Inspecting Your Hives

By: Richard Wahl

Growing up as a kid on the same farm property I now own, I can still picture the half-dozen beehives that once sat quietly down a lane across the road. They belonged to a local beekeeper my grandfather had given permission to keep on his property. As kids my brothers, sister and I were given one simple instruction. “Stay away from the beehives unless you want to get stung.” Aside from that warning, and the occasional jar or two of honey the beekeeper dropped off each Fall; that was the full extent of my early exposure to honey bees. Those childhood precautions stuck with me as many years later I prepared for my very first full hive inspection. While contemplating going through the colony of live bees frame by frame, I felt a healthy dose of trepidation. It is perfectly normal to have that first hive inspection make even the calmest beginner feel a bit jittery. You are about to open a box buzzing with thousands of insects you have been taught since childhood to avoid, so your nerves are not a sign of weakness, they are a sign you understand the responsibility. The good news is that honey bees are far more interested in tending their brood and gathering nectar than picking a fight. With a little preparation, steady movements, and a calm mindset, that anxious energy can quickly turn into confident curiosity. As my own confidence increased with each subsequent hive inspection, I found the bees more naturally just going about their business of collecting nectar and pollen and ignoring my presence. There seemed to be greater acceptance of my presence with fewer bees attacking my veil as I became more relaxed pursuing later inspections. It was almost as if the bees began to realize I was there to assist rather than being an intruder to their detriment.

Preparations Before the First Inspection
Before you ever lift the outer cover a good hive inspection starts with preparation outside of the hive. This is the time to decide the purpose for your inspection. Are you simply checking health and stores, or are you prepared to make a split if you find swarm cells or congestion? Having a plan, and your gear ready ahead of time, keeps you calm and keeps the hive open for the shortest time possible.

If the colony is found to be booming, anticipate the need for replacement frames and even a spare super. If the colony is in one brood deep there may be a need to add a second brood super or possibly that first honey super or two. Since the first inspection normally occurs at the beginning of a nectar flow, the number of bees in the hive can increase at a dramatic pace if there is open comb or new frames to be drawn, which gives the queen more space to lay eggs. In SE Michigan it is not unusual to remove several older pollen or honey filled frames to be replaced by new frames. Having frames and supers on hand saves the time and effort of traveling back to the storage area to retrieve equipment once the hive is opened. I make it a habit to set any inspection tools, smoker or items that may need to be added to colonies, near the hives before I ever put the protective bee suit on.

Weather Considerations
Weather plays a bigger role in a full hive inspection than many new beekeepers realize. Ideally, choose a warm, dry, calm day when temperatures are at least in the mid-50s°F (about 10°C) or higher, because that’s when most field bees are out foraging and the colony population inside the hive is reduced. With fewer bees inside, it means less congestion on the frames and less defensive behavior. Avoid inspections during rain, high humidity, or strong winds, since bees become irritable when they cannot fly well. Midday or early afternoon sunlight also matters and is usually the best time for inspections because temperatures have stabilized and nectar flow is often underway, which keeps bees occupied and calmer. Early morning or late evening inspections tend to encounter more bees at home and a more defensive colony. This is where many beginners who have full time jobs run into trouble. If the only available time to do inspections is early before travel to work, or late in the day after arriving home to collect tools and then go to the bee yard, it may not be an opportune time as far as the bees are concerned. I once mentored a new beekeeper with a busy work schedule that only had the opportunity to visit their hives on weekends. One Summer it seemed every weekend had rainy, windy or colder days which were not opportune times for inspections. I am sure there were key problem clues in some of that beekeeper’s hives that could have been caught sooner if mid-week inspections would have occurred during better weather. If a cold front, storm system, or sudden temperature drop is approaching, it is wise to postpone a full inspection and instead perform only a quick external check. Planning around weather is not just about beekeeper comfort, it is about minimizing stress on the colony and ensuring you can observe the hive at its most natural, productive state.

Prior Workspace Staging and Smoker Use
Equally important is the staging of your workspace. Place your hive tool where you can grab it without fumbling, position an empty super or frame rest to hold frames safely, and clear the ground around the hive so you are not tripping while holding frames covered in bees. If you use a notebook or app for records, have it open and ready. Small external preparations may seem minor, but they set the tone for the whole inspection. When you are organized before opening the hive, you move with purpose instead of hesitation, and the bees will notice the difference.

