How to Do a Hive Split in Spring

A hive split is one of the best ways to increase your bee population without buying new packages. It’s also a natural way to manage swarming and keep your colonies healthy. If done in spring when brood is building up, you give both halves the best chance of becoming productive colonies.

Step 1: Confirm the Hive Is Strong Enough to Split

Before you split, your hive needs to be genuinely robust. Ideally, the colony should have filled at least two deep boxes (or three mediums) with bees and brood. If you’re unsure, do a quick frame count: pull out a few frames from the middle of the brood nest. You should see solid coverage of bees on both sides of at least 5–6 frames, plus capped brood and fresh eggs.

Timing matters. Late April through early June works well in many temperate parts of the Northern Hemisphere—early enough that the new colony has time to build up before winter, but late enough that you’re certain the hive is genuinely strong. If you’re in a different climate zone, the key principle is the same: split after the main nectar flow has begun and well before your local winter preparation period starts. Don’t split a hive that’s only been going for one season unless it’s exceptionally large; a first-year colony usually needs all its resources to survive winter.

Check the weather forecast too. You want a warm, calm day (ideally above 60°F) so bees can regulate their temperature in both boxes. If you split on a cold or rainy day, the separated bees may cluster too tightly and starve.

Step 2: Move Frames to the New Box

Set up your new box next to the original hive. You’ll split the brood and bees roughly in half.

Take four to five frames of brood (a mix of capped and uncapped) from the center of the original hive and move them into the new box. Include at least one frame with eggs or very young larvae—this is crucial for the queenless half. Place these frames in the center of the new box to keep them warm.

Then move two to three frames of honey and pollen from the edges of the original brood nest into the new box, positioning them on the outside of the brood frames. This gives the new colony immediate food without having to forage right away.

Fill the remaining space in the new box with empty drawn comb (comb that bees have already built out from the foundation, ready to use) if you have it, or with fresh foundation. The new colony needs room to expand, but not so much empty space that they can’t maintain cluster temperature.

Do the same for the original hive: it should now have four to five frames of brood, plus its remaining honey and pollen frames, with empty comb or foundation filling the rest.

Step 3: Ensure Each Half Has What It Needs

After you’ve moved frames, both boxes need to be self-sufficient. Each half should have brood, pollen, honey, and bees—but the most critical thing is bees. A frame of brood is worthless if no adult bees are there to incubate it.

Shake bees from the original hive into both boxes. Take a frame from the original hive that’s covered in bees, hold it over the new box, and give it a sharp shake. Repeat with a second frame. You want both boxes to have plenty of adult bees—aim for roughly equal coverage.

Check for food. Each box should have at least one frame with honey and pollen. If your hive was light on stores, add a frame of honey from a strong hive, or feed both halves with a 1:1 sugar-water solution in a feeder.

Now comes the critical decision: which half keeps the queen? The original hive (the one that stays in place) should keep the queen. This half will continue normally and recover quickly. The new box—moved at least two miles away (or use a screen/drift-reduction method if kept closer)—becomes the queenless half and will need a new queen.

Step 4: Requeening the Queenless Half

The queenless half has three options: let it raise its own queen, introduce a purchased queen, or give it a frame of eggs from the queened half.

Option 1: Let them raise a queen. Since you moved a frame with eggs or young larvae into the queenless box, the bees will likely build emergency queen cells. This is free and natural, but you won’t have a laying queen for 4–5 weeks (3 weeks to raise the queen, plus another week or two to mate and start laying). This delays the colony’s growth.

Option 2: Buy a queen. A mated queen starts laying within days of successful introduction. Wait 3–4 days after the split before introducing her—this gives the colony time to accept that they’re truly queenless. Introduce her in a queen cage with a candy plug; bees will chew through the candy over a few days and release her. Check after a week to confirm she’s laying.

Option 3: Give them a frame of eggs. After 3–4 days, move a frame of fresh eggs from the queened half into the queenless half. They’ll raise a queen from that frame, and you’ve avoided buying one. The downside is you’re slowing the original hive’s growth slightly.

Whichever route you choose, feed both halves if they’re light on stores. A queenless colony especially needs food while it’s raising a queen or waiting for a new one to arrive.
