Wasps are one of the most common pest problems across Auckland, especially during the warmer months. While many people focus on avoiding stings, understanding what wasps eat can help explain why they gather around homes, gardens, and outdoor eating areas.
At Waspman, we often get asked why wasps suddenly appear around rubbish bins, fruit trees, or outdoor meals. The answer usually comes down to their diet and feeding habits.
Understanding what wasps eat can help you prevent infestations and identify early warning signs of a nearby wasp nest.
What Do Wasps Eat?
Wasps eat a mix of sugary foods and protein sources, and their diet changes throughout the season. In Auckland, one of the most common pest species is the common wasp, Vespula vulgaris, which follows this seasonal feeding pattern.
Adult Wasps Eat Sugary Foods
Adult wasps mainly feed on:
- Flower nectar -they also collect pollen while feeding
- Honeydew from trees
- Ripe or fallen fruit
- Soft drinks and sugary beverages
- Sweet human foods
- Jam and desserts
This is why wasps are especially active around outdoor dining areas and rubbish bins in Auckland homes.
In early summer, wasps begin foraging for sugary foods, but they become most noticeable in late summer when colonies grow larger and need more food.
What Do Baby Wasps Eat?
After the eggs hatch, wasp larvae need protein to grow. Understanding the wasp life cycle, worker wasps hunt insects and spiders — including native insects — and subdue prey to feed their young:
Worker wasps feed larvae:
- Caterpillars
- Flies
- Beetles
- Spiders
- Other small insects
The larvae produce a sugary liquid that adult wasps eat in return — creating a food-sharing system inside the nest.
This is one reason why wasp nests can grow extremely fast during summer.
Types of Wasps Found in Auckland
Auckland is home to many wasp species, including introduced wasps and other wasps. Different wasp species, along with other species, have slightly different diets, but most behave similarly.
Social Wasps / Asian Paper Wasps (Nest Material)
Social species of wasps build large nests from wood pulp, live in colonies, and aggressively defend them.
Common Auckland species include:
- German wasps
- Common wasps
- Asian paper wasps
These species build nests and aggressively defend them.
German and common wasps are particularly attracted to sweet foods and meat scraps, making them a frequent problem around homes.
Solitary Wasps
Solitary wasps live alone rather than in colonies.
They typically:
- Hunt insects or spiders
- Lay eggs inside captured prey
- Build small nests
Solitary wasps are usually less aggressive and rarely require pest control.
Why Wasps Come to Your Property
If wasps are regularly visiting your property, there is usually a reliable food source nearby.
Common attractants include:
- Fallen fruit
- Compost bins
- Pet food
- Rubbish bins
- Outdoor dining areas
- Flowering plants
- Sugary drinks
Properties with easy access to food are more likely to have nearby nests. At Waspman, we often find nests within 20–100 metres of feeding areas.
Do Wasps Help Control Other Insects?
Yes, wasps are natural predators.
Wasps help control important insects, including both pests and native insects, by eating:
- Caterpillars
- Flies
- Aphids
- Beetles
In small numbers, wasps can be beneficial to gardens.
However, large colonies, particularly German and common wasps, can become dangerous around homes and overwhelm the local ecosystem
Natural Predators of Wasps
Unfortunately there are few natural predators of social wasps in New Zealand due to the wasps being an introduced pest.
Why Wasp Populations Grow So Quickly in Auckland
Auckland’s warm, humid climate and long summers allow wasp colonies to grow rapidly coupled with often very mild winters that often allow nests to survive through the colder months.
A single nest can produce:
- Thousands of wasps with a queen able to lay up to 100 eggs a day
- Multiple female wasps (queens) -late in the season
- New colonies the following year
Large colonies need significant food, which is why heavy wasp activity near your property often signals a new nest nearby
How to Reduce Food Sources for Wasps
Reducing food sources can help discourage wasps from settling nearby.
Helpful steps include:
- Keep rubbish bins sealed
- Remove fallen fruit
- Cover outdoor food and drinks
- Clean outdoor eating areas
- Seal wall gaps and roof cavities
- Avoid leaving sugary drinks outside
Remember: These steps reduce attraction but do not remove existing nests.
Why DIY Wasp Control Often Fails
Many homeowners try to control wasps by:
- Spraying individual wasps
- Using supermarket insecticides
- Destroying visible nests
Unfortunately, this rarely solves the problem because:
- The main nest may be hidden
- Colonies contain thousands of wasps
- Wasps aggressively defend nests
- Insecticides are often misused
- Specialist equipment is often required to access the nest
Professional removal is the safest and most effective solution.
When to Call Waspman
You should consider professional wasp nest removal if you notice:
- Large numbers of wasps daily

Are Wasp Stings Dangerous?
Wasp stings are painful and can be serious:
Unlike honeybees, wasps can sting multiple times.
Health risks include:
- Pain and swelling
- Allergic reactions
- Infection
- Anaphylaxis in severe cases
Large nests increase the risk of multiple stings.
This is one of the main reasons homeowners choose professional nest removal.
FAQs
What attracts wasps the most?
Sugary foods and protein sources attract wasps the most. This includes fruit, soft drinks, meat scraps, and rubbish bins.
Do wasps eat mosquitoes?
Yes. Wasps eat many insects, including flies and mosquitoes, but do not significantly control mosquito populations.
Why are wasps worse in late summer?
Wasp colonies are largest in late summer, meaning more wasps are searching for food. Natural food sources also become scarce, so wasps target human food.
How do I know if a wasp nest is nearby?
If you see wasps regularly flying in and out of the same hole or area, a nest is likely nearby.
Conclusion
Wasps eat a wide variety of foods, including insects, nectar, and sugary human foods. Their flexible diet is one reason they thrive in Auckland and often become a nuisance around homes.
While wasps play an important role in the ecosystem, large colonies can quickly become dangerous.
Understanding what wasps eat helps explain why they appear — but removing the nest is the only permanent solution.
