Sasha CampbellIf you’ve ever wondered, “Are bats good for gardens?” the answer is yes in most cases.
The benefits of bats in the garden go far beyond eating insects. These fascinating mammals help control insect pests and support healthy ecosystems.
Benefits of Bats for Gardens (Plus How to Attract Them)
Below, we’ll see how bats can benefit your yard and garden. We’ll also look at some ways to attract them.
1. Help Control Pests in Gardens
Studies have shown that bats help farmers by feeding on insects that damage crops, reducing pest pressure on farms and in nearby landscapes [1].
Many bat species feed on insects that can damage crops in gardens. They feed on many flying insects, including beetles, armyworm moths, cutworm moths, leafhoppers, flies, and grasshoppers.
By eating adult moths, bats can also help reduce the number of caterpillars that hatch later.
Some insect-eating bats can consume hundreds to thousands of insects in a single night [2]. This amount depends on the species and the size of the insects available.
Welcoming bats may reduce the need for chemical pesticides. By eating large numbers of crop pests, they provide valuable natural pest control that can help farmers and gardeners save money while supporting a healthier garden ecosystem.
2. Help Lower Mosquito Numbers
Bats also bring benefits to your yard. If mosquitoes are a nuisance, bats may help reduce their numbers by preying on them as part of their overall insect diet.
Bats do eat mosquitoes, but mosquitoes usually make up only a small part of their diet. They eat far more moths, beetles, flies, and other flying insects.
Even though mosquitoes make up only a small part of their diet, bats may still help reduce local mosquito numbers [3].
This natural pest control is especially helpful in areas where mosquitoes are common or where diseases like West Nile virus are a concern.
3. Bats Are Pollinators
While bees often get all the credit for pollination, certain bat species are important pollinators [4].
In tropical and subtropical regions, certain bats that feed on nectar and fruit play a key role in pollinating plants. They pollinate agaves, cacti, baobab trees, durian trees, and many night-blooming flowers.
If you live in a region where nectar-feeding or fruit-eating bats are present, these animals may help pollinate some of these plants.
4. They Distribute Seeds
Fruit-eating bats also help distribute seeds [5]. This is essential for the spread of various plant species.
In tropical regions, for example, bats help disperse seeds from the fruits they consume. In tropical gardens, fruit bats may also spread seeds naturally, helping new plants grow.
5. Nutrient-Rich Fertilizer (Bat Guano)
Another reason why bats are good for gardens is that bat droppings (guano) are a rich natural fertilizer. They contain essential nutrients that plants need to grow.
Bat guano is high in nitrogen, phosphorus, and potassium, which are all vital for plant health.
Commercially processed bat guano sold as fertilizer is generally treated for garden use and should always be applied according to the label.
Fresh guano from wild bat roosts should never be used directly in the garden. It can contain fungal spores that may pose health risks.
6. Biodiversity Support
Bats not only benefit your plants but also support a healthy ecosystem. They help control insect populations and play a key role in the natural food web.
In turn, bats serve as prey for certain birds, mammals, and reptiles, helping keep nature in balance.
How to Attract Bats to Your Yard and Garden
Encouraging bats to visit your garden is not as hard as it seems. It can be as easy as creating a welcoming environment for them.
Below are five ways to attract them:
Install a Bat House
Putting up a good bat house is one of the most effective ways to attract bats.
A bat house is like a birdhouse but is specifically designed for bats. It gives bats a safe place to roost during the day. It also keeps them safe from certain predators.
Choose a bat house with several narrow chambers, as these are often more attractive to bats than single-chamber designs. Installing a bat house may encourage bats to roost there instead of under roof eaves or in other parts of your home.
For the best results, mount bat houses 12–20 feet above the ground. In many regions, bat houses perform best when they receive several hours of direct sunlight daily.
However, placement recommendations may vary depending on local climate.
Add a Water Source
Bats need fresh water, especially during hot summer weather.
Many bats drink while flying. This means that ponds, small water gardens, birdbaths with open access, and other shallow water features can be more appealing than small containers.
Create a Diverse Habitat
Bats like gardens with a mix of trees, shrubs, flowering plants, and other plants that mimic their natural habitat.
Tall trees provide shelter and roosting sites. Shrubs and flowering plants attract insects, giving bats more food to eat.
Minimize Artificial Lighting
Bats are sensitive to bright lights. They also prefer to hunt in darker conditions.
Therefore, consider reducing outdoor lighting or keeping it off unless needed. Reducing artificial lighting will make your backyard more attractive to bats.
Reduce the Use of Pesticides or Avoid Using Them Altogether
Since bats feed on insects, using fewer insecticides means they’ll have more food to eat.
Opt for other organic or natural pest control methods. This encourages a healthier habitat for bats and other beneficial creatures.
Plant Night-Blooming Flowers
You can also create a bat-friendly garden. Bats are drawn to fragrant, night-blooming flowers that provide nectar.
Try planting evening primrose, moonflower, and other fragrant, night-blooming flowers if nectar-feeding bats live in your area. These plants may also attract insects, providing bats with another food source.
Common Myths About Bats
- Bats are not blind.
- Very few bats have rabies, but you should never touch a wild bat [6].
- Bats do not intentionally fly into people’s hair.
- Most bats avoid human contact.
Are Bats Good for Vegetable Gardens?
Yes. Bats are especially helpful in vegetable gardens because they feed on many flying insects that damage crops.
They often hunt above vegetable gardens and around fruit trees at night, where flying insects are active. While they cannot eliminate every pest, they can become part of a healthy natural pest-control system.
Frequently Asked Questions About Bats in the Environment
Are bats dangerous to have around?
Bats generally try to avoid humans. They are nocturnal and spend their time eating insects, resting in their roosts, or hunting.
Like many wild animals, bats can carry diseases [7]. However, the risk is very low if you never touch them.
Do bats damage gardens?
No. Unlike many garden pests, bats do not eat leaves, flowers, stems, or roots.
Most bats either feed on insects, fruit, nectar, or pollen, making them beneficial rather than harmful to gardens.
What if I see a bat flying during the day?
A bat flying during the day may be looking for a new roost. It may also be escaping a predator or be sick or injured.
However, as mentioned, it’s best to avoid handling it. Contact local wildlife authorities if it appears injured or needs assistance.
Takeaway
For most gardens, bats are helpful visitors. They are among nature’s most valuable nighttime garden helpers.
Depending on the species, bats can help control insect pests, pollinate plants, disperse seeds, and support healthy ecosystems.
By creating a bat-friendly habitat, you can support local wildlife while helping reduce garden pests naturally.
