Chip board floors are fine they are cheaper to buy and install but may last only 50 years and are less attractive Traditional floor boards are more attractive and can be left uncarpeted and might last years but are more expensive. As for the variety in quotes it depends how much you want to spend Mark Lorman Building Services. Greatly depending on the room use; under usual circumstances chipboard is fine but not as durable as timber and doesn't look so good, localised removal is also OK providing that all areas, once cleaned are treated with a proprietry fluid!

The living room has had damp, after taking up the floorboards, some of which had woodworm and also some rotten, I have found I need repair work doing to my ceiling and I have been told by a plasterer that in order to fix the cracks on my ceiling the I have pulled the laminate floor up in our new house to find very wet floorboards and sagging corners.

This is literally correct, but in practice living larvae are difficult to get at; being happy deep in the wood. It takes ages to carefully dissect wood to find them and afterwards the wood is destroyed, whether you are successful or not plywood is an exception, just peel away the layers and hey presto; exposed juicy larvae just fall out. An experienced specialist will access the situation and make a judgment based on a number of factors:.

He should then be able to provide a recommendation based on sensible methodology — it is not good practice to just recommend treatment whenever flight holes are found. If a surveyor recommends treatment or diagnoses woodworm and does not recommend treatment, ask why — he should have a reason for any recommendation. A roof void in Harrogate, with very obvious infestation by Common Furniture Beetle woodworm.

If you see something like this when you lift the carpet — call a specialist or treat it yourself if you have the confidence to do it. Publicity is often another word for rubbish — just read the Daily Mail or The Daily Star for example. It must be used only when needed and must be applied by trained and certified technicians, under the guidance of a qualified surveyor.

If that is done there is no risk to you. Technicians, using the stuff every day are at risk of course, so that is why they are togged up like astronauts. Cats and goldfish are exceptions — cats have died as a result of permethrin toxicosis when tolerant dog flea powder has been mistakenly applied to them.

Permethrin is very dangerous to aquatic life. This needs to be taken into consideration when it is used and especially when waste product is disposed of. It is safe once it is dried into the wood; cats are at risk during treatment and for a short time after though this is less to do with permethrin than cats — they also drop dead because they love drinking anti-freeze….. Modern treatments include a variety of chemicals, though for most infestations I recommend a Permethrin based insecticide.

Permethrin is a synthetic pyrethroid with very low mammalian toxicity cats excepted , It kills woodworm stone cold though. It is a contact insecticide so it will protect wood from re-infestation and will kill adults emerging from below during the flight season. Modern treatments like SoluGuard are come in handy soluble packaging to reduce waste. Boron products work well too, though these need to be ingested so are less effective on severe infestations; they have a dual action though, inhibiting fungal growth too.

I survey anywhere in the Yorkshire area, so you can always give me a call at Brick-Tie preservation if you need specific advice or a survey. Since treating, everything went quite but now there are signs of more dust in a few areas. Does this signify treatment failure or is it normal as I assume the larvae inside the wood will still develop and emerge?

Many thanks. Wykabor is a boron based fluid. It works superbly as a fungicide. Boron does have insecticidal properties and will protect wood from attack by woodworm. However, it works as a stomach poison and they need to ingest it to die. Anything else needs a contact insecticide. Permethrin based products kill on contact so they are active against all stages of the insect.

Eggs, larvae and adult beetles. Hi, Great blog, thanks for sharing your expertise. I think I may have read too many articles about CFB however and go from being reassured to paranoid in the same day! Nothing picked up on normal survey. The house has been empty for a few weeks now as he has been decorating.

Over the last month he noticed an odd beetle which we now realise is CFB, he caught one and the council identified it. In total he has seen around a dozen in 4 weeks, not noticed any frass although he has yet to take the carpets up to fully investigate, there are a few holes in the cellar timbers but they may be old.

The loft is inaccessible, very small space with thick insulation. Any advice would be appreciated. Sorry for the delay, I have a surveyor on holiday so I am working and theblog is not my full time job. However, the carpets need lifting and a thorough inspection carried out before you consider any treatment, professional or DIY.

It may be an isolated area, requiring disposal of the woood or topical treatment. I think you are great! Really humourous and fascinating blog. I had a cat who died from drinking antifreeze though — so didnt like that bit? My very elderly neighbours have an infestation of little black mites around all the window ledges.

