How to Safely and Effectively Get Rid of Bumble Bee Nests in the Ground
Bumble bees are generally considered beneficial insects, playing a crucial role in pollination. However, when they establish a nest in an inconvenient location, such as the ground in your yard, they can pose a stinging threat, especially to those with allergies. While it’s often best to leave them undisturbed, understanding how to safely and effectively remove a bumble bee nest from the ground is essential if their presence becomes problematic.
This comprehensive guide provides detailed steps and instructions for dealing with ground-nesting bumble bees while prioritizing safety and, where possible, the bees’ well-being. Remember, caution is paramount, and knowing your limitations is crucial. If you’re uncomfortable dealing with bees or are allergic to stings, contacting a professional pest control service specializing in bee removal is always the safest option.
## Understanding Bumble Bee Behavior and Nesting Habits
Before attempting any removal method, it’s crucial to understand bumble bee behavior and nesting habits. This knowledge will help you approach the situation safely and effectively.
* **Bumble Bee Life Cycle:** Bumble bees are social insects that live in colonies, though their colonies are significantly smaller than those of honey bees. The colony is founded in the spring by a single queen who emerges from hibernation. She selects a suitable nesting site, lays eggs, and tends to the first generation of workers. As the colony grows, the workers take over the tasks of foraging for nectar and pollen, building and maintaining the nest, and caring for the developing brood. In late summer or early fall, the colony produces new queens and males (drones). The original queen, workers, and drones die off at the end of the season, leaving only the newly mated queens to overwinter and start new colonies the following spring.
* **Nesting Preferences:** Bumble bees are opportunistic nesters and often choose pre-existing cavities in the ground, such as abandoned rodent burrows, vole tunnels, or even compost heaps. They prefer dry, sheltered locations that are easily accessible. Unlike honey bees, bumble bees don’t build intricate honeycombs. Instead, they create small wax cells to store nectar and pollen and rear their young.
* **Defensive Behavior:** Bumble bees are generally docile and unlikely to sting unless they feel threatened or their nest is disturbed. However, they can become aggressive if they perceive a danger to their colony. Stings are painful and can cause allergic reactions in some individuals. Approaching a bumble bee nest cautiously and minimizing vibrations is essential.
* **Identifying Bumble Bees:** Bumble bees are easily recognizable by their large size, fuzzy bodies, and black and yellow (or orange) stripes. They are important pollinators of many crops and wildflowers. It’s important to correctly identify them as bumblebees before taking any action, as other ground-nesting insects may require different removal strategies. Check for characteristics like size, hairiness, and the presence of a stinger (though observe from a safe distance!).
## Assessing the Situation
Before taking any action, carefully assess the situation to determine the size of the nest, its location, and the level of bee activity. This will help you choose the most appropriate removal method and take necessary precautions.
* **Locate the Nest Entrance:** Observe the area where you suspect the nest is located. Look for a small hole in the ground, often concealed by grass or vegetation. Watch for bees entering and exiting the hole to confirm the nest’s presence. Note the exact location of the entrance.
* **Estimate Nest Size:** While it’s impossible to know the exact size of the colony without excavating the nest, you can estimate it by observing the number of bees entering and exiting the nest. A high level of activity suggests a larger colony.
* **Assess Proximity to High-Traffic Areas:** Determine how close the nest is to areas where people frequently walk or play. If the nest is located in a high-traffic area, the risk of stings is higher, and removal may be necessary.
* **Consider Alternatives:** Before resorting to removal, consider whether it’s possible to simply avoid the area around the nest. If the nest is located in a less-traveled part of your yard, you may be able to coexist with the bees without any problems. Remember, bumble bees are beneficial insects, and their presence is a sign of a healthy ecosystem.
* **Check Local Regulations:** Some areas may have regulations regarding the removal of bee nests. Check with your local authorities to ensure you’re following all applicable laws and guidelines.
## Safety Precautions
Safety is paramount when dealing with bumble bee nests. Always take the following precautions to minimize the risk of stings:
* **Wear Protective Clothing:** Wear long sleeves, long pants, gloves, and a bee veil or hat with netting to protect your face and neck. Light-colored clothing is preferable, as dark colors may attract bees.
* **Work at Night or Early Morning:** Bumble bees are less active at night or early morning when temperatures are cooler. This is the best time to approach the nest.
* **Use Red Light:** If working at night, use a red light, as bees cannot see red light as easily as white light.
