🐝 Bee Hotels: What Helps (and What Doesn’t)

Bee hotels are everywhere now — in garden centres, supermarkets, and social media posts. They’re often sold as an easy way to “save the bees”.

But good intentions don’t always help.

Some bee hotels can support wildlife. Others do very little — and some can even cause harm. Here’s what actually helps solitary bees in the UK, and what to be cautious about.

First: which bees use bee hotels?

In the UK, most bees do not live in hives. Around 70% of native bee species nest in the ground, while others use hollow plant stems, beetle burrows, or cracks in wood.

Bee hotels are mainly used by a small group of solitary bees, such as:

• Mason bees (Osmia species)
• Leafcutter bees (Megachile species)

They don’t help honeybees — and that’s okay. Solitary bees are excellent pollinators in their own right.

✅ What actually helps

1. The right tube sizes

Bee hotels work best when the nesting tubes are:

• 2–10 mm in diameter
• At least 10 cm deep
• Smooth inside (no splinters)

Shallow or rough holes make it harder for bees to nest successfully.

---

2. Natural, breathable materials

The most reliable options are:

• Bamboo canes
• Hollow plant stems (e.g. bramble, teasel)
• Untreated hardwood blocks with drilled holes

Avoid plastic tubes or painted interiors — they trap moisture and encourage mould.

---

3. Good placement

For UK conditions:

• Face south or south‑east
• Position 1–1.5 metres off the ground
• Angle slightly downwards so rain runs out
• Keep them sheltered from strong wind

A warm, dry spot matters more than size.

---

4. Maintenance (this part is often missed)

Bee hotels are not install‑and‑forget.

Without cleaning or replacement:

• Parasites build up
• Disease spreads between generations
• Mould can form inside tubes

A simple rule:

• Replace cardboard or paper tubes every year
• Replace bamboo or stems every 1–2 years
• Clean wooden blocks carefully in winter

⚠️ What to be cautious about

1. Decorative “insect hotels”

Large, mixed hotels filled with pinecones, bricks, straw, and tubes are popular — but often poorly designed.

They may:

• Attract pests
• Trap moisture
• Provide unsuitable nesting spaces

They look good, but they’re not always helpful.

---

2. Very large bee hotels

Bigger isn’t better. Large hotels can increase parasite spread and attract predators.

Several small, well‑placed hotels are better than one huge one.

---

3. Thinking hotels are enough

Bee hotels only help a small number of species.

The single most helpful thing you can do is still:

• Leave some bare ground
• Let plants flower
• Reduce mowing and tidying

---

What helps bees more than any hotel

If you only do one thing, do this:

• Let dandelions, clover, and “weeds” flower
• Leave stems standing over winter
• Avoid pesticides
• Plant a mix of native and pollinator‑friendly plants

Bee hotels are a bonus, not a solution.

A gentler way forward

You don’t need a perfect garden — or a perfect bee hotel — to help.

Doing less, leaving space, and letting nature be messy often helps far more than buying something new.
