Understanding who threatens a hive helps protect honey bees and the food they produce. Large mammals like bears can smash hives for brood and honey, while mid-sized animals such as skunks and raccoons damage lids and entrances. Small parasites, notably varroa mites, feed on worker fat bodies and spread viruses that weaken colonies.
Other pests, including small hive beetles and wax moth larvae, ruin comb and ferment honey, forcing colonies to abscond when infestations are severe. Birds and nocturnal invaders can take adult bees or nesting material from solitary nests, adding pressure across seasons.
This article maps the landscape of threats, the cost in time and money when hives are damaged, and practical defenses. Expect guidance on electric fencing for bears, entrance reducers and elevated stands for skunks, mouse guards for winter, mesh guards for solitary nests, and integrated pest management for varroa mites.
Key Takeaways
- Recognize field clues such as torn comb, scattered bee parts, or fermented honey to act early.
- Protect hives with targeted defenses: fences, straps, entrance reducers, and mouse guards.
- Monitor and treat varroa mites regularly as part of integrated pest management.
- Good apiary hygiene and stored-super care reduce beetle and moth risk.
- Seasonal patterns matter: spring, summer, and winter bring different pressures.
Why predators and pests matter to honey bees and bee colonies today
Modern apiary losses often trace back to a mix of parasites and animal incursions that sap colony strength. Varroa mites remain the single most damaging malady, feeding on adult and developing bees and spreading viruses that cause paralysis and deformed wings.
Tracheal mites further weaken adults by lodging in breathing tubes and limiting flight. Once a colony is stressed, small hive beetles can ferment stored honey and wax moths can destroy comb, especially in stored equipment.
Losses of workers, brood, and honey reduce a hive’s workforce and resilience. Fewer foragers mean less pollen and nectar return, so brood rearing slows and colonies consume stores faster than they can replace them.
- Parasites undermine immune function and amplify virus spread.
- Predation and pest pressure interact, inviting secondary pests into weakened colonies.
- Apiary impacts include robbed stores, contaminated comb, and added labor and replacement costs.
Proactive monitoring and prevention cut risk. Regular mite counts, maintaining strong colonies, good hygiene, and adjusting entrances all limit opportunities for intrusion. For practical foraging context and seasonal resource notes see foraging for nectar.
Bee predators
Common attackers around an apiary
From roaring bears to sit-and-wait ambushers, several species attack hives, adults, and stores. Bears topple boxes, tear brood chambers, and lick comb to reach honey and brood. Once a bear finds a source, it often returns unless excluded by a reliable electric fence.
Mammals near the apiary
Mammals: bears, skunks, raccoons, and opossums around the apiary
Skunks work at night, scratching entrances to draw out foragers and leaving wing piles and thoraxes on landing boards. Raccoons pry lids, scatter comb, and lift tops; opossums dig or pull at gear unless fences are buried at least 8 inches.
Birds that target adult bees and nesting materials
Starlings, swallows, robins, and woodpeckers take adults and nesting parts. Wire-mesh guard “bubbles” with 3/4″ openings and a 1.5–2″ to 3–4″ standoff protect nesting materials without harming wings.
Wasps, hornets, and yellowjackets preying on bees and brood
Late-season wasps and hornets raid for larvae, eggs, and nectar. These insects steal small workers and brood, forcing defensive flights that disrupt foraging.
Spiders and ambush insects capturing adult honey bees
Spiders trap adults in webs at flowers; mantises and dragonflies ambush on the wing. Remove webs near shelters and use sticky barriers to block crawling access.
| Threat | Typical Signs | Immediate Action | Deterrent |
|---|---|---|---|
| Bears | Toppled boxes, torn frames, licked comb | Resecure boxes, replace frames if needed | Electric fence, heavy straps |
| Skunks | Scattered wings, scratched boards at night | Reduce entrance, elevate hive | Raised stands, motion lights |
| Raccoons / Opossums | Disturbed lids, removed tops, shallow digging | Strap lids, bury fence 8″+ | Secure lids, buried perimeter fencing |
| Birds & Wasps | Missing adults, attacks at flights, raiding | Install mesh guards, trap paper wasp nests | Wire guard bubbles, wasp control |
- Field clues help ID the attacker quickly.