* **Avoid Strong Scents:** Do not wear perfumes, colognes, or scented lotions, as these can attract bees.
* **Stay Calm and Move Slowly:** Avoid sudden movements or loud noises, as these can agitate the bees. Approach the nest calmly and move slowly.
* **Have an Escape Route:** Always have an escape route planned in case the bees become aggressive.
* **Inform Others:** Let family members or neighbors know you are dealing with a bee nest and ask them to stay away from the area.
* **Keep Pets Indoors:** Keep pets indoors while you are working near the bee nest.
* **Have an Epinephrine Auto-Injector (EpiPen) Ready:** If you are allergic to bee stings, always carry an epinephrine auto-injector (EpiPen) and ensure someone is with you who knows how to administer it in case of an emergency.
## Removal Methods
Several methods can be used to remove bumble bee nests from the ground. The most appropriate method will depend on the size of the nest, its location, and your comfort level. It’s vital to remember that complete extermination should be a last resort, considering the bees’ ecological importance.

### 1. Relocation (The Most Humane Option)
Relocating the bumble bee nest is the most humane option, but it’s also the most challenging and requires specialized knowledge and equipment. It’s generally best left to experienced beekeepers or pest control professionals specializing in bee relocation.
**Here’s a general overview of the relocation process:**
* **Preparation:** Gather the necessary equipment, including a bee suit, smoker, shovel, lidded container (such as a cardboard box or plastic tote), and a new nesting site (e.g., a wooden box filled with straw or dry grass) in a suitable location away from human activity.
* **Timing:** The best time to relocate a bumble bee nest is at night when the bees are less active and all the workers are inside the nest.
* **Smoking the Nest:** Gently puff smoke into the nest entrance to calm the bees. A smoker is a device that burns dried plant material to produce cool smoke, which disorients the bees and reduces their aggression.
* **Excavating the Nest:** Carefully dig around the nest entrance, exposing the entire nest structure. Use a shovel to gently lift the nest out of the ground.
* **Transferring the Nest:** Carefully transfer the nest and all the bees into the lidded container. Be as gentle as possible to avoid disturbing the bees.
* **Sealing the Container:** Securely close the lid of the container to prevent the bees from escaping. Make sure there are ventilation holes in the lid to allow the bees to breathe.
* **Moving the Nest:** Transport the container to the new nesting site, taking care to avoid bumps and jolts.
* **Releasing the Bees:** Open the container and allow the bees to exit and explore their new surroundings. Place the new nesting site near the container to encourage the bees to move into it.
* **Monitoring the Nest:** Monitor the nest for several days to ensure the bees have successfully relocated and are thriving in their new home.
**Why Relocation is Difficult:**
* **Finding the Queen:** The success of relocation depends on capturing the queen. Without the queen, the colony will not survive.
* **Nest Integrity:** Bumble bee nests are fragile and easily damaged during excavation and transportation.
* **Bee Stress:** Relocation can be stressful for the bees, which can reduce their chances of survival.
**When to Consider Relocation:**
* When you want to avoid killing the bees.
* When you have the necessary skills, equipment, and time.
* When you have a suitable relocation site.
### 2. Covering the Nest Entrance (Temporary Solution)
Covering the nest entrance is a temporary solution that can discourage the bees from using the nest. However, it’s not a permanent solution, as the bees may find another entrance or dig their way out. This should only be used when another method can be implemented soon after, or in conjunction with another method.
* **Materials:** You will need a large rock, a piece of plywood, or a similar heavy object to cover the nest entrance.
* **Timing:** The best time to cover the nest entrance is at night when the bees are less active.
* **Procedure:** Carefully place the heavy object over the nest entrance, ensuring it completely covers the hole and prevents the bees from entering or exiting. Weigh it down with additional rocks or soil to prevent the bees from pushing it aside.
* **Monitoring:** Monitor the area for bee activity. If the bees find another entrance or dig their way out, you will need to try a different method.
**Limitations:**
* The bees may find another entrance.
* The bees may dig their way out.
* This method is not suitable for nests in high-traffic areas.
### 3. Using Diatomaceous Earth (DE) (Insecticide-Free Option)
Diatomaceous earth (DE) is a naturally occurring, non-toxic powder made from fossilized diatoms (a type of algae). It works by damaging the exoskeletons of insects, causing them to dehydrate and die. Food-grade DE is safe for use around humans and pets, but it can be harmful to bees if applied directly to them. Use with caution and avoid applying it on flowering plants where bees forage.
