For non aggressive wasps I've had great luck spraying the nests with this Spectracide wasp remover in the evening. For more aggressive wasps I also use this rediculous looking upper torso Beekeeping suit. It seems silly, but trust me, it's amazing.

What Do Wasps Eat?

Wasps are omnivores, which means they eat both plants and animals. Their diets can vary depending on the species of wasp and the time of year.

Adult Wasps

Adult wasps typically feed on nectar, fruits, and other sugary substances. They use these carbohydrates as a source of energy to fuel their activities, such as flying and building nests. Some wasp species also feed on pollen, which provides them with essential proteins.


While adult wasps primarily consume carbohydrates, their larvae have a different diet. The larvae feed on protein-rich foods, including insects, spiders, and even other small arthropods. Adult wasps hunt for prey and bring it back to the nest, where they feed the larvae.

Why is Knowing What Wasps Eat Important?

Understanding what wasps eat and how it affects their behavior can be helpful for homeowners. For example, if you notice wasps flying around your picnic area, it may be because they are attracted to the sugary drinks or food. By keeping your food and drink covered, you can help deter these pests from bothering you.

Additionally, knowing that wasp larvae feed on insects can help homeowners identify areas where they may have an insect infestation. If you see wasps frequently flying in and out of a particular area, it could indicate that there is a nest nearby, which should be addressed promptly.


In conclusion, wasps are omnivores that eat both plants and animals. Adult wasps primarily feed on nectar and other sugary substances, while their larvae consume protein-rich foods like insects and spiders. Understanding what wasps eat and how it affects their behavior can be helpful for homeowners to prevent infestations and reduce the risk of wasp stings. Remember to always take precautions when dealing with wasps, especially if you are allergic to their venom.
