How To Keep Stag Beetles Away

Pest Guides 9

Stag beetles are one of nature’s fascinating creatures. Known for their distinctive, antler-like mandibles, they play a crucial role in breaking down decaying wood in the ecosystem. However, their presence can sometimes be a nuisance, especially if they infest your garden or home. If you’re looking for ways to keep stag beetles away, you’re in the right place. This comprehensive guide will provide you with all the information you need to deter these majestic insects from your property effectively.


To keep stag beetles away, remove decaying wood from your property, use natural repellents like soapy water spray, set up traps, apply insecticides like pyrethrin or diatomaceous earth, and maintain a clean and tidy garden. Regularly inspect your garden for signs of stag beetle activity and use commercial products responsibly if necessary. Always consult with a professional pest control expert if you are unsure about the best approach.

Understanding What Attracts Stag Beetles

Before we delve into the prevention methods, it’s crucial to understand what attracts stag beetles to your property. Stag beetles are primarily attracted to decaying wood, which serves as their primary habitat and food source. They prefer oak woodlands but can also be found in gardens, hedgerows, and parks. Their larvae depend on old trees and rotting wood to live in and feed on. Adult beetles are also attracted to warm surfaces like tarmac and pavements. Furthermore, stag beetles may be drawn to areas with soft fallen fruit, such as cherries, as they can drink from them.

Steps to Deter Stag Beetles

Now that you know what attracts stag beetles let’s look at the various methods you can employ to keep them at bay.

Remove Decaying Wood

One of the most effective ways to deter stag beetles is by removing any decaying wood from your property. This includes dead trees, stumps, or wood piles. By eliminating their primary habitat and food source, you can significantly reduce their presence.

Use Natural Repellents

Natural repellents such as soapy water spray can be very effective. You can create this by combining one teaspoon of soap per 16 ounces of water in a spray bottle and apply it to areas where stag beetles are present. The soap not only repels stag beetles but also works to deteriorate their protective, waxy shell.

Set Up Traps

Traps, such as pheromone traps and light traps, can be used to capture and remove stag beetles from your property. These traps attract beetles using either light or pheromones and trap them inside.

Apply Insecticides

When the infestation is severe, you can use insecticides like pyrethrin or diatomaceous earth to control the beetle population. These insecticides are safe for humans but deadly to stag beetles.

Regularly Inspect Your Garden

Regularly inspect your garden for signs of stag beetle activity, such as holes in the ground or wood chips on the surface, and take appropriate action to remove them.

Maintain a Clean and Tidy Garden

Keeping your garden clean and free of debris and excess vegetation can provide hiding spots and breeding grounds for stag beetles.

Commercial Products to Repel Stag Beetles

There are several commercial products available that are effective in repelling or controlling stag beetles. These include diatomaceous earth, soapy water, traps, pyrethrin spray, and various insecticides like Bifen LP Granules and Supreme IT.

Remember, it’s important to use these products responsibly. Stag beetles are legally protected from sale in the UK and are considered a ‘priority species’. Always follow the instructions on the product label and consult with a professional pest control expert if you are unsure about the best approach.

Dealing with a Stag Beetle Infestation

If you’ve already got an infestation, don’t panic. The above methods can be used to control and manage the situation. Regularly inspect your property for signs of stag beetle activity and take appropriate action when needed.

Stag beetles are an important part of our ecosystem, and while they can sometimes be a nuisance, it’s essential to manage their presence without causing unnecessary harm to the environment. By implementing these measures, you can help control stag beetle populations and prevent infestations in your home and garden.
