Spring Apiary Inspection Guide – 20-Point Checklist

Complete spring beehive inspection guide with a 20-point checklist. Know what to look for, when to inspect, and how to record your findings.

---

A vibrant spring apiary in a flowering meadow — optimal timing and sunny weather are essential for the first inspection.

Spring is the most critical time in the beekeeping calendar. After months of winter cluster, your colonies have been through the most stressful period of the year. Some will have emerged strong and ready to build up. Others may have lost their queen, exhausted their stores, or succumbed to disease. You won't know which is which until you open the hives — and that's exactly what the spring inspection is for.

A thorough spring apiary inspection, done at the right time and in the right way, sets the foundation for the entire season. This guide covers everything: when to open the hives, what to look for, and how to record your findings efficiently.

When to Do Your Spring Inspection

Timing matters enormously. Opening hives too early can chill the brood and set colonies back significantly. Wait for the right conditions:

• Temperature: At least 57°F (14°C) in the shade, with no wind. Ideally 60-65°F (15-18°C). Below this threshold, brood temperature drops rapidly when frames are exposed to air.
• Time of day: Between 10am and 3pm, when foragers are out and the colony is at its least defensive.
• Weather: Sunny or partly cloudy. Avoid cloudy, windy, or rainy days — bees are more defensive in these conditions.
• Season cues: Hazel catkins, snowdrops, crocus, or early dandelions are blooming. Bees are making cleansing flights. These are your green lights to inspect.

💡 Pro tip: Don't try to do a full, deep inspection on every hive in one session early in spring. Do a quick "triage" first — check each colony for activity, stores, and obvious problems. Return for detailed inspections as temperatures rise.

Equipment You Need

Before heading to the apiary, make sure you have:

• Protective gear: Full suit with veil (or at minimum a veil and gloves). Spring colonies can be defensive after winter stress.
• Smoker: Loaded and lit. Use dry natural fuel — wood chips, pine needles, dried herbs, or cardboard. Have enough to last the whole inspection.
• Hive tool: A quality stainless steel hive tool is essential for breaking the propolis seal that builds up over winter — colonies glue everything shut.
• Bee brush: A soft bee brush helps gently move bees off frames when looking for the queen without crushing them.
• Queen marking kit: A queen marking pen and cage lets you mark your queen for easy spotting in future inspections. 2026 colour is yellow.
• Your hive records: What did you know about each colony going into winter? Use your Beekeeping Diary app or notes.

Methodical hive inspection: checking frame coverage, queen laying pattern, and colony stores.

The 20-Point Spring Inspection Checklist

Work through these points systematically for each hive. Split into five categories:

A — Colony Strength

• 1. Entrance activity: Before opening, watch the entrance for 2-3 minutes. Active foragers, pollen coming in, and orientation flights are all positive signs.
• 2. Frame coverage: Count how many frames are covered with bees. 3+ frames = viable colony. 1-2 frames = very weak, consider combining.
• 3. Population trend: Does the colony feel like it's building up, or declining? Are there lots of young (fuzzy) bees or mostly old, worn-looking ones?
• 4. Temperament: Note whether the colony is calm or defensive. Unusual aggression can indicate queenlessness or disease stress.

B — Queen Status

• 5. Find the queen: Look for her methodically, starting on frames with open brood. Is she marked from last year?
• 6. Laying pattern: Even if you don't see the queen, a tight, consistent laying pattern (mostly full frames of capped brood) indicates a healthy, productive queen.
• 7. Egg presence: Eggs are the most reliable sign of a recently active queen. Hold the frame up with the sun behind you and look for tiny rice-grain shapes standing upright in cells.
• 8. Queen age: Record when this queen was introduced. Queens over 3 years old should be evaluated for replacement.
• 9. Queen cells: Are there any queen cells? Emergency cells (on the face of comb) indicate the colony may have lost or superseded its queen. Swarm cells (on the bottom of frames) mean swarm preparation — note for follow-up.