- Recurrent raids deplete adults and honey fast; act humanely but firmly.
Parasites and hive pests threatening honey bee colonies
Hidden pests and internal parasites sap colony strength long before obvious damage appears. Early detection limits losses and keeps hives productive.
Varroa mites: effects on adult honey bees, brood, and virus transmission
Varroa mites feed on fat bodies of adults and developing bees and reproduce in capped brood. This feeding weakens detoxification and immunity and amplifies viruses such as deformed wing virus. Successful beekeepers plan multiple mite checks and treat by season, keeping counts low before autumn to avoid winter losses.
Tracheal mites and signs of weakened adult bees
Tracheal mites live inside breathing tubes and cause crawling, disoriented adults with odd wing posture. These mites are not visible without lab work, so watch behavior and sudden declines in foragers.
Small hive beetles and wax moths
Small hive beetle adults and larvae spoil honey by fermenting stores. Look for slimy honey, beetles in corners, and larvae in comb; use traps, sanitation, and consult Extension for tougher controls.
Greater wax moth larvae tunnel and cover comb with silk, harming stored supers and weak colonies. Store equipment dry and below 40°F when possible and keep strong colonies to defend comb.
Nuisance insects and rodents
Spiders, earwigs, and cockroaches are usually harmless to the common honey bee and rank low among pests. Ants may be a nuisance under covers or in traps but rarely destroy brood.
Mice chew frames and foul comb in fall and winter. Install metal mouse guards and entrance reducers before cold weather and discard chewed comb in spring checks.
| Pest | Key Signs | Immediate Steps | Long-term Control |
|---|---|---|---|
| Varroa mites | Deformed wings, high mite counts, weak foragers | Monitor counts, treat as needed | Scheduled IPM treatments, brood break strategies |
| Small hive beetle | Slimy honey, larvae in comb, beetles visible | Sanitize, use traps | Maintain strong colonies, Extension-recommended controls |
| Wax moth | Silken webbing, burrowed comb in stored supers | Remove infested comb, freeze or cold-store supers | Store dry, rotate equipment, strong colony defense |
| Mice / Ants | Chewed frames, droppings, ants under covers | Install guards, clean and replace fouled comb | Seasonal guards, reduced entrance size |

How to recognize predator and pest pressure in your apiary
Field checks reveal most problems early. Walk the yard at dawn and note damage at the landing board and box edges.
Field clues:
- Wing piles and thoraxes by the entrance often mean skunks worked the hive at night.
- Ripped lids, scattered frames, or fur caught on wires point to raccoons or larger mammals; toppled stacks and licked comb signal a bear visit.
- Silken sheets and tunneled comb show wax moth activity; slimy, sour-smelling honey and trails of larvae indicate small hive beetles.
- Webs near boxes or nests flag spider pressure on solitary nests; clear and trim nearby brush and remove webs.
Seasonal patterns:
- Expect spring skunk activity as insect prey returns.
- Late-summer wasps and yellowjackets increase raids when natural foods fall.
- Winter brings mice and nesting risks; store weak equipment cold to reduce wax moth pressure below 40°F.

Protecting bee hives: practical defenses and management
Simple, well-maintained defenses often stop most attacks before they cost time or honey. Start with a perimeter plan and routine checks so small issues do not become big losses.
Electric fencing for bears and perimeter control
Install a dedicated bee-yard fence powered by batteries, solar, or plug-in energizers and test the charge regularly. Clear vegetation from wires to avoid grounding and maintain continuous power; an uncharged fence will not stop a bear and invites repeated visits.
Elevated stands, entrance reducers, and securing lids
Raise hives to discourage skunks and make strikes less likely. Use poultry netting or stands that expose skunk bellies to stings and fit entrance reducers so smaller colonies can defend the opening.
Secure tops with ratchet straps or a heavy rock to keep raccoons from lifting lids. A well-seated cover is a simple, effective deterrent.
