surface will do more for occupancy than any other single change.
Shelter From Wind and Rain
Position the habitat out of the prevailing wind and away from driving rain, ideally under a slight overhang — an eave, a covered porch post, or a roofline. Wet tunnels are a problem for developing larvae, and constant wind at the entrance discourages bees from landing in the first place. Shelter and morning sun aren't in conflict; you're looking for a spot that gets warmed early and stays dry the rest of the time.
Proximity to Forage
Put the habitat within a short flight of flowering plants. Solitary bees forage over a much smaller range than honeybees, so a habitat set far from anything blooming asks more of them than it should. If your own garden is light on flowers, look at what's nearby over the fence — a short flight covers more ground than it sounds like.
A Source of Bare, Damp Soil Nearby
Mason bees seal each completed cell with mud, so they need access to bare, damp soil somewhere within reach — a border bed, an unmulched patch, even a shallow dish of soil kept slightly moist works. Leafcutter bees use plant material instead of mud, but the same nearby-forage logic applies to them: they need leaves to cut close by, not mud.
Skip Pesticide-Treated Areas
Keep the habitat and its surrounding forage away from areas treated with pesticides. This is straightforward, but it's the placement rule most often overlooked because the treated area and the habitat spot aren't always thought of as connected — a habitat next to a chemically treated lawn or bed puts every forage trip at risk.
Timing: When to Hang It
Get the habitat up in late winter or very early spring, ahead of mason bee emergence, so it's in place and weathered-in before the first bees are looking for tunnels. If you're reading this past that window, hang it anyway — mason bees emerge earlier in the season, but leafcutter bees are active through summer, so a mid-year placement still has a season ahead of it.
Spacing From Other Habitats
If you're also hosting a bat or owl habitat in the same yard, keep roughly 10–15 feet (3–4.5 m) between it and the bee habitat. That's enough separation to keep the two from interfering with each other's approach and activity without needing to think much further about layout.
Placement Checklist
- Entrance faces south to southeast for early morning sun
- Mounted at 3–5 feet (1–1.5 m), roughly eye level
- Fixed rigid against a solid surface — no wire, no swinging
- Sheltered from prevailing wind and driving rain, ideally under an overhang
- Within a short flight of flowering plants
- Bare, damp soil (or leaf-bearing plants for leafcutters) within reach
- Clear of pesticide-treated soil and plants
- Up by late winter/early spring, or anytime before summer for leafcutters
- At least 10–15 feet (3–4.5 m) from any bat or owl habitat
Once it's placed, the work shifts from where to when — how you maintain the habitat through the seasons is what keeps it usable year after year. It's also worth understanding how bees pollinate and what bees eat so you can judge whether your own garden is giving them enough reason to stay close. And if you want the broader case for why any of this is worth the wall space, why bees matter covers it in full.
If you're still deciding on a habitat to place, our bee house is built with these placement conditions in mind — species-specific tunnel sizing, a design meant to sit flush against a wall rather than dangle from it.
