Wasps can turn a sunny backyard afternoon into a nerve-wracking experience. Whether you’re enjoying a BBQ or simply tending your garden, the sudden appearance of these buzzing insects can send anyone running for cover. Unlike bees, wasps are aggressive and can sting multiple times, making them a serious concern for households, especially those with children or pets. Their nests can pop up under eaves, attics, or even underground, creating hidden threats that aren’t always easy to spot until it’s too late.
Australia, in particular, faces frequent wasp infestations due to its warm climate, making wasp control a necessary part of property maintenance. But before you grab a can of spray or attempt to knock down a nest yourself, it’s important to understand the most effective and safest extermination methods. This blog will cover the top 10 wasp extermination strategies that work. These methods range from DIY techniques to professional pest control solutions, so whether you’re dealing with a small issue or a full-blown infestation, you’ll find the right approach here.
Find and Identify the Nest
Before you do anything, the first step is to find the source. You must look in every nook and corner in your house, as nests are often located underneath roof eaves, in sheds, bushes, or even in enclosed walls. Knowing the type of wasp you are dealing with (paper wasps, yellow jackets, or European wasps) can also help you determine how to exterminate them if necessary.
Pro Tip: Never disturb a wasp nest without a strategy. Wasps are highly territorial and aggressive animals.
Wasp Spray (Aerosol Insecticide)
Wasp spray is the best solution for small quantities of wasps. Commercial wasp sprays by commercial pest control Melbourne are specifically designed for wasps, are very effective, and have a long-distance dispersal (4–6 m).
How to use:
- Spray early in the morning or at night when the wasps are least active.
- Spray directly into the entrance of the nest.
- Make sure to wear protective clothing in case of retaliation.
Utilise Wasp Traps
Wasp traps attract wasps using a drawn in sweet substance, like sugar water, fruit juice or meat. Once they enter, they cannot escape and will eventually die. This can help with outdoor wasp control.
DIY: A simple homemade trap can be created using a plastic bottle, with the top portion cut off and inverted, baited with sugar water or soda.
Use Wasp Dust for Hidden Nests
If you have wasps that are flying in and out of a cavity wall or underground nest, wasp dust (also called insecticidal dust) is more effective than any spray. Wasp dust will be walked back to the nest by a foraging wasp and will slowly kill the entire nest of wasps.
Important: Wasp dust should only be applied in good dry weather and when the nest is inactive. Be sure to wear gloves and a mask.
Boiling Water (Underground Nests Only)
Pouring boiling water regularly is a simple and non-chemical way to kill an underground wasp nest.
Warning: This method may cause very agitated wasps to swarm. Be sure to wear protective clothing and be prepared to leave quickly.
Peppermint Oil Spray
Essential oils such as peppermint oil have been proven to be a wasp deterrent. A simple combination of peppermint oil and water (with a small amount of dish soap) can be sprayed around your windows, doors, and outdoor sitting areas to deter wasps.
Bonus: It smells nice to us and doesn’t harm pets.
Seal Entry Points and Eliminate Places to Nest
You can not just rely on extermination. After getting rid of a nest, remember to:
- Seal up any cracks in your walls, vents, or eaves of your house.
- Remove any food scraps, soda or sugary drinks and keep bins covered.
- Trim down any shrubs or trees that could be places for wasps to nest.
A wasp-free house will be equally unattractive to them.
Hang a Wasp Decoy Nest
A decoy wasp nest, which can be purchased online or DIY from paper bags, can drastically reduce wasp colonies.
This Wasp Extermination trick is most effective in the spring as wasps begin looking for nesting areas.
Soapy Water Spray
There is more than one way to kill wasps, and mixing some dish soap and water in a spray bottle is an effective method. The soap produces a clogging effect on the wasp’s breathing pores, and they will suffocate. This is a method for a few wasps or small nests.
Instructions:
- Mix 2 tablespoons of dish soap with water.
- Spray at the wasps or their nest.
- This is a safer, eco-friendly alternative to chemical sprays.