Monitoring and treating varroa with an IPM plan
Write a seasonal IPM plan: schedule mite counts, rotate approved treatments, and plan more than one application per year. Keeping loads low before fall reduces winter losses and preserves adult health.
Wire mesh guards and spacing to protect nesting materials
Protect solitary nests with a wire-guard “bubble” using 3/4″ mesh and a 1.5–2″ to 3–4″ standoff. This shields nesting materials from birds or dexterous mammals without harming wings or deterring occupancy.
Apiary hygiene: preventing hive beetles and wax moths
Remove burr comb, wax scraps, and honey spills promptly to avoid attracting wasps and beetles. Store empty supers dry and cool to deny wax moths the conditions they need to thrive.
Deterrents for crawling threats: sticky barriers and placement
Apply Tanglefoot or a thin layer of Vaseline to shelter legs to block ants and other crawlers. Prune vegetation that creates bridges from the ground to stands and check that fence skirts or buried edges stop digging animals.
Tip: Keep a short log of inspections and charges on fencing; regular checks beat surprises.

Predators and resources: impacts on honey bees vs. solitary bees
When floral resources run low, managed hives can alter local foraging patterns and affect native pollinators.
Abundant honey from managed colonies may outcompete solitary species for nectar and pollen in tight landscapes. This is most clear where few flowering plants occur. Reduced visits to native nests can lower egg laying and cocoon survival for mason and leafcutter species.
Reduce competition with habitat planning: diversify native blooms across seasons, cluster plantings, and avoid stocking densities that overwhelm local resources. These steps support bumble bees and other species while keeping honey production steady.
Competition, nest protection, and crawling nuisances
Protect solitary nests with a 3/4″ wire-mesh guard set 1.5–2″ away from tubes, up to 3–4″ if needed. This blocks birds and dexterous mammals while allowing adult bees to access cells.
Apply Tanglefoot or AntCant to mounting legs to stop ants and earwigs. Remove vegetation bridges so crawling pests cannot reach exposed eggs or loose cocoons.
| Issue | Sign | Action | Notes |
|---|---|---|---|
| Forage competition | Fewer native visits, low brood | Plant diverse natives, reduce hive density | Helps bumble bees and solitary species |
| Birds / mammals | Disturbed nests, missing larvae | Install 3/4″ mesh guard, appropriate standoff | Remove guard when threat drops |
| Ants / earwigs | Damaged eggs, chewed cocoons | Use sticky barriers, clear bridges | Check regularly in spring and fall |
Tip: In bear country, mount houses 8–10 ft high only where needed; most solitary pollinators forage low, so keep placement practical.
Regional context in the United States: current risks and actions to take now
Local climate and wildlife determine top risks to your apiary. In bear country—from the Appalachians to the Rockies and the Pacific Northwest—install and maintain a charged electric fence before problems begin. A working fence is the first-line defense; an uncharged line invites repeat visits.
Spring often brings skunk pressure near the ground. Use elevated stands and entrance reducers early to protect small colonies and reduce night-time losses.
Late summer increases wasp and yellowjacket raids as natural foods decline. Keep hives strong and reduce open comb to limit robberies.
Work with local experts: contact your Cooperative Extension for hive beetle treatment options and alert state agriculture officials if you suspect Asian giant hornet sightings. Standardize hygiene: tidy wax and honey spills and store supers dry and off the ground.
Make varroa IPM a calendar item. Schedule sampling and treatments around local nectar flows and dearths, and match stocking rates to available forage. Plant native blooms to extend the summer nectar window and reduce stress on colonies and honey yields.
| Region / Season | Common Risk | Immediate Action | Ongoing Measure |
|---|---|---|---|
| Appalachia / Spring | Skunks, ground-level raids | Raise hives, reduce entrances | Elevated stands, early checks |
| Rockies / Year-round | Bears | Install/repair electric fence | Test charge frequently, perimeter clearing |
| Pacific NW / Late summer | Wasps, yellowjackets | Close exposed honey, install traps | Maintain colony strength, forage plantings |
| Nationwide | Hive beetle, varroa, Asian giant hornet (rare) | Contact Extension or state ag | IPM schedule, store supers dry off ground |
