Carpenter Ant Damage


Summary: Is it a carpenter ant damage or termite damage? Both dig into wood. Both can ruin your day. This article will give you some easy ways to identify what's eating your wood.

Pest control experts are often called upon to identify the cause of apparent pest damages to property. Half the time the pest has left the scene of the crime and the only evidence remaining is the damage done. However, a knowledgeable professional should be able to determine the cause simply by examining the damaged wood.

Let's look at how carpenter ants attack wood. True to their name, carpenter ants will tunnel into any wood that suits their purpose, but they don't actually eat the wood. They only work with the wood, creating tunnels and galleries in which they raise their young. The damage may occur indoors or outdoors.

To the layperson carpenter ants and termites look alike and behave in the same way. They both cause damage to wood. However, there is an easy way to tell the two apart. If carpenter ants are the culprits the damaged wood will be free of mud and wood particles and the galleries will be smooth. If the damaged is ragged, thin layers of riddled wood, mostly packed with drying dirt, you can assume you have found termite damage.

Here are some more tips to identify if carpenter ants have damaged your trees:

• Look for frass. This is a pile comprised of soil, dead insects and wood shavings that resemble sawdust. Frass is usually in a small pile shaped like a cone. Similar to your children leaving piles of clothes in their bedrooms, carpenter ants leave piles of frass by their nests. However, the tunnels that carpenter ants create are usually hollow and smooth, in order to give the ants plenty of room to crawl. Their tunnels are extremely clean and lack frass.

Though carpenter ants can cause damage to healthy trees, moist wood is especially susceptible to damage from these ants. Rotting tree trunks, stumps, or roots are often infested with carpenter ants. Healthier, more solid wood is harder for the ants to chew through with their mandibles (commonly known as jaws).

Trees attacked by carpenter ants are usually under stress. The tree is most likely decaying and carpenter ants are just cashing in on the situation. The tree's primary problem is moisture or decay. The carpenter ants are not the cause of the tree's decline.

Carpenter ants build two types of colonies; parent and satellite. The parent colony is the main colony and must be in an area of moist

wood. This colony will most likely be outdoors in trees, stumps or firewood. Satellite colonies can survive indoors. While foraging for food, carpenter ants can find their way into your home and get cozy and comfortable. Again, moisture is the key to their survival. Discovery and elimination of the moisture is the sure-fire way to fight a carpenter ant infestation.

Dust formulations of insecticide are an effective way of treating carpenter ants outdoors. Make sure to use an insecticide that is specifically labeled for carpenter ants and for safe use on trees. Be aware that carpenter ant infestations can be reoccurring, so you may have to reapply the insecticide every few months or so. Unfortunately, this may be the only efficient solution to getting rid of carpenter ants outdoors. If the tree is in full decline, removal of the tree and stump may be your final option.

Remember, the carpenter ants are Nature's way of decomposing dead wood. If the ants are doing their job and not invading your home, leave them do their work.

Hi,

It's been about 1 1/2 weeks now that we have been having ants in our home. It started on the Master bathroom floor, Then we found one of our night stands full of them in 2 drawers all over our clothes. They are small little black ants. We sprayed and killed these. Then a few days later they were in the kitchen coming down the side of the wall to towards the sink. And then they were on the opposite counter, master closet, and office next to master bedroom, etc. About 5 different locations all on the same side of the house though. My husband sprayed out side and we've also been spraying inside. The weather where I'm living has been record breaking tripple digits most days here in TX. Please help, any advise would be greatly apprecaited. We are going to spay the entire house this weekend and check the attic. By the way, the ones in the kitchen didn't go to our food. We also have seen them in the yard coming out the ground and on the side walk near our house. As I mentioned they are small little black ants. Ocassionaly there will be a larger sized one. Thanks again. Hopefully we will not need to call anyone out and will be able to fix this ourselves. We have never had any problems in the 5 years living in this home which we built .

Last year I had carpenter ants inside my home. Winged ants and worker ants. I contracted Terminix to take care of the problem and it became very costly. Just yesterday I noticed some winged carpenter ants in the large tree in my backyard. Do winged ants signify that the ants have been present for years? If I cut down the tree will the ants just come towards the house? I would much rather have the tree removed then consistently paying for insect control. Is it possible to save the tree and get rid of these carpenter ants? What are my best cost effective, headache free options? I want to be pro-active before the inside of my house is taken over by the pests again.

Your help is appreciated.
Thank you.

Carpenter ants only attack dead or dying trees. It may be too late to save your tree. The winged ants are the reproductives that swarm out each year from the established ant colony. They try to mate and establish new ant colonies. Taking the tree down does not mean your house will be attacked by carpenter ants, but you need to be sure your gutters are not backed up creating soften wood. They will attack wood that is wet and soft. You need to speak to a tree expert to see if the tree can be saved.

We have several areas where the small ants have been eating Styrofoam and leaving piles of dust in the general area...We also have another area where they have started to eat the fiberglass insulation and leaving yellow dust in a 6 foot area from the soffits on our back deck? They are less than a quarter inch and black in color. Any ideas all to how to manage these little guys and how or what stage is my next level of attach...should I bring out the big boys and eliminate the million plus army? Thanks Rick

The key to control is identification. First, determine if, in fact, your ants are carpenter ants. If they are you will need to monitor their night activity to see if you can determine where they are nesting. They move in trails and you might be able to locate and treat the nest to stop their invasion.

I noticed a buzzing noise in rhe living room in one of the outside walls. When I went downstairs to the basement I found a sand colored powdered dust under the area where the noise was noticed.What can this be? I thought possibly electrical until I saw the pile of dust.
Thank you,
Barbara