Lighting and using a smoker properly can make the difference between a smooth inspection and a defensive colony. Light your smoker first and make sure it is producing cool, steady smoke. Start with dry, easily ignitable fuel such as paper, pine needles, burlap, or wood shavings. Light this fuel in the bottom until a steady flame is established before packing additional fuel on top. The goal is cool, dense smoke, not hot sparks. Test the smoke on your hand; it should feel cool. Apply a few gentle puffs at the entrance and under the lid and then wait about thirty seconds before opening. Smoke works by masking alarm pheromones and encouraging bees to gorge on honey, which makes them calmer. Use it sparingly as too much smoke agitates the bees. Throughout the inspection, add a light puff only when bees become defensive or begin to rise in agitation.

Before Lifting the Outer Cover
Simply watching activity at the entrance can reveal a surprising amount about colony condition without lifting the lid. The steady traffic of foragers bringing in pollen loads usually signals a healthy colony with brood to feed and a laying queen, while bees returning with enlarged abdomens may be bringing in nectar or water. Fanning bees can indicate ventilation activity, temperature regulation, honey curing, or pheromone signaling, while guard bees posted at the entrance show a normal defensive behavior. You may on occasion see a guard bee fly up to meet an arrival just to check they belong to the hive and are not a threat. Other visible signs that indicate a normally functioning colony may include orientation flights of young bees continuously circling at the hive front, undertaker bees removing dead bodies, or bees taking cleansing flights on those warmer Winter days. These are all clues about population dynamics, seasonal shifts, and internal hive health being in an acceptable normal range. Conversely, unusually low activity, excessive defensiveness, or erratic fighting at the entrance can signal problems ranging from queen issues to robbing pressure. That being said, entrance observation should complement hands-on inspections, while providing ample clues to what may be going on inside. External signs can lag behind internal problems by weeks, and while watching flight patterns helps a beekeeper develop intuition and reduce unnecessary disturbances, periodic frame-by-frame inspections remain essential for confirming brood patterns, food stores, and disease status. Used together, outside observation and interior inspection form a balanced approach. I will always do a thorough frame-by-frame inspection about the time of the first mass dandelions blossoming in the late Spring. In my area this has occurred at the very end of April or early May each year.

Removing the First Frame
The first frame you chose to remove sets the tone for the entire inspection. It is normal to start with an outermost frame or the one second in rather than pulling a frame from the center. Use a hive tool to gently loosen the frame as you pry against an adjoining frame just enough to break the propolis seal without jerking or twisting. Prying against a frame and not against the hive super minimizes any potential damage to the box. If a frame is damaged it is much easier to replace than the wall of a damaged super. Additionally, edge frames typically contain fewer bees and less brood, giving you space to work and reducing the chance of rolling or injuring bees as you maneuver. It is also likely the queen is not on one of the outermost frames reducing the chance of rolling her when removing the frame. Once loosened, grasp the top bar firmly at both ends and lift straight up in a slow, steady motion. Keeping the frame vertical prevents comb damage and minimizes nectar or honey dripping if it is a honey frame.

After removing that first frame, set it aside in a frame holder or lean it carefully against the hive body in the shade. That open space becomes your working slot for sliding subsequent frames sideways before lifting them out. Move each frame slowly; watching for the queen and keeping bees clear of pinch points. Inspect each frame in sequence; look for brood patterns, food stores, pest signs, and comb condition, then return the frame to its original spot, sliding it to the open position, before moving to the next. Working methodically from one side to the other keeps the colony organized, reduces bee agitation, and ensures you do not accidentally skip important frames during the inspection. After viewing all frames, slide them back into their original position and replace that first removed frame.

Queen Management and Things to Watch For
During frame-by-frame hive inspections, each comb should be read like a page in the colony’s story, with attention paid to both bee behavior and brood patterns. Look first for eggs and very young larvae to confirm a laying queen is present and then evaluate brood consistency. A solid, tight pattern usually signals a healthy colony, while scattered or spotty brood may hint at queen issues, disease, or pest stress. You do not actually have to see the queen; if you see fresh eggs that is her signature indicating her presence. Queens are usually found on frames containing eggs or very young larvae rather than capped brood or honey frames. Inspections are the perfect time to address queen management. If you spot the queen and she is unmarked, consider marking her while the frame is already out and under your control. A small dot of paint can save countless minutes in future inspections and helps track her age and lineage. While handling her, note her size, mobility, and the attention she receives from surrounding workers, all of which reflect colony confidence in her performance.