* **Materials:** You will need food-grade diatomaceous earth and a duster or powder applicator.
* **Timing:** The best time to apply DE is at night or early morning when the bees are less active.
* **Procedure:** Using a duster or powder applicator, puff a small amount of DE into the nest entrance. Avoid applying too much, as this can clog the entrance and prevent the bees from leaving. You can also create a perimeter around the nest entrance.
* **Repeat Application:** Reapply DE after rain or watering, as it loses its effectiveness when wet.
**Considerations:**
* DE can be harmful to bees if applied directly to them. Avoid applying it on flowering plants where bees forage.
* DE is not effective when wet.
* This method may take several days to be effective.
### 4. Nematodes (Beneficial Roundworms)
Beneficial nematodes are microscopic roundworms that parasitize insect pests in the soil. Some species can target ground-nesting insects. They are a natural and environmentally friendly option.
* **Materials:** Purchase a nematode product specific to ground-dwelling insects that is safe for pollinators.
* **Application:** Follow the product instructions carefully. Typically, you’ll mix the nematodes with water and apply the solution to the soil around the nest entrance.
* **Timing:** Apply in the evening or on a cloudy day to prevent the nematodes from drying out quickly.
* **Watering:** Keep the soil moist for several days after application to help the nematodes move through the soil and find their targets.
**Considerations:**
* Results may take several weeks.
* Effectiveness depends on soil conditions and nematode species.
* Ensure the product is safe for pollinators to minimize any unintended harm.
### 5. Flooding the Nest (Not Recommended, Can be Inhumane)
Flooding the nest is a method that involves pouring water into the nest entrance to drown the bees. However, this method is not recommended, as it can be inhumane and ineffective. It can also damage the surrounding soil and vegetation. The bees may also simply rebuild elsewhere. If this method is still being considered, take the following into account.
* **Materials:** You will need a garden hose and a large amount of water.
* **Timing:** The best time to flood the nest is at night when the bees are less active.
* **Procedure:** Place the garden hose into the nest entrance and turn on the water. Continue flooding the nest for several hours, ensuring the entire nest is saturated.
* **Aftermath:** After flooding, cover the nest entrance with soil to prevent the bees from returning. If you choose to fill in the nest, ensure all bees have vacated the nest.
**Cons:**
* This method can be inhumane, as the bees may suffer before they drown.
* This method can be ineffective, as the bees may survive by clustering together in the nest or by finding air pockets.
* This method can damage the surrounding soil and vegetation.
* The bees may rebuild the nest in the same location or nearby.
* This method may not be practical in areas with poor drainage.
### 6. Insecticide Dust (Last Resort, Use with Extreme Caution)
Using insecticide dust is a last resort option that should only be considered if all other methods have failed. Insecticides can be harmful to bees and other beneficial insects, as well as to humans and pets. If you choose to use insecticide dust, follow the instructions on the label carefully and take all necessary precautions.
**Important Note:** This method should only be used by experienced individuals who are familiar with the safe handling and application of insecticides. Always wear protective clothing, including gloves, a respirator, and eye protection.
* **Materials:** You will need an insecticide dust specifically labeled for use on bees. Look for products containing ingredients like carbaryl or permethrin. A duster or powder applicator is also required.
* **Timing:** The best time to apply insecticide dust is at night or early morning when the bees are less active.
* **Procedure:** Using a duster or powder applicator, puff a small amount of insecticide dust into the nest entrance. Avoid applying too much, as this can contaminate the surrounding soil and vegetation.
* **Covering the Entrance:** After applying the insecticide dust, cover the nest entrance with soil or a rock to prevent bees from escaping and to minimize exposure to other animals.
* **Monitoring:** Monitor the area for bee activity. If the bees are still active after a few days, you may need to reapply the insecticide dust.
**Risks and Considerations:**
* Insecticides can be harmful to bees and other beneficial insects.
* Insecticides can contaminate the surrounding soil and vegetation.
* Insecticides can be harmful to humans and pets.
* Always follow the instructions on the label carefully.
* Wear protective clothing when applying insecticides.
* Store insecticides safely out of reach of children and pets.
* Dispose of empty insecticide containers properly.
## Post-Removal Measures
After removing the bumble bee nest, take the following measures to prevent future infestations:
* **Fill in the Nest Hole:** Fill in the nest hole with soil or gravel to prevent other insects or animals from using it as a nesting site.
