To install a nuc, you set the nuc box on the spot where the full hive will stand, let the bees settle, then lift its five frames out one at a time and place them in the same order and orientation into the center of a ten-frame brood box, fill the remaining space with frames of foundation, shake the stragglers in, push the frames together, and close up with a feeder and an entrance reducer. Because a nuc already has a laying queen, brood, drawn comb and food, it is the most forgiving way to start a colony — this guide covers when to do it, how to transport the box, the transfer itself, and what to check in the first two weeks.
Key Takeaways
- A standard nuc is five deep frames: two or three of brood in all stages, two of honey and pollen, a laying queen the bees already know, and roughly 10,000–15,000 workers.
- Set the nuc where the hive will stand and let it sit before transferring — 15 minutes at minimum, or the five-day method Alabama Cooperative Extension recommends for beginners.
- Move the frames in the same order and facing the same way, into the middle of the box, and never leave a gap: the brood nest stays intact and the queen stays safe.
- Late afternoon or early evening is the most-recommended time; a warm, calm day above about 60°F is the real requirement, and never open frames after dark.
- Feed 1:1 syrup with an in-hive feeder until the colony has drawn most of the box, check for eggs at day 7–10, and add a second box once seven or eight frames are covered.

What a Nuc Is and What Comes Inside
“Nuc” is short for nucleus colony, and the University of Florida’s beekeeping extension publication defines it precisely:
“The term ‘nuc,’ a shortened version of the term ‘nucleus colony,’ most correctly refers to a small-sized hive in which a small colony of bees resides but also can be used to describe the small colony of bees itself.”
In practice a purchased nuc is a five-frame box of deep frames. Alabama Cooperative Extension describes the standard contents as “five frames with a drawn-out comb, a laying queen, two frames of food stores, and two to three frames of brood,” and suppliers such as Foxhound Bee Company put the population at roughly 10,000 to 15,000 bees including the queen. Everything a package of bees has to build from nothing — comb, brood, stores, a queen the workers have accepted — is already there, which is why a nuc typically outpaces a package installed on the same day by several weeks. It costs more and is usually picked up locally rather than shipped; our guide to buying packaged bees and nucs in the USA covers sourcing, and how to install package bees covers the other route.
| Factor | Nuc | Package |
|---|---|---|
| What you get | 5 drawn frames with brood, stores, workers and a laying queen | Loose bees in a screened box, caged queen, no comb |
| Queen status | Already accepted and laying | Must be accepted over 1–3 days; occasional rejection |
| Time to fill a deep box | Often 3–5 weeks in a good spring | Often 6–8 weeks or more |
| Installation | Move five frames in order | Shake bees in, hang the cage |
| Typical price (2026, US) | Higher; local pickup | Lower; shippable |
| Disease risk | Comes with comb — inspect frames before you buy | No comb, so lower risk of comb-borne disease |

When to Install a Nuc: Season, Weather and Time of Day
Nucs are a spring product. Producers in the South start pickups in March — Alabama Extension’s guide says to “request nuc pickup from mid-March through early May” — and the window slides later as you go north, with May and early June typical in the northern states. The earlier you install, the longer the colony has to build before the main flow, so book in winter; nucs sell out. Our guide on the best time of year to start beekeeping maps the pickup season to the flow by region.
Weather matters more than the calendar on the day itself. Opening a nuc means exposing brood, so wait for a calm, dry day above roughly 60°F; a cold, windy afternoon chills brood and makes the bees defensive. On time of day, most suppliers and extension guides converge on late afternoon or early evening:
“The late afternoon or early evening is the recommended time to install a nucleus hive, also known as a nuc hive. This timing allows the bees to settle into their new hive before nightfall and start exploring the following morning when the weather is typically favorable.”
