The Complete Spring Inspection Checklist

Spring is a pivotal moment in every beekeeper's year. After months of waiting through winter, the first warm days bring both excitement and responsibility. A thorough spring inspection sets the tone for the entire season ahead—get it right, and your colonies will reward you with vigorous growth and abundant harvests.

When to Inspect

Timing matters. Wait for a day when temperatures reach at least 15°C (59°F) with calm winds and sunshine. Inspecting too early risks chilling the brood, while waiting too long could mean missing signs of trouble. In most temperate climates, late February to mid-March is the sweet spot, but always let the weather—not the calendar—be your guide.

Step 1: External Observation

Before cracking the hive open, spend a few minutes watching. Are bees flying in and out with purpose? Do you see pollen being carried in? A healthy colony will show steady traffic on warm days. Look for dead bees near the entrance—a small number is normal after winter, but piles could signal disease or starvation.

Step 2: Check Food Stores

This is your most critical assessment. Lift the hive from behind to gauge weight. A dangerously light hive needs emergency feeding immediately. Once inside, look for capped honey frames—ideally, colonies should still have 3-5 frames of stores at this point. If stores are low, provide 1:1 sugar syrup to bridge the gap until nectar flows begin.

Step 3: Assess the Queen

You don't necessarily need to see the queen herself. Look for fresh eggs—tiny white rods standing upright in the bottom of cells. Eggs mean the queen was active within the last three days. A solid brood pattern with few empty cells indicates a healthy, productive queen. Scattered or patchy brood is a red flag that warrants closer investigation.

Step 4: Brood Health

Examine the brood carefully. Healthy capped brood should be tan to brown with slightly convex cappings. Watch for:

• Sunken or perforated cappings – possible sign of American Foulbrood
• Discolored larvae – could indicate European Foulbrood or other diseases
• Chalky white or black mummies – signs of Chalkbrood
• Shotgun pattern – scattered brood could mean disease, poor queen, or inbreeding

If anything looks off, take photos and consult your local bee inspector.

Step 5: Varroa Assessment

Even in early spring, it's important to get a baseline varroa count. An alcohol wash or sugar roll of approximately 300 bees (half a cup) from a brood frame gives you an accurate mite percentage. Counts above 2% in spring warrant early treatment consideration, as mite populations will grow exponentially with the colony.

Step 6: Space Management

Spring buildup can be explosive. If the colony already occupies 7-8 frames, consider adding a super or second brood box. Crowding is the primary trigger for swarming, and once bees have made up their minds to swarm, it's very difficult to stop them. Stay ahead of the curve.

Step 7: Clean and Repair

Replace any frames with excessive dark comb (more than 3 years old), damaged frames, or excessive propolis buildup. Spring is also the time to clean bottom boards of winter debris, check for mouse damage, and ensure ventilation is adequate.

Recording Your Findings

Perhaps the most important step: write everything down. Perhaps the most important step: write everything down. Use a hive management app like ApiaryPilot to log queen status, brood pattern scores, food levels, varroa counts, and any actions taken. Your future self will thank you when patterns emerge across inspections and seasons. queen status, brood pattern scores, food levels, varroa counts, and any actions taken.

Spring inspections aren't just about ticking boxes—they're about forming a relationship with each colony and understanding its unique character. Take your time, be gentle, and let the bees teach you.
