What to Look for in a Hive Inspection

An inspection is a look at what's actually going on inside the hive, checked against a rough order rather than done at random. This page walks through that order and what each part is for; the inspection log is where you'd record what you find and keep it over time.

What to bring

A veterinary hive inspection protocol written for Massachusetts's state program lists what it expects an inspector to have on hand before opening a hive: "Including: Apiary inspection form, veil, hive tool, smoker, diagnostic guide, sanitizing materials (rubbing alcohol, steel wool), disease sampling materials (Q tips, paper bags), and an alcohol wash kit (jar with mesh lid, rubbing alcohol, half-cup measure, dish pan)." A hobbyist's own kit will be smaller, but the shape of it is the same: something to see with, something to open the hive with, something to calm the bees with, and something to sample mites with if you're checking them at the same visit.

Entrance, then inside

The first read on a colony happens before the hive is even open, watching how busy the entrance is and whether that looks like a colony coming or going normally for the season. Once it's open, the order generally runs from the outside frames in: look for the queen or, more reliably, for eggs, which tell you she was there within the last few days even if you don't spot her. Check the brood pattern next — whether capped and uncapped brood fill a solid area of comb or are scattered thin and patchy, since a scattered pattern is one of the first things that reads as off before you've identified why. Then check stores: how much nectar or honey and how much pollen are in the frames above the brood, and how many frames the bees actually cover, since coverage is a rough stand-in for colony strength at that point in the season.

Swarm signs

Spring inspections add a specific thing to look for. Utah State's own calendar explains why: "May marks the beginning of swarm season due to rapidly expanding bee populations." A colony that's outgrowing its space starts building queen cells to raise a new queen before part of the colony leaves with the old one, and checking for that is a routine part of a spring inspection: "Management practices such as adding additional boxes, splitting the hive, and watching for the appearance of new queen cells near the bottom of the frames, can help reduce the chance of swarming."

Symptoms are not a diagnosis

The last thing an inspection checks is whether anything in the brood or on the bees looks like disease or a pest. What a symptom checklist can honestly do is record what you saw — a discoloration, an odor, an unusual larval shape — not tell you which disease caused it. NC State's own extension guidance keeps that distinction explicit even where it names a specific concern: "If you suspect a tracheal-mite infestation, contact your regional NCDA&CS Apiary inspector." Its general advice for spotting trouble early is the same idea in a different form: "Maintain strong colonies and inspect weak colonies often." A weak colony is where symptoms show up first, and inspecting it more often catches a developing problem sooner than a full-apiary inspection on a fixed schedule would.

Even a state's own official inspection protocol doesn't diagnose brood disease in the field. UMass's protocol has the inspector collect a sample instead: "If you suspect brood disease, obtain a brood sample using a Q-tip or toothpick, and place it a paper bag." From there the case goes up, not down: "Contact the MDAR Apiary team to alert them of the potential diagnosis." If a trained inspector working from a written protocol routes a suspected disease to a lab and a state agency rather than calling it on sight, a hobbyist noticing the same symptom should do the same thing: note what was seen, and contact your own state apiary inspector, findable through the Apiary Inspectors of America directory, rather than treat for a disease that was never confirmed.

Recording it

None of this is worth much if it isn't compared against last month's inspection. The inspection log saves each visit's entrance, queen, brood, stores, frame count, swarm and disease notes, and mite count in your browser, by hive, so a change from one visit to the next stands out on its own rather than depending on memory.
