Carpenter Ants

What do carpenter ants look like?

Carpenter ants are the largest ants commonly found inside NorCal homes. Their size is often enough to help identify them. Worker ants range from ¼ to ½ inch long, while alates (winged ants) can be twice that size. Carpenter ants are typically a mix of dark red and black, though some are entirely black. If you get a close-up look, you’ll notice their elbowed antennae and a distinct node between the thorax and abdomen. 

How can I tell the difference between carpenter ants and termites?

Here’s how you can distinguish carpenter ants from Eastern subterranean termites:

• Color: Carpenter ants are dark-colored; termite workers are pale-colored.
• Waist: Carpenter ants have a pinched waist, while termites have no noticeable waist.
• Size: Carpenter ant workers start at ¼ inch, while termite workers are typically ⅛ inch long.
• Location: Termites prefer high-moisture areas and are rarely found in the open. Carpenter ants, on the other hand, are more adaptable and can be seen outdoors.
• Tunnels: Carpenter ants create smooth tunnels, while termites line theirs with mud.
• Wings: Flying carpenter ants have unequal wings, with longer forewings and a distinct cleft at the tip. Their wings are also darker and more veined. In contrast, Eastern subterranean termite swarmers have equal-sized wings that are rounded, translucent, and smooth.

Carpenter ants are far less destructive than termites, but their presence can still lead to significant damage if not addressed.

What do carpenter ants eat?

Although carpenter ants don’t eat wood, they feed on various food sources. Outdoors, they consume nectar and honeydew (a sugary substance produced by aphids). They also feed on insects—both dead and alive. Indoors, carpenter ants eat sweet foods like honey, syrup, sugar, and jams. 
‍

Do carpenter ants bite or pose health risks?

Carpenter ants can bite, but it’s unlikely. If they bite, the risk is minimal, typically resulting in a small red bump on the skin.

‍

Do carpenter ants cause structural damage?

Yes, carpenter ants can cause serious damage to your home. They tunnel through wood to create nesting galleries, which can weaken structural supports. While they prefer moist, damaged wood, they may also infest sound timber as their colonies grow. Left unchecked, carpenter ants can lead to serious damage over time.

‍

What attracts carpenter ants to my home?

Carpenter ants are attracted to properties that offer food, water, and suitable nesting sites. Conditions that make your home more appealing to these ants include:

• Water damaged wood
• High pest populations (especially aphids)
• Open trash receptacles
• Leaf and stick debris
• Logs, stumps, or stacked wood
• Poor irrigation and damaged sprinklers
• Overwatered vegetation and tall grass
• Weeds and other plant debris

Modifying your property to eliminate these attractants can help prevent infestations.

‍

Where do carpenter ants typically nest?

Carpenter ants prefer to nest in soft, decaying wood. Outdoors carpenter ants nest in fallen logs and branches, but once inside, they’ll target decaying timbers in your home. If your home has moisture-damaged wood, it’s more likely to attract carpenter ants.

‍

How do carpenter ants get into houses?

Carpenter ants can enter through any available gap, crack, or hole. They are especially drawn to rotted wood, so if your home has moisture issues, you’re more likely to find these ants.

‍

What are the signs of a carpenter ant infestation?

Some signs of a carpenter ant infestation are obvious, while others are more subtle. Look for the following:

• Large numbers of carpenter ants indoors.
• Winged ants inside or near your home.
• Shed wings on window sills or door thresholds.
• Frass (sawdust-like material) around gaps in structural wood or under punch holes.
• A hollow sound when tapping on solid wood.
• Visible holes in door frames or walls.

If you notice any of these signs, contact your Big Time Pest Control team for an inspection.
