Popular Post bbabythai Posted August 5, 2021 Popular Post Share Posted August 5, 2021 The wife and I just looked at an old house for sale. I got in under the house and noticed this huge ant mound. I suspect termites but have no idea to be honest. If you have experience with this could you please advise. thanks 1 1 3 Link to comment Share on other sites More sharing options...

Popular Post KarenBravo Posted August 5, 2021 Popular Post Share Posted August 5, 2021 (edited) Yes.....it's a termite mound. Dig down to find the Royal Chamber and then kill the queen. The chamber has a few small openings for the workers to get in. They are also made of a darker soil and very smooth. If you don't somehow kill the queen, they'll be back. Have tried chemicals which are a bit hit and miss. Killing the queen is 100% effective. Edited August 5, 2021 by KarenBravo 8 1 Link to comment Share on other sites More sharing options...
bbko Posted August 5, 2021 Share Posted August 5, 2021 Tell the seller you have no intention of buying unless the price is dropped, and watch out for other hidden pitfalls. 2 Link to comment Share on other sites More sharing options...
Popular Post Etaoin Shrdlu Posted August 5, 2021 Popular Post Share Posted August 5, 2021 Termites. There will be tubes leading from he nest into the house where the termites have been feasting on the wood inside. Termites hollow out wooden moldings, floors and fittings leaving a thin veneer that looks normal but is unsound. If you are interested in buying the house, make sure an expert checks for termite damage first. Usually the main termite mound is located underground somewhere near the house, but those mounds are so large the main nest might be in there somewhere. Professional exterminators sometimes use bait that is treated with a chemical that interferes with the termites' ability to molt. The bait works slowly and it takes about two months or so for it to work. The colony collapses after the queen is fed with sufficient bait and dies. This method works quite well. 9 2 Link to comment Share on other sites More sharing options...
steven100 Posted August 5, 2021 Share Posted August 5, 2021 if it's cheap enough and you can witness no infestation inside, however this is difficult unless you can remove architraves and skirting boards, which i'm sure the sellers won't like or even agree to. you need a chisel and a claw hammer. 2 Link to comment Share on other sites More sharing options...

bbabythai Posted August 5, 2021 Author Share Posted August 5, 2021 Also, I obviously know that termites decimate wood in a house. But this house is a concrete structure and has brick/ cement footings. My question is.... can these termites stuff up the structure of this house?. Its got a tiled roof (old style ceramic tiles) and presumably these are supported by either wooden or concrete beams. I suppose I have to get inside the ceiling. Any opinions are appreciated 1 Link to comment Share on other sites More sharing options...

Any opinions are appreciated We have them around, but have concrete floor, steel beams in the roof, so if you find same, it's ok as far as I am concerned, as I am also told that, the mounds could be used as a base as they travel far underground to eat and return ?

Popular Post jojothai Posted August 5, 2021 Popular Post Share Posted August 5, 2021 (edited) Termites do not only attach wood. They also chew out grout and weak concrete. You have to look for the telltale signs of eating into wood and for Grout (loose or missing) On the second picture below, the termites had chewed into the grout joints in the shower floor. Its been cleaned up but you can see the grout is missing. Edited August 5, 2021 by jojothai 3 Link to comment Share on other sites More sharing options...
jojothai Posted August 5, 2021 Share Posted August 5, 2021 Looking at your photo again, the brick joints on your photo look reasonably good. But could have been cleaned and patched up since the termites had originally been there. If the termites were still around I would have thought here should have been some evidence there.

That's what I used to think until I saw what they can do to grout joints in tiles and some items that had a grouted or cement surround. 2 Link to comment Share on other sites More sharing options...

THanks for all the comments. I also took photos of these cracks which go around the house on the outside on the same side where that termite nest is. I dont know if its them causing this. But theres also cracks high up in one of the photos. What do you think? Link to comment Share on other sites More sharing options...

Yes, they also chew into into them which will open them up a bit more That's not so good in reinforced concrete where there may be more chance of it leading to corrosion if the reinforcing is near the surface. I cannot see much evidence of corrosion on the pictures, except in the corner on photo 3. The dark patch. 1 Link to comment Share on other sites More sharing options...

But theres also cracks high up in one of the photos. What do you think? The photos do not look like anything to do with termites. I think the photos are all for concrete. But the last two may have a rendered surface Photo 1 looks like it may have originally been a defective joint that was likely cleaned out and repaired. Assuming it is concrete then likely it was a horizontal joint. Cracks do not usually form so clearly in a line. You can see the repair by the difference in the surface. The repair mortar area has cracked and needs making good. It does not look very good but could be superficial. Clean out a bit and it should be possible to judge. Photo 2 and 3 a bit unusual. Look like shrinkage cracks, but nearly along lines. Do not look like formed joints. More likely joints in the layering of the concrete. Poor compaction. Cracks form along the weak areas at the surface. The dark area looks like it could be a small area of corrosion that needs repairing. Photo 4 look like simple very small shrinkage cracks due to poor curing and protection. Photo 5 definitely looks like its where there is a horizontal joint. The cracks formed in the surface look likely to be large enough for capillary action from water on the surface to cause corrosion. They should be cleaned out and made good. Possibly a small horizontal notched cut out could be made to clear the bad area and make good. Link to comment Share on other sites More sharing options...

Popular Post couchpotato Posted August 5, 2021 Popular Post Share Posted August 5, 2021 Lots of advice here, but you have a huge amount of work to do on the house, with the cracking and termite damage (mostly unseen). And from your initial questions you don't know much about construction or house builds, so unless you get the house for a fantastically cheap price, then my suggestion is don't buy, because these type of problems can cause tears.???? 4 Link to comment Share on other sites More sharing options...

jojothai Posted August 6, 2021 Share Posted August 6, 2021 3 hours ago, KarenBravo said: Termites don't eat, or chew concrete. Their jaws are just not strong enough (like yours). Water penetrates concrete without having Jaws. It does so through cracks and joints and can degrade the concrete in these places. Yes, termites do not eat cement based materials, but they chew. As stated in the articles Solid Concrete no, but also note. "Poured concrete foundations are most resistant to termite attacks, but only if walls have no visible cracks" Cracks get degraded and porous areas at cracks / joints are not solid. I showed a picture of a termite that had chewed through grout. How do you explain that? They had chewed through most all the grout between tiles in the shower floor. The grout cement particles were all heaped around the joints. That was not the worst. They had chewed out the cement fill around pipes in the walls. Grout is made of cement and that is what is used in concrete as the binder. The grout was solid, but because in a area that gets wet it can make it more porous and easier to chew. At concrete cracks or joints, you can expect loose and degraded areas. Water adds to the problem. Termites will penetrate cracks or joints as best they can, From what I have seen they can chew through degraded cement or porous areas just like the grout on the picture. 1 Link to comment Share on other sites More sharing options...