A warm, sunny midday also works well if the nuc has already been sitting in position, because most foragers are out and fewer bees are in the box to manage. The one time to avoid is after dark: bees cannot orient by sight, they crawl rather than fly, and a colony opened at night is far more defensive than the same colony an hour before sunset. If you pick the nuc up in the morning, set it in place and give it at least an hour — or the rest of the day — before you open it.
| Condition | Install? | Notes |
|---|---|---|
| Calm, dry, above 60°F, late afternoon | Yes — ideal | Bees settle overnight and orient in the morning |
| Warm sunny midday, nuc already in position | Yes | Fewer bees in the box; work steadily |
| Cool (50–60°F) or breezy | Wait if you can | Leave the nuc closed-up-in-place with its entrance open; it can wait days |
| Rain | Wait | Wet, chilled brood and angry bees |
| After dark | No | Bees can’t fly or orient; defensive behavior spikes |
Picking Up and Transporting a Nuc
Ask to see the frames before you pay if the seller allows it: you want a queen or at least eggs, a solid brood pattern, and no signs of disease — our checklist for inspecting purchased nucs for disease risk covers what to look for. For the drive home, close the entrance with the seller’s mesh or a strip of foam, strap the box so it cannot slide, keep it upright and level, and keep the cabin cool — a five-frame box of bees in a closed car in the sun can overheat in well under an hour, and heat is the main way nucs die in transit. Don’t put a closed wooden nuc in a sealed trunk; it needs airflow through its ventilation screen. Keep the trip as short as practical and unload the moment you arrive. Meyer Bees publishes sensible nuc transport guidelines for their customers, and our review of the best nuc boxes for transporting bees covers ventilated boxes if you will be moving nucs more than once.
Equipment You Need
| Category | Item | Why |
|---|---|---|
| Hive | Bottom board, one deep brood box, inner and outer cover, hive stand | The nuc’s five deep frames go into a deep box — medium frames don’t fit |
| Hive | Five frames of foundation or drawn comb | To fill the box beside the nuc frames; never leave empty space |
| Hive | Entrance reducer | A small colony can’t defend a full entrance |
| Feeding | In-hive or top feeder and a gallon of 1:1 syrup | Drawing the other five frames takes energy |
| Tools | Hive tool, smoker with fuel, bee brush | Frames in a nuc are often glued down with propolis |
| Tools | Ratchet strap and entrance mesh or foam | For the drive home |
| Protection | Veil, gloves, jacket or suit | A nuc is a real colony with brood to defend |

Preparing the Hive and the Site
Have the hive assembled, painted and standing on a level stand before pickup day, on the exact spot where it will stay — the bees will orient to that entrance and moving the hive later means losing foragers. Morning sun, some afternoon shade in hot regions, a windbreak and a nearby water source are the basics; our apiary setup guide and climate-based hive placement cover regional details. Take five frames out of the deep box so there is an empty center to receive the nuc frames, fit the entrance reducer, and have the feeder filled and the covers within reach. If the nuc will sit next to other colonies, stagger the entrances or face them slightly differently; new nucs placed in a straight row drift into each other badly (How to Prevent Drifting Between Hives: Best Practices). If the nuc is joining an existing apiary, read how to quarantine new bees first.
Same-Day Transfer or Five Days in Place
There are two respectable schools on how long the nuc should sit before you move the frames. Suppliers generally transfer the same day: Foxhound’s guide has you set the nuc in place “for at least 15 minutes before transferring the frames,” long enough for the bees to calm after the drive. Alabama Cooperative Extension’s beginner guide takes the patient route:
“Place newly purchased nuc in the apiary directly beside the hive in which you plan to install them. … Leave the nuc in place for 5 days to let the colony get accustomed to their new location.”
Both work. The five-day method lets the foragers learn the location and lets you pick a perfect-weather day for the transfer, at the cost of the colony spending nearly a week cramped in five frames during peak build-up; the same-day method gets the queen laying into fresh space immediately but asks you to work a colony that has just been driven across the county. For a first nuc, sitting the box in place overnight and transferring the next afternoon is a sensible middle path. Whichever you choose, open the nuc’s entrance as soon as it is in position so foragers can fly.
