Every spring in Chattanooga, I start getting the same urgent calls:
“Bees are flying around the door where my kids play—what do I do?”
“There are bees flying around my porch—are they dangerous?”
“Should I spray these bees around my house?”

So far this Spring, I’ve already received multiple calls across the Chattanooga area about native bees, especially mason bees, carpenter bees, and leafcutter bees. It’s important to note this is not a list of ALL native bees, but these are a few I have received calls about in the past two weeks.

If you’re seeing bees around your home right now, here’s what you need to know before you take action.

Are Native Bees Dangerous?

Short answer: No. Native bees in Chattanooga are not aggressive and rarely sting.

Unlike honeybees, most native bees are solitary, which means:

• No hive to defend
• No colony to protect
• No reason to attack

In neighborhoods across Chattanooga—from urban areas to more wooded properties—these bees are simply nesting and gathering pollen.

Why Are Bees Active Around My House Right Now?

In Chattanooga’s climate, native bees emerge in early spring and remain active through early summer.

Right now, they are:

• Building nests
• Laying eggs
• Collecting pollen from local plants and trees

This activity is temporary, usually lasting just a few weeks.

Common Native Bees in Chattanooga

Mason Bees (Early Spring Pollinators)

If you’re seeing bees going in and out of small holes around your home, these are likely mason bees. Also, not all mason bees are native.

• Common in: Gardens, older wood structures, bee houses
• Active in Chattanooga: March–April
• Benefit: Excellent pollinators for fruit trees and early blooms

These bees are especially helpful for anyone growing food in the Chattanooga area.

Appearance: Mason bees are smaller than a honeybee. They have a darker or metallic blue or green appearance. They are most active in early Spring.

Nest: They use mud and clay in their nest construction. They nest in tunnels in pre-existing holes in wood or hollow stems. The live and work alone, rather than a colony with other bees.

Do They Sting? Females have stingers but males do not. They are not aggressive, however, and they have a mild temperament. The only live 4-6 weeks.

Carpenter Bees (Bees Drilling Holes into Wood)

If you’ve searched “bees drilling into wood in Chattanooga,” you’re likely seeing carpenter bees.

• Common in: Decks, fences, eaves, barns
• Active: Spring into early summer
• Behavior: Drill round holes to create nesting tunnels

Important for homeowners in Chattanooga:

• Male carpenter bees may hover—but cannot sting
• Damage is usually cosmetic unless unmanaged for years

Appearance: Carpenter bees are often mistaken for Bumblebees but Carpenter bees are shiny and Bumblebees have fuzzy bodies. Their size is around 0.75-1″. Females are all black but male have some yellow or orangish color.

Nest: Round 1/2″ diameter holes drilled into wood. You can often see the small bits of sawdust right under the hole. The tunnels are usually 6-10″ long. Common spots include eaves, railings, decks, and siding.

Do They Sting: Male bees have no stinger (the picture on the bottom right with the white spot is a male) but females do have a stinger-but don’t normally sting unless threatened (like everything lol). The Carpenter bees you are most likely to encounter are males. They are very protective of their nest and will intimidate people by getting very close to them. I have seen one get about a foot away from my little Shih Tzu’s face to try to get him to move and he just looked over at the bee and kept sitting in his spot-kinda what he does to me when I give him a command.

Leafcutter Bees (Bees Cutting Leaves in Your Garden)

If you’re noticing perfect circles cut from your plant leaves, you have leafcutter bees.

• Common in: Gardens and urban farms across Chattanooga
• Active: Late spring into summer
• Behavior: Use leaf pieces to build nests

They are some of the best pollinators for vegetable gardens.

Appearance: They are often small, metallic blue or black, and are frequently mistaken for flies. They are often active in early Spring.

Nest: Leafcutter bee nests are built inside small, pre-existing cavities like hollow stems, wood holes, or cracks. They line each chamber with neat, circular pieces of leaves, forming a series of sealed compartments—each holding pollen and a single egg. The nest looks like a tidy stack of green-lined “capsules” tucked inside a narrow tunnel.

Do They Sting? Leafcutter bees can sting, but it’s extremely rare. They are solitary bees with no hive to defend, so they have very little reason to use their stinger.

In most cases, they will only sting if they are directly handled or trapped (like inside clothing). Around gardens and homes, they are considered harmless and non-aggressive, and people can usually be very close to them without any issue.

Should You Spray Bees Around Your Home?

If you’re in Chattanooga and considering pest control for bees, here’s the truth:

My short answer is – NO! Spraying native bees removes some of your best natural pollinators.

These bees:

• Improve garden productivity
• Support local food growth and food output
• Help maintain healthy ecosystems

And most importantly—they will leave on their own.

Pesticides:

• They kill beneficial insects—not just “pests”
• They reduce pollination (which affects food)
• They contaminate soil and water
• They impact birds and other wildlife
• Some are linked to human health concerns

What to Do Instead (Chattanooga Homeowners)

If bees are in an inconvenient spot, here are better options:

• Wait 4–6 weeks for natural activity to end
• Seal holes in late summer or fall
• Paint or treat exposed wood surfaces
• Add a bee house to redirect nesting

These approaches are far more effective—and far less harmful—than spraying.

Why Native Bees Matter for Chattanooga’s Food System

Chattanooga has a growing network of:

• Backyard gardens
• Urban farms
• Community growing spaces

Native bees play a direct role in increasing food production in all of these spaces.

They:

• Pollinate fruits and vegetables
• Increase yields in small growing areas
• Support a more resilient local food system