Check capped brood too, keeping an eye out for sunken or perforated cappings that might signal brood disease, and scan frame edges and corners for mites, beetles, or wax moth activity. Note food stores and whether nectar, pollen, and honey reserves match colony size and the season. Spring inspections lean toward brood expansion and space needs, while Fall inspections focus more on stores and Winter readiness. If you are working in cool weather, keep frame exposure short and deliberate so brood does not chill while you inspect it. Finally, observe the bees themselves; their temperament, movement, and sound often reveal as much as the comb does, giving you a full picture of colony health before you return each frame to its original position.

Carefully noting egg, larva and brood patterns will determine how soon follow up inspections should occur. If there are mostly eggs and young larva on three or more frames you may have another fourteen to seventeen days before becoming concerned as it takes 21 days from egg to emerging worker bee. If four or more frames are covered in capped pupa which will emerge at any time in the next one to eleven days, with bees working on all frames, it may be time to add more brood frames and or a honey super or two. The general rule of thumb is to add supers when 80% or more of the frames are being used by the bees for brood, pollen or nectar storage. Timing is critical; it is better to add space early than late to prevent swarming, which can occur if the hive becomes congested. This is where good note taking can assist in deciding follow up inspection times. Any partially or fully drawn wax comb from the previous seasons that has been emptied by the bees and that can be replaced in a hive is a real asset.

It is estimated that bees need to eat from eight to ten pounds of honey to produce one pound of wax.

Feeding and Mite Checks
Building on those observations, a thorough inspection is also the beekeeper’s opportunity to act, not just to observe. If food stores appear light for the colony’s size or for the season ahead, supplemental feeding may be warranted to maintain brood rearing and prevent stress that can weaken the hive. In the early Spring one to one sugar syrup by volume, once temperatures routinely reach 50°F (10°C) each day, can aid colony development. Naturally, any external feeding should cease once honey supers are in place to take advantage of any nectar flow. We do not want to take honey that is made out of our supplemental sugar syrup. In the Fall, after the last honey supers are removed, two parts sugar to one part water syrup is appropriate to help build up those Winter bees. Feeding should support colony goals, not replace natural foraging unless conditions demand it.

This is also an ideal time to conduct mite testing, since visual checks alone rarely reveal the true parasite load. An alcohol wash or sugar roll using a half cup of bees (approx. 300 bees) from brood frames provides reliable numbers to guide treatment decisions, helping you stay ahead of infestations rather than reacting after damage is done. As a rule of thumb, treatment is recommended when mite levels are 1% (3-4 mites) or more in the Spring, 2% (6-9 mites) or more in Summer, and 3% (9-12 mites) or more in the Fall. By pairing careful observation with timely action, feeding when needed, testing for mites, and maintaining clear queen identification, you transform a routine inspection into purposeful stewardship, ensuring each visit leaves the colony in a better position to thrive.

To Summarize
Used together, outside observation and interior inspection create a balanced, thoughtful approach to hive management. While one minimizes disruption the other confirms what the bees’ front-door behavior is trying to tell you. When you first lift the lid and glimpse that organized, purposeful world inside, the nerves tend to fade. That shift, from apprehension to fascination, is where real beekeeping begins. Effective hive inspections are among the most important skills a beekeeper can develop because every management decision, from swarm prevention to disease control, depends on what you observe within the colony. Good inspections are calm, methodical, and purposeful, not rushed or overly intrusive. They begin before the hive is opened, with proper timing, preparation, and seasonal awareness. Choosing a warm, calm day, having tools ready, and understanding whether the colony’s priority is Spring expansion, Summer productivity, Fall preparation, or Winter survival all shape what you look for and how you respond. In the end, the goal is not simply to look at bees, but to read the story they are telling about their health, productivity, and future plans. Good observation and study should lead to greater colony understanding and increased chances of self-sustainability.
