Sadly I've discovered signs of woodworm in some of the workshop
timbers. I'm told the main roof timbers were treated a few years ago but
not window frames and other less important woodwork.
Do any of you have experience in treating against woodworm in already
effected timber?
Which chemical is most effective?
Life expectancy of the treatment?

The sheds sell treatments for you to dip/ brush/ spray. Proper
mask, safety visor, gloves etc, follow destructions, job
done.

Active woodworm with little pipes odf wood dust at the holes or just
holes woodworm in the past?

Got a few floor joists above my head in our victorian shop that were
affected. Chipped out the soft/powdered wood and liberally soaked
everything in Wickes' finest WW treatment.
Not had any issues since.

Also have occasional outbreaks in out 18th C. listed "project" cottage
in Brixham in the timbers above windows amongst other places.
At the time we had an insulin dependent dog and I found injecting WW
treatment into the exit/flight holes got the stuff right into the
critical areas that surface brushing would never reach.

Re-apply each year to areas that have evidence of the current years
woodworm activity should keep things in check. Don't recall seeing any
fresh activity in previously treated timber.

a supply of 14 redundant insulin syringes and needles every week, hence
the discovery that they're perfect for injecting woodworm killer into
the holes although high VOC woodworm treatment means each syringe
doesn't last very long before it seizes up.
Insulin syringes with needles are readily available on-line for not too
much but there might be something made specifically for the job that can
cope better with chemicals.

Surprisingly long. Our loft was done before we moved in and the wooden
surfaces are still lethal to flying insects nearly 25 years later.

The sheds sell treatments for you to dip/ brush/ spray. Proper
mask, safety visor, gloves etc, follow destructions, job
done.

There is more than one formulation about. ISTR The water based one is
synthetic pyrrethroid and seems to work well as a spray - which is good
for getting into awkward corners. It smells a bit.

The other is solvent based, smells terrible and flammable so I wouldn't
fancy spraying it, but it is OK when used with a brush. I think it is
also capable of killing stopping various rots as well as woodworm.

The most effective chemicals are only really available to commercial
operators with the right PPE including a full face respirator. That is
what our loft was done with stuff by Protim (if they are still going).

ISTR they got the apprentice to go in there and do it.

is this active or historic worm? In the latter case it should not be treated - and most is historic worm.

Victorian houses were (either sometimes or always) built partly with green timber, which was wet & thus vulnerable to insects for the first couple of years.

Active in some widow frames and other less critical timbers but

Have a look at boron-based woodworm treatments.

Water-soluble, so won't penetrate paint/varnish, and washes off outdoors.
Effective against rot as well. Life expectancy is indefinite, as it's a salt. It
also won't evaporate or outgas.

Apply with brush, syringe, sprayer, ...

My house has had a bit of woodworm (mainly historic). I treated one or
two spots that were possibly current with Rentokil woodworm treatment.

If I understand things correctly, woodworm are flying insects, so I
reckoned that if you can intercept them with a slow-release fly-killer
(see later) on their way in, they won't get a chance to stick their
ovipositors into your woodwork to lay their eggs - so you won't get the
grubs that tunnel their way out, leaving the tell-tale holes.

My house also seems to be a highly-desirable residence for wasps, so
every spring and early summer I have to take steps to deter them from
making a wasp-line for my loft, garage or garden sheds. I used to
install a few of those Vapona fly killer things (with adjustable
shutters so you could control the vapour release rate) - but apparently
the EU decided that as well as flies and wasps, they could kill people
too. These days I have to improvise by spraying an aerosol into an
opened-out newspaper, then folding the newspaper up to slow down the
rate that the fumes leak out. Although I've been targeting wasps (who
usually fly a mile if they only smell fly/waspkiller), neither have I
seen any sign of new woodworm holes.

Barratine still sell solvent-base woodworm killer, but I suspect
the sheds will only sell water-based rubbish now.


I replaced some woodwormy joists when doing my garage roof recently.

These were 1976 era and really heavy hard imperial sized 8x2's.

I used my cicular saw to cut through the badly affected bits and
couldn't see much internal damage at all.

Some people nail lathes of cedar wood or other timber that
the flies like the smell of, over the normal timbers and the
eggs are laid on those.

Remove them in NOvember/December and burn them, then replace
with fresh lathes.

But they are beetles that do fly at times.

Common garden sprayer and you are fine.

Borate-based treatments are water-soluble salts -- nothing to do with the EU.

Borates are nice because they stay put. A lot of the organic toxins evaporate
slowly, and some later turned out to have unpleasant side effects on humans.

Victorian houses were (either sometimes or always) built partly with green timber, which was wet & thus vulnerable to insects for the first couple of years.

Also, woodworm can't bore into timber in heated areas of the house as
the moisture content is too low. To be a current infection, timber
would need to be in an unheated area of the house, or exposed to damp
(which will cause rot in any case).
