What do wasps eat? That’s a question that many people have, especially those who are scared of wasps. Wasps are actually beneficial to have around because they help to pollinate and they eat other insects that can be harmful. So what do wasp eat? Mostly they eat nectar from flowers, but they also eat other insects like flies and caterpillars.

There are a variety of wasp species, and each one feeds on different types of insects.

Wasps are advantageous in the garden because they prey on other insects that can damage plants. This makes wasps an important part of the food chain and helps to keep insect populations under control.

What Do Wasps Eat?

Wasps aren’t finicky creatures. They eat a little bit of everything. Here are their favorite items to dine on:

what do wasps eat


Wasps eat various bugs, including caterpillars, spiders, and aphids. They also ingest nectar from flowers and fruit.

Wasps are beneficial in controlling pests, but they are also important for the pollination of flowers.

In gardens, wasps help control the populations of harmful bugs like caterpillars, aphids, and whiteflies by predating on them. Eating these pests helps keep the garden healthy and productive.

While wasps can be pesky in certain circumstances, they can also benefit farmers. 



Honeydew is the sap that has been drained from a plant or tree by an insect. The most common sap-suckers are aphids, mealybugs, and whiteflies. When these insects feed on a plant, they excrete a sugary honeydew liquid.

This liquid is high in sugar and provides an important food source for many different types of animals, including wasps.

Honeydew is a sweet, sticky liquid. The honeydew provides the necessary nutrients for the wasp colony to thrive. In addition, the honeydew helps to keep the wasps from becoming lethargic and allows them to move around with ease.

Human Food

Wasps are omnivorous insects, and one of their favorite food sources is human food. They will scavenge for food at picnics, outdoor events, and in garbage cans. They also like to eat sweet things like fruits and juices.

Wasps are attracted to food that is easily accessible and high in sugar. If you see wasps around your property, they’re likely looking for something to eat. 

To avoid wasps, make sure that all your food sources are locked down tightly. Wasp activity increases when they can easily find food, so take the necessary precautions to keep them away.

Fruit and Nectar

Common sources of food for wasps include fruit, nectar, and sweets. They also enjoy nectar, which is a sugar-rich liquid produced by flowers. This makes them a nuisance for people trying to enjoy outdoor activities in the summertime.

If you have an orchard or a single fruit tree in your yard, the fruit will attract wasps. The wasps will feed on the fruit and lay their eggs inside the fruit. As a result, you may have a lot of wasp larvae in your fruit.

In addition to fresh fruit, wasps love rotting fruit as well. This is because the sweet juices and fermenting sugars in rotting fruit are excellent food sources. They also enjoy drinking nectar from flowers, so you will often see them hovering around gardens and parks.

Honey is the primary food source for wasps. They will rob hives of their honey if they become weak and are susceptible to being attacked.

When it comes to what wasps eat, honey is a primary food source for many different species of wasps.

If you are a beekeeper or have any food with honey in your vicinity, you are likely to have wasps hanging around you or your yard. This can be problematic if the wasps start to nest near your property since they can be very aggressive when defending their territory.


Wasps are beneficial to plants as pollinators. They transfer pollen from one flower to another, which helps the plants reproduce. In addition, wasps help to control populations of harmful insects.

In addition to drinking nectar, wasps also enjoy pollinating plants. Some of the plants they particularly like include spearmint, sweet fennel, and Queen Anne’s Lace.

Do Wasps Eat Flies?

Yes, wasps do eat flies. In fact, wasps will eat just about any type of insect, including bees, beetles, and moths. Wasps are actually very beneficial to have around because they help to control the population of harmful insects.

Do wasps eat aphids?

Wasps are known to be important predators of many different types of insects, including aphids. While wasps will eat a variety of different foods, they seem to prefer prey that is high in protein.

Aphids are an ideal food source for wasps because they are small and easy to catch, and they contain a high amount of protein.

do wasps eat gnats?

One animal that enjoys snacking on gnats is the wasp. Wasps are predators that hunt other insects for food. While they will eat just about any type of insect, gnats are one of their favorites.

do wasps eat ants?

A wasp is any insect of the order Hymenoptera and suborder Apocrita that is not a bee or an ant. This means that wasps can eat ants, but do not necessarily do so.

Some species of wasps are known to be predators of ants, while others scavenge for food and are not particular about what they eat.

How Do Wasps Hunt?

There are three primary ways that wasps hunt for their prey: sight, smell, and taste. Wasps use their eyesight to scan their surroundings for potential food sources.

They also use their sense of smell to track down food and can even taste items in the air to determine whether or not they are edible.

Another common hunting strategy that wasps use is stalking their prey. By patiently waiting for the right opportunity, they can snatch the prey up quickly and easily.

When wasps hunt for food, they first identify their target. They then proceed to sting the target with venom, paralyzing it. Once the prey is paralyzed, the wasps would carry it back to their nest and feed their young.

When Do Wasps Eat?

Like many other animals, wasps display diurnal and nocturnal activity. This means that they are active during the day or at night.

This affects their eating habits- wasps that are active during the day are more likely to eat fruit, while those active at night are more likely to eat insects.

Nocturnal wasps have larger ocelli than diurnal wasps, which aids in their night vision.

How Often Do Wasps Eat?

Wasps are active during the warmer months and eat much more frequently. The number of insects preyed upon by wasps is higher during the warmer months, as there is a greater abundance of food.

Like other living creatures, wasps have different diets based on their age. Young wasps feed mainly on insects, while older wasps consume more nectar.

In the winter, wasps rely heavily on fruit nectar for sustenance. This means they do not scavenge as much as they do in the summer and are more likely to starve. While some wasps hibernate over winter, others die off. This is due to the colder temperatures and a lack of food.

How Do Wasps Benefit a Garden?

Wasps are beneficial to a garden because they help with pollination.

In addition to their role in pollination, wasps also get rid of plants and harmful insects. This helps keep the garden healthy and free from pests.

When a wasp paralyzes its prey with venom, it leaves larvae inside the host insect to feed. The nymphs will survive there until they are ready to pupate and become adults.

However, they also have a harmful side. Some species of wasps can be quite aggressive and sting humans or other animals.

Why are wasps more aggressive in fall?

Wasps are more aggressive in fall because they are searching for food. In the fall, wasps are looking for food and a place to hibernate. This can make them more aggressive as they search for these items.

Wasps feed on insects with higher toxicity levels in fall. This makes the wasps more fierce as they search for food and make them more dangerous to humans.

Interestingly, the increased aggressiveness of wasps in the fall is due to their increased toxicity due to their predating insects. The venom of a wasp becomes more potent as the weather gets colder, which helps protect the colony from predators and parasites.

One method to get rid of wasps is to watch for their nests and destroy them. 

  • You can also use traps or insecticides to get rid of them.
  • Removing a wasp nest is the first step in getting rid of these pests. You can either do it yourself or hire a professional.
  • Wear protective gear when you’re dealing with nests, as they can be dangerous.
  • Clean up your yard debris regularly. You will remove their food sources and make your property less appealing to them by doing this.

Final Thoughts

Wasps are a crucial part of the ecosystem and can help manage pests on a farm. They are predators of many different insects and help keep populations in check.

While wasp nests provide interesting insights into their diet and habits, they can also be dangerous. People should always be cautious when approaching a wasp nest and should never try to remove it independently.

When wasps are removed from their colonies, they may leave behind other pests that can be difficult to control. In some cases, these pests can cause significant damage to crops or structures. It is important to recognize this before taking any action to exterminate a wasp colony.
