Ever wondered why wasps keep buzzing around you during your Melbourne picnic?
Whether you’re hosting a BBQ in your backyard, spending a sunny afternoon at the Royal Botanic Gardens, or tending your veggie patch in the suburbs, wasps always seem to appear just when you least expect them.
But what if it’s not just the food or drink drawing them in?
What if the colours you’re wearing are sending wasps a visual invite?
This blog explores how wasps perceive colour, why certain clothing can make you more noticeable to them, and what you can do to stay safe outdoors in Melbourne.
Plus, if you’re noticing more than just a passing visitor, we’ll show you when it’s time to call in expert help with wasp nest control in Melbourne.
Do Colours Really Attract Wasps?
The short answer: yes.
Wasps have a sophisticated visual system that allows them to detect ultraviolet (UV) light — something the human eye can’t see.
This unique ability helps them locate food sources like flowers and fruit.
Unfortunately, it also means that your brightly coloured t-shirt or picnic rug might look a lot like a giant nectar source to a wasp.
Unlike humans, who perceive colours based on red, green, and blue cones, wasps perceive the world using UV, blue, and green. That means certain bright colours appear far more vibrant or attractive to wasps, especially those that reflect UV light strongly.
So while you may think you’re blending into the background in your white sundress, to a wasp you could be glowing like a flower in full bloom.
Colours That Attract Wasps the Most
Certain colours are far more likely to attract wasps than others. Here are the ones to avoid if you’re heading outdoors during Melbourne’s warmer months:
- Yellow – This colour closely resembles pollen and flower petals, which are food sources for wasps. Wearing yellow can make you look like a walking bloom.
- White – While it may seem like a neutral choice, white reflects UV light very strongly. That makes it highly visible to wasps and other insects that see in the UV spectrum.
- Blue – Especially lighter shades, which can resemble nectar-rich flowers. Insect vision often associates this with food.
- Black or Dark Colours – These don’t attract wasps as food but are often perceived as threats. Dark clothing can make you look like a predator to wasps, triggering defensive behaviour.
Bright and contrasting colours, particularly those that resemble natural sources of nectar or pose a perceived threat, are most likely to draw attention from nearby wasps.
Safe Colours to Wear Outdoors in Melbourne
So what should you wear if you want to enjoy the outdoors without unwanted insect attention?
Choose colours that are less stimulating to a wasp’s vision. These include:
- Muted greens – Blend in with your natural surroundings and do not resemble flowers.
- Beige or khaki – Earth-toned colours that don’t reflect UV light strongly.
- Brown and other earthy tones – These natural colours are generally ignored by wasps.
These clothing choices can help you stay under the radar during outdoor activities in areas like your backyard, city parks, or even a Yarra Valley picnic.
Outdoor Safety Tips for Wasp Prevention in Melbourne
While choosing your outfit is a good start, there are several other precautions you can take to avoid attracting wasps while enjoying the outdoors in Melbourne:
- Wear neutral or earthy-coloured clothing
As discussed, this helps you avoid drawing attention. - Avoid perfumes or scented body products
Floral or fruity fragrances can attract wasps, mistaking you for food. - Keep food and drinks covered
Wasps are drawn to sugary drinks, meats, and fruits – common at BBQs and picnics. - Use drink containers with lids
Avoid drinking straight from cans or open bottles, as wasps can crawl inside unnoticed. - Dispose of rubbish promptly
Especially sweet wrappers, fruit peels, and food scraps. - Remain calm if a wasp approaches
Sudden movements can startle wasps and provoke them to sting. - Avoid wearing bright accessories
Hats, bags, and even reflective sunglasses can catch their attention.
When Wasps Become a Bigger Problem
Occasional wasps during outdoor meals are one thing. But if you notice consistent wasp activity in a specific area of your home or garden, it could indicate something more serious — a nest nearby.
Here are signs to watch for:
- Increased wasp traffic around one area
If wasps are frequently flying in and out of the same location, there’s likely a nest. - Buzzing sounds from walls, roofs, or vents
Wasps often nest inside wall cavities, roof eaves, or behind vents. - Visible nest structures
These look like grey, papery hives and can be found under eaves, tree branches, sheds, or fences. - Aggressive wasp behaviour
Wasps tend to become territorial when they feel their nest is threatened.
Why You Should Avoid DIY Wasp Nest Removal
While it might be tempting to tackle a wasp nest on your own, the risks often outweigh the rewards.
Here’s why DIY isn’t recommended:
- Wasp stings are painful and can trigger allergic reactions
For some, a single sting can lead to serious medical emergencies. - Nests contain dozens to hundreds of wasps
Disturbing a nest without the proper technique or equipment can result in a swarm attack. - Incorrect removal methods can cause structural damage
Using sprays or smoke near walls, vents, or timber structures can cause harm to your property. - Professionals know how to safely locate and remove nests
Pest control technicians have protective gear, the right treatments, and experience managing wasp infestations.
