Hot Spots for Carpenter Ant Activity

Are carpenter ants a threat to New Jersey homes?

Unfortunately, yes. Carpenter ants are wood-destroying ants that are capable of damaging any wood within which they nest. Trees, sheds, window frames – it really doesn’t matter as long as it’s made from wood. As we dive into this article, we’ll touch briefly on carpenter ant identification and behavior, explain why they infest homes, and of course, discuss carpenter hot spots.

What carpenter ants look like

Carpenter ants are often described as large black ants and that’s true – with a caveat. Carpenter ants may be dark red or a combination of dark red and black as well.

As is the case with other types of ants in New Jersey, carpenter ants have six legs, and three distinct body parts. They also have antennae which look like handlebars--only those handlebars will appear backwards.

They don’t actually eat wood

Unlike termites that infest and consume wood and wood by-products, carpenter ants don’t actually eat wood. Instead, they excavate it in order to create tunnels and galleries in which to lay eggs. The resulting wood particles or fine sawdust that is created by their efforts is called frass and is pushed out of the tunnels so that they remain clean and clear of debris.

As we talk about hot spots for carpenter ants, we'll be discussing this frass quite a bit. Frass is one of the most important signs to look for to detect unwanted carpenter ant activity because these ants don't always leave noticeable damage for homeowners to see. Another important sign is the presence of the carpenter ants foraging for food in and around your home -sometimes alone and sometimes in larger groups.

How carpenter ants damage property

When carpenter ants infest, they chew galleries and tunnels in wood that can lead to structural issues and cascading damage. And, though carpenter ants prefer to chew on soft and decaying wood, they can damage sound hardwood as well.

Exterior hot spots for carpenter ants

Before carpenter ants infest your home, there’s a good chance you’ll find them in your yard – that is, if you know where to look for them outside. With that in mind, here are a few of the more common exterior hotspots for these destructive pests:

  • Hardwood trees with holes, knots, insect damage, etc.
  • Stumps & logs
  • Landscaping timbers
  • Rotting fence posts
  • Woodpiles

You might also notice carpenter ant activity in and around sheds and other outbuildings especially if there’s water damaged or moist wood present.

If you suspect carpenter ants are on your property, look for the presence of frass pouring out of a crack, or these large ants crawling around on the wood, especially at night.

If you have a deck, porch, patio, or exterior stairs, carpenter ants will likely attack these first because the wood of these structures are often less protected and often come into contact with the soil.

Carpenter ants prefer moist areas around a home because moist areas often have wet, rotting wood. If you have plants that get watered daily or shaded spots where rainwater moistens the soil for long periods of time, you may draw carpenter ants in. Search for frass coming out of foundation cracks or gaps in your exterior walls. Pay close attention to any areas that show signs of wood decay. Window and door frames are also a likely target for these ants as moisture often gets trapped in these areas.

As we mentioned above, wood is not a staple of the carpenter ant diet and so they must forage for food. Outside you might find them in the garden or among your ornamentals as they search for honeydew to feed on and the aphids that produce it.

Interior hot spots for carpenter ants

Carpenter ants typically set up a parent colony outside and satellite colonies indoors in or near wood that has been dampened or damaged by water/moisture. Common hotspots inside structures include:

  • Around sinks and tubs
  • Behind dishwashers
  • Around washers and dryers
  • Poorly sealed windows and/or door frames
  • Leaking roofs
  • Poorly ventilated crawlspaces
  • Damp basements
  • In wall voids
  • Under flooring
  • Near chimneys with poor flashing
  • Attic insulation

How to make your home and yard less appealing to these big ants

Since carpenter ants are drawn wood that has a high moisture content, it is imperative that you address any and all sources of water damaged or rotting wood. To that end we recommend:

  • Removing stumps, logs & other rotting wood
  • Stack firewood away from your home
  • Do not store construction materials next to your house
  • Replace old fence post that are split, damaged, or not treated
  • Minimize wood to soil contact whenever and wherever possible
  • Replace leaking appliances
  • Fix damage caused by water issues
  • Replace water damaged or damp wood
  • Repair any holes in the roof
  • Fix chimney flashing
  • Eliminate potential food sources
  • Address ventilation issues
  • Seal off any crack, gap, or opening from the foundation to the roof line
  • Trim back trees so that no part of them touches the house

What to do if you find carpenter ants inside or on your property

Carpenter ant activity, either indoors or outdoors, should never be ignored and instead considered a warning sign that your home is at risk for infestation. Whether you find one or several carpenter ants in or around your home, contact a licensed pest control professional for assistance.
