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.

Hello,
I am writing b/c I am at a loss. I live in south Florida and we of course have ants. Inside my home I have been finding in the corners dirt mounds that come out of the wall. I will clean this up and sometimes I find an ant or two in the dirt - I spray (several times) in the area I find the dirt and they seem to go away (temporarily). The past few weeks I have been find ants w/ wings around areas that I have a lamp or light and they seem to be coming from the area that I found the dirt. My husband says there are not termites b/c they have a 3 part body (head, torso, and back) but I want to make sure. I am willing to call an exterminator if needed but I need the advice of a professional to get the approval form my Husband to call the exterminator. Please help!! Thanks!!

My ants live in or near my huge Redbud tree. They are ants and not termites. I want to save the tree. They are red and black ants. The tree is old and has rot that I am having cut away soon. I live in North Central Texas. So far I have treated the tree with Bayer pour on insecticide applied at the base, then you add water. Lasts for up to a year. I treated last year about this same time (May-June). Help me save my beautiful redbud, please. Of what I've seen, carpenter ants are black...what kind might these be that are destroying my redbud?

Thanks for all the help you may give,

Cindy

Hello.
We're coming up to our first year in our house and we've discovered carpenter ants. The big, black ones.

First up .. we're in a heavily treed area, with lots of dead trees on the ground. The closest "pile" would be about 20' from the house.

We first noticed a couple of them on the main floor .. over the past few days we've noticed quite a few in the unfinished basement .. maybe 25-50 of them. Our water treatment and sump pump is in the basement. They seem to be entering the basement in the ceiling joist .. one area only. After looking around the house I cannot find any trails leading into the bush.

However, I noticed the little buggers coming in and out of the garage door pillars. I noticed some loose foundation material in the immediate area and they are entering from inside and outside of the garage door area.

I'm assuming the ones entering from the garage are winding their way inside my walls to the basement. It is about a 15-20 trip for them.

How do I treat the ones entering the garage .. and also the ones entering my basement. We're on a well and septic so I'm concerned about that. Thank you for your time.

Mike

p.s. I can post links to pictures if that would help you or others with similar problems.

I moved into my home over the winter and last weekend all of a sudden started noticing carpenter ants. I have never seen them in the kitchen looking for food, only on the second floor in the bedrooms. I followed them up into the attic and they seem to be crawling down the outside of the "stink pipe" from the bathroom down into the attic floor. I sprayed this area heavily with a jug of insect killer I bought at Wal-Mart. Will this kill the ones in the nest which I assume is either in the walls somewhere or in the attic floor? Do the ants live in sheetrock? I noticed fine powder, but it looked white not like wood. It is strange to go from Zero ants to a hundred in one day? The night I started seeing them was last Saturday which was the 1st hot / humid day we have had this year. I did spray the perimeter of the house about 6 weeks ago and thought I would prevent this problem. Any insight or advice is appreciated. Thanks!

My porch roof has developed a serious leak, with water from rain or snow dripping through the ceiling onto the porch floor. I had it patched when this happened some years ago, but the problem is back. The whole roof needs to be reshingled anyway. Recently I've noticed brown dirt/sawdust-like piles appearing below spots where the ceiling boards have warped, creating gaps. I haven't seen any insects in the vicinity of the gaps. Is this likely to be residue from insect damage or just damage from the water?

Do you know of an ant species which, when swarming, gives off an odour like rotting oranges? (I know there is one, because we've got them!)

Hi Exterminator,

Today, in mid-July, we found a pile of probably 50 winged carpenter ants laying squarly in the middle of the room on the concrete basement floor. They were all barely moving or completely still. My husband vacuumed them up with a dust buster.

Does this mean we have a nest IN our house, or could they have just flown in through a hole from outside? (We found a small hole afterwards that we have since filled).

Thank you for any help!

I have a hanging lamp that hangs from my ceiling. Just below it I find dirt sprinkled in the bottom of the light fixture as well as all over what ever I sit just below where it hangs. I tried taping up the base of the lamp on the ceiling and I noticed a bunch of winged nats caught up in the tape. Could you give me an idea of what type of insect this sounds to be and how to get rid of it. Thank you! Doreen

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 .

I am trying to identify the culprit that is leaving behind its boring mess. I have a good pic- can i send it to you?
I have seen ants as well as termites outside but this insect is getting in and i think, eating our hardwood floor in one corner. Its not piled in a cone but it sounds like 'frass'. or at least it sure is a pain in the frass.. since it comes back all the time after cleaning and i have small children.
where can i send a pic? Thanks!

Hi,
I am currently in contract for a home that had termites and possibly some carpenter ant frass. We insisted on termite remediation as part of our contract but was told at the time (It was almost spring) that it didn't look like an ant problem and that the termite baits should help with ants too. . .Now it's summer (house is still a few months from closing due to problems with seller) and carpenter ants are swarming in outside tree stumps. The termite baits have high acceptance but no further termite activity was found. There is an area of concern to me in the house. Sliding doors leading to the deck are misaligned allowing rain to come in. Hard wood floors next to the doors are warped up. I am concerned ants may be in the header below. What do you think? Due to sellers problems, I may be able to get out of contract. With this many visible ants outdoors, potentially could the house be infested too?? We do not have the funds to do extensive structural repairs on the home.
Thanks for any advice you may have!!

Well i will post my question on here and see if i can get some help with my problem.
Recently i had a severe leak around my air conditioner and although i tried to chalk it it would still leak so I took down one panel around it in hopes to see where the leak was. When i took down the paneling it was full of ant eggs and ants..red in color, some bigger with wings. I took down some molre paneling and more ants..so i call pest control and they sprayed the wall and also put some powder around. This took care of that side but now i have to reinsulated and sheet rock the whole wall. I went up on a ladder and was going to chalk the siding that was put on (believe me it was a crappy job too where i could see the insulation that was put up and the space in between)now i have found ants on the other wall and want to get rid of them before i put up new insulation and walls...i have thought about drilling some holes in the existing paneling but have no idea what to put in the holes to kill off these ants so they dont go from wall to wall and i have to redo all the work again...please help
