Carpenter Ants

CARPENTER ANT IDENTIFICATION

Common carpenter ants are one of the largest common household ants. Usually dark brown or black, they typically measure up to 3/8 inch in length, but winged reproductive carpenter ants may grow to nearly double that size. Like all ants, they have a distinct head, thorax (the chest-like middle section) and abdomen. A single, hump-like node at their waist helps distinguish them from other ants, which can have one or two nodes, and node-less insects such as wasps.

Homeowners often confuse carpenter ants with termites, especially during mating times when winged ants appear in swarms. Both these pests damage wood, but they look very different. These key features help tell them apart:

• Antennae – Ants have jointed antennae; termite antennae are straight.
• Waistlines – Ant waists are pinched and defined; termites look like cigars.
• Wing length – Ant wing pairs are different lengths; termite wings are equal in length.
• Color – Carpenter ants are usually dark; termites are typically lighter brown.

SIGNS OF CARPENTER ANTS

Carpenter ants nest in moist, decaying wood. Unlike termites, they don't eat the wood they excavate. If you see sawdust and insect debris piled below moisture-damaged wood, you have a potential problem. Open the wall and peek inside. Carpenter ant galleries are smooth and debris-free. Termite galleries are rough and lined with excrement.

Swarms of winged carpenter ants inside your home are a significant sign of a major infestation. This often occurs in spring, when ants mate. While a few winged ants shouldn't worry you, large numbers point to long-term infestations and significant structural damage.

HOW TO CONTROL CARPENTER ANTS

One of the country's leading wood-damaging pests, carpenter ants work slower than termites but their damage is severe over time. Effective control requires killing ants you can't see as well as those you can. Amdro® brand offers several options to kill carpenter ants and reclaim your home:

• Amdro Quick Kill® Indoor/Outdoor Carpenter Bee, Ant & Termite Killer, available in ready-to-use  and concentrate formulas, kills carpenter ants and keeps protecting against new infestations for up to three months outdoors and 12 months inside.
• Amdro Quick Kill Indoor/Outdoor Carpenter Bee, Ant & Termite Killer Foam simplifies treating hard-to reach areas. Complete with a straw for precision application, this foam expands when sprayed to kill wood-damaging pests where they live.
• Amdro Ant Block Home Perimeter Ant Bait targets carpenter ants as they forage for moisture and food. Ants carry bait back to their colony, so the whole colony dies.

CARPENTER ANT TIPS
