If you keep honey bees in Eastern North Carolina, you’ve probably heard about honey bee feeding stimulants and essential oil additives. These products are usually mixed into sugar syrup and are designed to encourage bees to feed, build brood, and stay healthy when natural nectar is limited.
This guide from D & D Pest Control Co. explains what honey bee feed stimulants are, how essential oils like lemongrass and spearmint are used, when to feed, and important safety and common-sense tips so you can support your bees without creating new problems.
What Is a Honey Bee Feeding Stimulant?
A honey bee feeding stimulant is a liquid additive that you mix with sugar syrup, often used in:
- Late winter and early spring, when colonies need help building up
- Fall, when beekeepers are preparing hives for winter
- Times of nectar dearth, when natural forage is scarce
- Packages, nucs, swarms, and small or weakened colonies that need a boost
Most commercial products are based on a sugar or sucrose solution and contain a blend of essential oils, especially lemongrass and spearmint, plus an emulsifier to keep everything mixed smoothly.
Common Essential Oils Used in Bee Feed Stimulants
While exact formulas are proprietary, many feed stimulants on the market highlight similar ingredients:
- Lemongrass essential oil – Often used because its aroma somewhat resembles the bees’ own Nasonov pheromone. It can help attract bees to feed and may have antimicrobial properties.
- Spearmint essential oil – Also commonly included for its palatability and potential health benefits; research has shown mint oils can be safe and may positively affect bee health and honey composition when used correctly.
- Other essential oils (in some products) – Thyme, oregano, and other plant oils have been studied for their antimicrobial and mite-suppression properties, but they must be used carefully to avoid toxicity or stress to bees.
- Emulsifiers (such as lecithin) – Help keep the oils evenly dispersed in sugar syrup so bees receive consistent, low concentrations.
When properly formulated and used at label rates, these blends are designed to be safe for bees and supportive of strong, vigorous colonies.
What Do Bee Feed Stimulants Actually Do?
Feeding stimulants don’t replace good forage, but they can support colonies in several ways:
- Encourage bees to take sugar syrup – The smell and taste of essential oils can make syrup more attractive, helping bees consume feed faster when they need it.
- Support colony buildup – When used with 1:1 sugar syrup at the right time, stimulants can help packages, nucs, and small colonies build brood and draw comb more quickly.
- Help keep syrup fresh – Some essential oils have mild antimicrobial and antifungal activity, which can help reduce syrup fermentation or mold growth in feeders.
- Provide a calming effect – Many beekeepers use feed stimulants as a spray in place of smoke. The scent can help calm bees and reduce fighting when combining colonies or working in the hive.
Keep in mind: feeding stimulants work best as part of an overall bee-care plan that includes good nutrition, disease management, mite control, and hive placement.
When to Use Honey Bee Feed Stimulant – and When Not To
Good Times to Use Feeding Stimulants
- Late winter & early spring – To help colonies build up brood before the main nectar flow.
- During nectar dearths – To prevent colonies from starving when natural forage is scarce.
- With packages, nucs, and swarms – To encourage feeding and comb-building in new colonies.
- With weak or recovering colonies – As part of a plan to rebuild population along with good mite control and disease management.
In all of these situations, stimulants are typically mixed into 1:1 sugar syrup and fed through internal or entrance feeders according to label directions.
Times to Avoid or Limit Use
- During a strong nectar flow – Feeding significant amounts of sugar syrup (with or without stimulant) while honey supers are on can lead to sugar syrup being stored in honey combs, affecting honey quality and label integrity.
- Without mite and disease control – Feeding stimulants may help colonies grow, but they will not solve Varroa, nosema, or other health issues on their own.
- At very high essential oil concentrations – Overdosing essential oils, or using untested oils, can stress bees and may lead to sublethal or lethal effects according to some studies.
Store-Bought vs. Homemade Bee Feed Stimulant
Commercial Feeding Stimulants
Products like Honey B Healthy®, Pro Health™, and similar bee feeding supplements are widely available and specifically formulated for bees. They typically feature:
- Known ingredients and concentrations
- Clear label directions for mixing and use
- Consistent quality from batch to batch
For most backyard and sideline beekeepers, using a reputable commercial product is the simplest way to add essential oils safely to sugar feed.
Homemade Feed Stimulants
Some beekeepers prefer to mix their own essential oil blends for use in syrup. Typical home recipes use:
- Clean water and sugar to create a simple syrup
- Very small amounts of food-grade lemongrass and spearmint essential oils
- An emulsifier to help mix oil and water
If you decide to go the DIY route:
- Use only food-grade essential oils, never fragrance oils.
- Follow recipes from university extension or trusted, research-based sources.
- Keep concentrations very low – more is not better.
- Test new mixes on a small number of colonies and observe behavior and brood carefully.
Because research shows essential oils can have dose-dependent effects on bee physiology and behavior, moderation and caution are key.
Basic Steps for Using Honey Bee Feed Stimulant with Sugar Syrup
Every product is different, but most feeding stimulants are used in a similar way:
- Mix your sugar syrup.
For buildup and stimulation, many beekeepers use a 1:1 (by weight) sugar-to-water syrup in early spring and during dearths. - Add feeding stimulant per label directions.
Measure carefully and mix thoroughly so the oils are evenly distributed in the syrup. - Use a clean feeder.
Use internal feeders, top feeders, or entrance feeders that bees are already accustomed to. Clean feeders help prevent mold and fermentation. - Feed during appropriate conditions.
Feed when bees can take syrup down quickly and when robbing risk is manageable. Avoid open feeding near other beekeepers’ yards. - Monitor colonies.
Watch bee behavior, brood patterns, and syrup consumption. Adjust feeding schedules as natural nectar becomes available or as colonies reach desired strength.
If syrup develops an off odor or visible mold, discard it, clean your containers, and mix a fresh batch.
Frequently Asked Questions About Honey Bee Feed Stimulant
Will a feeding stimulant replace good nectar and pollen?
No. Feeding stimulants are supplements, not replacements for natural forage. Bees still need access to diverse nectar and pollen sources for long-term health. Sugar syrup and essential oil stimulants are mainly tools for specific times when bees need help.
Can feeding stimulants help control Varroa mites?
Some essential oils used in beekeeping have been studied as part of integrated pest management for Varroa mites, but feeding stimulants in syrup are not a stand-alone Varroa treatment. Always follow proven Varroa control guidelines and use EPA-registered or extension-recommended treatments when needed.
Is it okay to feed sugar syrup with stimulant while I’m making honey for sale?
Most beekeepers avoid feeding sugar syrup when honey supers are on for harvest, with or without stimulants, to keep marketable honey free of sugar syrup. Follow your local regulations and best practices to protect honey quality and your customers’ trust.
How often should I use a feed stimulant?
That depends on your goals, climate, and forage conditions. Many beekeepers use stimulants during specific windows (early spring buildup, fall feeding, or emergency dearths) rather than continuously throughout the year. Overuse is not necessary and may be counterproductive.
Can feeding stimulants attract pests?
Spilled syrup with or without stimulants can attract ants, yellow jackets, roaches, and other insects. Use tight feeders, avoid spilling around hives, and clean up any leaks promptly. If you have ongoing pest issues around your home or apiary, professional pest control can help you manage them without harming your bees.