How to Install a Nuc Step by Step
Step 1: Set the nuc in position and let it settle
Put the nuc box directly beside, or on top of, the empty hive it will go into, with its entrance facing the same direction as the hive’s entrance. Open the entrance and wait — 15 minutes at the very least, an hour or a day if you can.
Step 2: Light the smoker and open the box
A couple of cool puffs at the entrance and under the lid are plenty; nucs are usually gentle. Pry the lid off and use the hive tool to break the propolis seal on the outermost frame before you lift anything — nuc frames are packed tight and glued down, and yanking a stuck frame rolls bees and can kill the queen.
Step 3: Move the frames in order, one at a time
Lift the first outer frame straight up, look at both sides, and place it in the center of the deep box. Take the next frame and set it beside the first, keeping the same order and the same face pointing the same way — Alabama Extension’s wording is “keeping them in order and facing the same direction.” The brood frames stay together in the middle with the food frames on the outside, exactly as the bees arranged them. Note where you see the queen; if you spot her, that frame goes into the box especially gently.
Step 4: Read the brood as you go
This is your one chance to look at every frame without stress. You want eggs (proof the queen was laying within the last three days), larvae, and capped worker brood in a solid pattern with few empty cells. Spotty brood, a lot of drone brood or sunken, perforated cappings are reasons to phone the seller now, not in a month; our disease-inspection guide shows what each of these looks like.
Step 5: Fill the box and shake in the stragglers
Slide the five frames of foundation in beside the nuc frames — two on one side and three on the other, as Alabama Extension suggests, or split however the brood nest sits best — so the box is completely full. Push all ten frames together toward the center with the hive tool; any slack belongs between the outer frames and the box wall, not in the brood nest. Then turn the empty nuc box upside down over the frames and give it a sharp shake to drop the remaining bees in, or set it open on the ground in front of the entrance and let them walk home over the evening.
Step 6: Feeder, reducer, covers
Put the feeder in place, set the entrance reducer to its smaller opening, fit the inner and outer covers, and step away. Leave the empty nuc box at the entrance until dark and remove it once the last bees have left, so returning foragers don’t keep landing on it.
| Step | Action | Key point |
|---|---|---|
| 1 | Nuc in position, entrance open, let it settle | Same spot and facing as the final hive |
| 2 | Light smoke; break propolis seals before lifting | Don’t roll bees on a stuck frame |
| 3 | Frames into the center of the deep, same order and facing | Brood nest stays intact |
| 4 | Check each frame for eggs, larvae, capped brood | Call the seller today if something is wrong |
| 5 | Fill with foundation, push frames together, shake stragglers in | No gaps anywhere in the box |
| 6 | Feeder on, reducer in, covers on | Then leave the colony alone for a week |
Feeding After Installation
A nuc arrives with two frames of stores, but it also arrives with five frames of foundation to draw and a queen that wants to lay into them, so feed 1:1 sugar syrup from day one unless a strong nectar flow is on. Foxhound’s rule of thumb is to keep feeding until the colony has the equivalent of about ten medium frames of stores; a simpler target is to feed until seven or eight of the ten deep frames are drawn and covered with bees, then add the second box (when to add a second box to a nuc). Use an in-hive or top feeder rather than an entrance feeder — a small colony fed at the front door invites robbing, and feeding bees without causing robbing explains the alternatives. A pollen patty is only needed in a cold, wet spring when the bees can’t forage; in most springs the nuc’s foragers will bring in more pollen than the brood can use.