The local council told her they were biscuit beetles but i am not so sure; they arent in the cupboards but hundreds along the wooden window frames. Do you think its possible they are biscuit beetles?? They the couple are approaching 90 and 93 years old and its a very big house. She is reluctant to pay someone as she is afraid of being conned or her cats being poisoned, and her husband is very sick at moment so its not really a priority for her.

Is there anything she can use safely herself or can you recommend someone in Tameside to have a look? Keep up the excellent work. Not many folk like you around, thank you! Thank you for the kind comments on my blog. It is easy to tell these beetles apart. You need a good magnifying glass or hand lens.

I would say that black beetles may be one of the forms of buscuit beetle but the common Stegobium is brown — just like common furniture beetle. I wonder if you are able to give some advice? We have at least two bedrooms where a faint munching sound can be heard at times seemingly within or above the plasterboard eaves. We live in rural Surrey and have only a very small loft space — the sounds seem to be in the eaves rather than the loft in any case.

No insects such as wasps seem to be coming and going. Do you have thoughts as to what might be causing the sounds and stains, please? I have no idea but not my field — almosty certanl;y not any kind of wood borer. Maybe birds, rodents, bats? Maybe call inthe local environmental health officer? I have a year old,10 bay barn with no history of chemical treatment for woodworm. The wood is very hard bellow 1 cm. I would like to treat affected areas but need to know which areas I have dealt with.

Do the boron treatments contain a lasting colourant please. Thank you for getting in touch. What you describe is very typical of CFB instestation. The heartwood under the sapwood outer layer will barely be touched. It is only vulnarable if the timbers get wet and start to decay. You say there is frass? Is this just visible when you knock the wood and poke it with a screwdriver? If so the infestation may be long gone.

Why not pick a patch and monitor that and see if any new flight holes appear? If they do, try a permethrin based insecticide, rathar ethan boron for this one. In the UK new EU regulations have just priced almost all manyfacturers out of the production of chemicals for timber treatment, so your options are limited.. Dear Dry Rot Many thanks for your excellent article. I wonder if you can help me with something that is nagging me. I have an infestation of woodworm in my ground floor timbers.

I noticed this around February this year. I was unable to treat the timbers until August. I can remember my old carpentry and joinery lecturer telling us over 30 years ago that there is something that can be placed near to the infestation and will kill the emerging adult beetles.

I have been unable to get hold of this or even find out its name. I desperately did not want further ww damage so I wondered if moth balls would do the trick. I put about 15 packets of moth balls under the floor at the end of April. I have just opened up the floor. One piece of wood had a number of exit holes with a number of dead, adult beetles right next to them. So it appears my cheap and nasty attempt to halt their progress has worked.

I had never heard of this before, have you? Do you know what the active chemical is that kills the ww? Also do you know when they emerge as adults?

I have read in spring but others say summer as well. When WW emerges you will often find dead adults around nfested timber. They will mate and lay eggs inthe old flightholes and then die.

One old treatment which works during the spring and summer flight season is Dichlorvos strips. These were marketed as fly killers but if placed in an infested confined space, like a sub-floor or loft, they did kill emerging adults.

However, the active ingrediant is quite nasty really, as it is a organophosphate chemical. Ministers took action in to suspend the sale of all insecticide products containing dichlorvos and then withdraw the approvals of non-agricultural insecticide products as a precautionary public health measure. Common furniture Beetle has a long flight season. May to September is the main window, but what with the warm weather and central heating this can broaden.

Thanks for this helpful article. We moved overseas for 8 years and this table was stored in our loft. When we have come to remove the furniture from the loft, the table now has hundreds of holes all in the surface small in nature like the common furniture beetle.

We are therefore very concerned that we have now infested our loft with woodworm! We are not actually living there at the moment and so are unable to just pop up and have a look but would be grateful for your advice as to whether you think that we should definitely get someone out to spray. You are right to be mildly concerned.

I would use the following method to monitor the roof over the next few summers…. Take a torch and enter the loft. Hold the torch so that the light beam is at a right angle to the wood — in effect shining across the wood. Check out the rafters and cieling joints.

If ther are no holes, make a note and carry out this inspectionevery year. If holes appear then treat it professionally via a PCA member. Alternativly have a PCA meber do these surveys for you.
