How to Get Rid of Thunder Flies

1. Identify the Infested Areas

Before you start, it’s important to identify where the thunder flies are most concentrated. Check your garden, indoor plants, and areas around windows and lights.

2. Use Sticky Traps

Sticky traps are an effective way to capture thunder flies. Place them near infested plants and around windows to catch the flies. These traps can be purchased from most garden centres or online.

3. Apply Insecticidal Soap

Insecticidal soap is a safe and effective way to control thunder flies. Spray the affected plants thoroughly, ensuring that you cover the undersides of the leaves where thunder flies like to hide.

4. Introduce Natural Predators

Beneficial insects like ladybugs and lacewings are natural predators of thunder flies. Introducing these insects to your garden can help control the thunder fly population naturally.

5. Keep Your Home Sealed

Prevent thunder flies from entering your home by sealing any gaps around windows and doors. Using fine mesh screens can also help keep these tiny pests out.

6. Maintain Cleanliness

Thunder flies are attracted to light and plants. Keeping your home clean and free of plant debris can reduce the likelihood of an infestation. Regularly vacuum and wipe down surfaces where thunder flies are seen.

Preventing Future Infestations

Regular Plant Inspection

Regularly inspect your plants for signs of thunder flies and other pests. Early detection can help you address the problem before it becomes a full-blown infestation.

Proper Plant Care

Healthy plants are less susceptible to pest infestations. Ensure your plants are well-watered, pruned, and fertilized to keep them strong and resilient against pests.