C — Food Stores

• 10. Honey stores: How many frames of sealed honey are present? Spring minimum: at least 2 full frames. If stores are low, feed immediately.
• 11. Pollen stores: Fresh pollen coming in is great. Stored pollen (beebread) provides protein for brood rearing. If there's little pollen and the colony is trying to raise brood, consider pollen substitute.
• 12. Need for feeding: If total stores are less than 3-4 kg (roughly 2 full frames), supplement with 1:1 sugar syrup or candy board, depending on temperature.

Examining brood patterns and stores on active spring frames.

D — Disease and Pest Checks

• 13. Varroa mite count: Do an alcohol wash or sugar roll on 300 bees from a brood frame. Above 2-3% infestation requires treatment.
• 14. Deformed Wing Virus (DWV): Look for bees with crumpled, deformed wings near the entrance or on frames — a sign of high varroa levels.
• 15. American Foulbrood (AFB): Sunken, perforated cappings with dark brown, foul-smelling contents that stretch into a rope when probed with a matchstick. Notifiable disease — contact your apiary inspector immediately.
• 16. European Foulbrood (EFB): Twisted, discoloured larvae in uncapped cells. Sour smell. Less severe than AFB but still requires attention.
• 17. Chalkbrood: White or grey-black mummified larvae (look like chalk pieces) at the hive entrance or on the floor. Usually resolves as the colony strengthens, but note it.
• 18. Nosema: Brown streaks on the front of the hive and frames inside. Treat with good nutrition and ventilation; thymol-based treatments in severe cases.

E — Hive Condition

• 19. Floor and ventilation: Clean the floor of dead bees, debris, and mould. Ensure ventilation is adequate — poor ventilation contributes to disease.
• 20. Frames and comb condition: Dark, old frames (more than 5 years old) accumulate pathogens and pesticides. Plan to rotate out 2-3 old frames per hive this season, replacing with fresh foundation.

What to Do After the Inspection

Your checklist gives you a clear picture of each colony's status. Now act on it:

• Weak colony (fewer than 3 frames of bees): Consider uniting with another weak colony using the newspaper method. A colony too small to build up will struggle all season and is vulnerable to robbing and disease.
• Queenless colony: If no queen, no eggs, no young brood — add a frame with fresh eggs from a strong colony (the colony can raise an emergency queen) or introduce a mated queen.
• Low stores: Feed immediately. Starvation in spring is entirely preventable and can collapse a colony within days.
• Varroa above threshold: Treat now. See our detailed Varroa treatment guide.
• Disease symptoms: Contact your local bee inspector. Don't move equipment between hives until you know what you're dealing with.

Recording Your Inspection Data

Notes taken at the hive are infinitely more valuable than notes written from memory two days later. Record for each colony:

• Date and weather conditions
• Colony strength (frames of bees, frames of brood)
• Queen: seen / eggs present / marked / year introduced
• Food stores: frames of honey and pollen
• Disease and pest status
• Actions taken (feeding, treatment, frame rotation)
• Next action needed and when

Common Spring Inspection Mistakes

• Inspecting too early in cold weather: Chilling brood sets colonies back weeks and can cause larvae to die.
• Rushing through hives: Each hive deserves your full attention. Missing a disease sign or a queenless colony is a costly oversight.
• Over-smoking: Heavy smoke does not calm bees — it triggers a defensive response. Use light, cool smoke applied gently.
• Skipping record-keeping: "I'll remember" never works across multiple hives and multiple inspections.
• Not marking the queen: An unmarked queen is very hard to find in a populous summer colony. Mark her in spring when the colony is smaller.

Frequently Asked Questions

When should you start spring hive inspections?

Start spring inspections when temperatures consistently reach 15°C (60°F) or higher. In most temperate regions this is March to April.

How often should you inspect hives in spring?

Every 7-10 days during the active spring build-up period.

Should you feed hives in spring?

Yes, if food stores are low. Feed 1:1 sugar syrup to stimulate brood rearing.

How do you help a weak colony in spring?

Move a frame of young brood from a strong colony. Reduce the hive entrance. Feed generously. Requeen if the queen is failing.

What is the most important spring management task?

Feeding and varroa treatment are the two most critical in spring.

Conclusion

A well-executed spring inspection is the most valuable hour you'll spend in the apiary all year. It tells you the true state of your colonies, gives you a clear plan of action, and sets the stage for the season ahead.