The First Two Weeks
Resist opening the hive for the first week. Watch the entrance instead: orientation flights the first afternoon, pollen coming in by day two or three, and a steady drop in syrup are all the confirmation you need. Then do one proper inspection at day 7–10, looking for eggs and young larvae on the new comb — proof the queen survived the move and is laying into the space you gave her. Our guide to the first inspection after installing a nuc walks through it frame by frame, and why a new nuc has no eggs covers the (usually benign) reasons you might not find any yet.
| When | What to do | What you’re looking for |
|---|---|---|
| Day 1 | Watch the entrance; remove the empty nuc box at dusk | Orientation flights, calm traffic |
| Day 2–6 | Top up the feeder without pulling frames | Pollen coming in; syrup being taken |
| Day 7–10 | First full inspection | Eggs and larvae on newly drawn comb; solid brood pattern |
| Day 14–21 | Second inspection; straighten any cross comb | Comb drawn on 6–8 frames; no queen cells along the bottom bars |
| Week 3–6 | Add the second box at 7–8 frames covered | Steady growth; open the entrance reducer as traffic builds |
Nucs grow fast, and a strong one installed in April can be crowded and thinking about swarming by June. Queen cells along the bottoms of frames in a colony that has filled its box are the signal to add space immediately — or, in a good year, to make an increase (can you split a first-year nuc?). From there the colony follows the ordinary calendar in our spring beekeeping checklist.
Troubleshooting
| Problem | What it usually means | What to do |
|---|---|---|
| Can’t find the queen during the transfer | She’s there but hiding — normal | Eggs are the proof; don’t keep hunting, close up |
| No eggs or larvae at day 7–10 | Queen lost in the move, or a poor queen | Recheck in 3 days; if still none and no queen cells, requeen or call the seller |
| Queen cells on the frames at installation | Nuc was crowded, or the seller’s queen failed | Ask the seller; if the queen is present and laying, remove the cells and give space |
| Bees clustered on the empty nuc box at night | Queen or her scent is still in the box | Check the box for the queen; shake the bees into the hive |
| Fighting at the entrance, syrup-smeared bees | Robbing | Reduce the entrance to one bee width; feed inside only |
| Heavy traffic into a neighboring hive | Drifting between adjacent colonies | Turn entrances to face different directions; add landmarks |
| Comb built in the frame gap or across frames | Frames not pushed together | Straighten within a day or two; fill every gap |
| Colony left the hive in the first days | Absconding — rare in nucs with brood | Check for a queen excluder-under-the-brood-box trick next time; usually a sign the brood was chilled or the box overheated |
Nuc problems are rarer than package problems for one reason: the brood. Bees very seldom abandon open brood, which is why a nuc that is chilled, jostled and fed late usually still settles down and thrives. If the seller’s queen turns out to be poor, though, requeen early rather than hoping; a first-year colony has no time to waste.

FAQ
What is the best time of day to install a nuc?
Late afternoon or early evening, so the bees settle into the new hive before dark and orient the next morning. A warm, sunny midday also works if the nuc has been sitting in position. Never open the frames after dark — the bees can’t fly or orient and become very defensive.
Can you install a nuc at sunset?
Yes, as long as there is enough light to see eggs and work carefully — the last hour before sunset is one of the most-recommended windows. Once it is actually dark, wait for the next day.
How long should a nuc sit before I transfer the frames?
At least 15 minutes after the drive, and ideally overnight. Alabama Cooperative Extension recommends beginners leave the nuc in place for five days before transferring; either approach works if the nuc’s entrance is open so the bees can fly.
Do I need to feed a nuc after installing it?
Yes, unless a strong nectar flow is on. Feed 1:1 sugar syrup in an in-hive or top feeder until seven or eight of the ten frames are drawn, then add the second box and stop feeding once the bees ignore the feeder.
How soon should I inspect a newly installed nuc?
Leave it closed for about a week, then do one inspection at day 7–10 looking for eggs and larvae on the new comb. Entrance activity and syrup consumption tell you what you need to know in between.
What if I can’t find the queen when I install the nuc?
That’s normal — a nuc has thousands of bees on five frames. Eggs standing upright in the cells are proof she was laying within the last three days; if you see eggs, close up and don’t keep searching.
Is a nuc better than a package for a first hive?
For most beginners, yes: the queen is already accepted and laying, there is brood and drawn comb, and the colony builds up several weeks faster. The trade-offs are a higher price, local pickup instead of shipping, and the need to inspect the comb for disease before you buy.
