How Do I Get Rid Of Mortar Bees In Australia?

In Australia, mortar bees australia can be exterminated using several different strategies. Listed below are some viable alternatives:

Seal The Holes

By filling in the openings, you can prevent the bees from reentering their nests and utilising that space again. A sealer or putty, both of which may be found at hardware and home improvement stores, can be used to plug the openings.

Find the entrances and exits the bees are using to their hives. After finding the holes, you should clean the area around them to remove any dirt or debris that could prevent the sealant from properly sticking.

After that, fix the gaps with sealer or putty as best you can. Make sure there are no voids left by spreading the sealant evenly with a putty knife or equivalent instrument. Follow the manufacturer’s directions for drying time before using the sealant.

Once the sealant has dry, you should inspect the area to make sure the bees are unable to find any new entry points. If you discover any further cracks or crevices, you should repeat the sealing process.

Bees already inside the nest will not be eliminated by plugging up the entrances. However, this will prevent them from going out to get food on their own. The bees will eventually starve to death, at which point you can safely dismantle the sealed nest.

Use Insecticide

If that doesn’t work, you can always try killing the bees with an insecticide. Before using, always check the label and adhere to the directions. Spray in an unoccupied area far from people, animals, and food, and always wear protective gear. Insecticides are a reliable tool for eliminating mortar bees, but they should be reserved for extreme cases. Here’s the procedure:


  • Identify the type of insecticide: Look for an insecticide that is specifically designed to kill bees. Some insecticides are labelled for use on masonry bees, so make sure to read the label carefully before purchasing.


  • Wear protective clothing: Wear long sleeves, pants, gloves, and a mask to protect yourself from the insecticide. It’s also a good idea to wear safety glasses or goggles.


  • Apply the insecticide: Spray the insecticide directly into the holes where the bees are entering and exiting. Make sure to follow the instructions on the label carefully, and avoid spraying near people, pets, or food. It’s best to apply the insecticide in the early morning or late evening when the bees are less active.


  • Repeat as necessary: Insecticides may require multiple applications to be effective. Follow the label instructions for reapplication, and be patient as it may take some time to see results.


Use caution while applying pesticides because they might kill off beneficial insects and other wildlife as well as the pests they target. Before turning to insecticides, try closing off the entry points and eliminating potential nesting areas. A professional pest control service should be called in when there is a significant infestation or when the homeowner is unclear about how to eliminate the pests.

Hire A Professional

It may be preferable to call a professional pest control firm if you have any doubts about how to tackle the situation or if the infestation is extensive. They’ll know what they’re doing and have the tools to get rid of the bees without causing any harm. 

A professional pest control service should be called in the event of a severe mortar bee infestation or if you are unsure how to eliminate the problem on your own. What to anticipate from a professional service provider is as follows.


  • Inspection: The pest control company will conduct a thorough inspection of your property to determine the extent of the infestation and the best course of action.


  • Treatment: Depending on the severity of the infestation, the pest control company may use a combination of methods such as insecticides, fumigation, or physical removal of the nests.


  • Safety precautions: Pest control professionals are trained to handle hazardous materials and take necessary precautions to ensure the safety of you, your family, and your pets. They will also provide guidelines on how to stay safe during and after the treatment.


  • Follow-up: The pest control company will schedule a follow-up visit to ensure that the treatment was effective and to address any remaining issues.


When hiring a pest control company, make sure to choose a reputable company with experience in dealing with mortar bees. Ask for references, check reviews online, and verify that the company is licensed and insured. It’s also a good idea to get a written estimate of the cost and the scope of the work to be performed.

Provide Alternative Nesting Sites

Providing mortar bees with other nesting sites is a humanitarian and environmentally-friendly strategy to get rid of them. Here’s the procedure:


  • Determine the preferred nesting sites: Mortar bees are attracted to sites that are dry, sheltered, and warm. Look for a sunny, south-facing spot on your property that is away from foot traffic and activity.


  • Install bee houses: Bee houses are wooden structures that provide nesting sites for bees. They come in various shapes and sizes and can be purchased online or at garden centres. Make sure to choose a bee house that is appropriate for the type of bees in your area.


  • Place the bee houses: Place the bee houses in the preferred nesting site, facing south, and at a height of about 2-3 meters above the ground. Make sure to secure the bee houses stably and sturdily.


  • Maintain the bee houses: Clean the bee houses regularly to prevent the build-up of dirt and debris. Some bee houses have removable trays that can be cleaned, while others require cleaning with a brush. Check the bee houses periodically to ensure that they are in good condition and to prevent infestations by pests such as mites.


By offering the bees an alternate place to nest, you may keep them from laying their eggs in your mortar and still benefit from the pollination of your garden. Though it may not eradicate the mortar bee infestation, providing alternate nesting locations will help lower the population and prevent further harm.


Even though mortar bees can do a lot of harm to your walls, there are various good techniques to get rid of them. To stop mortar bees from establishing a nest in your walls, just fill in the gaps and crevices you find. Insecticides should be used only as a last resort and natural bee habitats should be preserved whenever possible.

Hiring a professional pest control service is recommended if the infestation is extensive or if you lack confidence in your ability to eliminate the pests on your own. You can protect your home against mortar bees and foster a harmonious coexistence with these helpful hints.
