How to Eliminate Digger Bees from Potted Plants

Digger bees can be a nuisance for those who love to keep plants in pots or containers. These bees dig holes in the soil, disrupting the roots of plants and causing damage to the foliage. Thankfully, there are several ways to eliminate digger bees from potted plants.

Identify the Type of Digger Bee

The first step in controlling digger bees is to identify the type of bee species. Not all bees cause damage to plants, and some may even be helpful to have around. The two most common types of digger bees are ground bees and carpenter bees.

Ground bees, also known as mining bees, are small black or brown bees that dig holes in the ground to lay eggs. They feed on pollen and nectar and do not cause significant damage to plants. Carpenter bees, on the other hand, are larger bees that bore holes in wood or other plant material. They can cause extensive damage to wooden structures and plant stems.

Use Insecticides

Insecticides are an effective way to eliminate digger bees from potted plants. However, it is essential to read the labels and instructions carefully before using them on plants. Insecticides that contain pyrethroids or neonicotinoids are effective against bees but can be harmful to other pollinators.

It is best to use insecticides during the early morning or late evening when bees are less active. Apply the insecticide directly to the affected area and follow up with regular applications until the bees are under control.

Install Netting or Screens

Installing netting or screens over the potted plants is another effective way to eliminate digger bees. The netting or screens should be small enough to prevent bees from entering the planting container while still allowing for adequate air and light flow.

Note that this method may not work for plants that require pollination by bees or other insects, such as fruit trees or vegetables.

Repel Digger Bees with Natural Remedies

Repelling digger bees with natural remedies is a safe way to eliminate them from potted plants. Common natural remedies include essential oils such as peppermint, eucalyptus, and lavender. These oils can be mixed with water and sprayed directly onto the soil or plant foliage.

Citronella candles or torches can also be effective in repelling digger bees. Place them near the planting container or around the outdoor living area to keep the bees at bay.

Conclusion

Digger bees can be detrimental to potted plants but can be eliminated using several methods, such as insecticides, netting, and natural remedies. It is crucial to identify the type of digger bee and choose the appropriate method to control them safely and effectively.

By following the tips above, you can enjoy your potted plants without the nuisance of digger bees.
