Post by Martin BrownPost by Simon ParkerPost by Roger HayterI don't have a an opinion, but if they are not vermin then a question about
invertebrate infestations needs to be added to pre-sale inquiry forms. I would
certainly want to know about previous moth, cockroach or Pharoah's Ant
infestations if I was buying a house. And the questions all need wording like
the neighbour dispute question to include previous problems even if the seller
honestly and reasonably believes they have cured the problem.
I know without needing to look it up that cockroaches are definitely
considered vermin and would need to be included when answering a
question about vermin.
Pharoh ants are another potential gotcha with modern central heating
larger properties with ducted air CH can end up with impossible to
eradicate number of them lurking in dark corners.

Why would sealing up the place, (as far as practicable), maintaining a
temperature between 20°C and 25°C, and then filling it with sulphuryl
fluoride at a concentration of 21.3 (+/- 1.3) g/m3 for 48 hours not be
effective? (Genuine question having asked a man that knows about these
things.)
Post by Martin BrownI'm slightly concerned about the wool eco-insulation and plague of moths
issue as our VH has wool based loft insulation.
Probably worth checking if the woollen insulation used was treated with
borax prior to being installed.
Random related fact: Be careful when using pallets for DIY construction
projects in the garden. Pallets labelled "HT" have been heat treated
making the timber more durable and less prone to rot.
However, pallets labelled "MB" have been treated with methyl bromide
which will leach out over time and so they should not be used in
projects involving flora and fauna, (e.g. constructing a DIY compost heap).
Post by Martin BrownPost by Simon ParkerAs I've said in a parallel post, the phrase I've seen refers to
"pests" rather than "vermin" and it is clear that moths, cockroaches,
ants and indeed any kind of infestation would be covered under "pests"
even if not technically "vermin"
IMO, the question and guidance on Japanese Knotweed is perhaps the
most stringent on the TA6 form.
Is the property affected by Japanese knotweed? Yes | No | Not known
"If you are unsure that Japanese knotweed exists above or below ground
or whether it has previously been managed on the property, please
indicate this as 'Not known'. If 'No' is chosen as an answer, the
seller must be certain that no rhizome (root) is present in the ground
of the property, or within 3 metres of the property boundary even if
there are no visible signs above ground."
Japanese Knotweed gets a bit of a bad press. It *is* invasive and
vigorous but it was grown as an ornamental by the Victorians and I
played in a half derelict Victorian garden full of it as a child.
As this is a legal newsgroup, I will respectfully remind you that
Japanese Knotweed is listed in Schedule 9 of the Wildlife and
Countryside Act 1981 is is subject to Section 14 of the Act which makes
it an offence to plant or cause it to grow in the wild.
It is also classified as controlled waste by the Environmental
Protection Act 1990 which means the disposal thereof is tightly governed
to licensed facilities only.
You may consider that "a bit of a bad press". Unsurprisingly, I am
inclined to look at the matter differently. :-)
Post by Martin BrownVictorian concrete foundations could resist its runners well enough. It
is the cheap and nasty foundations on modern build housing that yields
and also to bamboo runners (which will become much more of a problem as
the climate warms). They really can be *very* penetrating.

I have volunteered in the past that a family member works in the
horticulture industry. Earlier this year, their company undertook a job
on a garden which had been landscaped by a person or persons unknown, no
doubt at considerable cost to the owner of the property at the time.
Included in the garden were two patches of "black bamboo" (Phyllostachys
nigra) measuring approximately 2.5metres x 1metre each.
My relative's services were engaged because, contrary to what was
specified at the time of installation, no physical containment barriers
had been installed and the bamboo had started to spread under a nearby
patch of (no doubt equally expensive) artificial 'grass'.
The initial job involved lifting the 'grass', removing all running
rhizomes and then replacing the 'grass'. The cost for this could be
considered reasonable, (about 1 man day's labour).
A follow-up job, involved completely excavating the area, and removing
both sets of bamboo, installing physical containment barriers and then
replanting the bamboo. The cost for this work ran into four figures. :-(
Also, it isn't just damage to foundations. If one's bamboo spreads into
a neighbouring property, it is considered a trespass and one becomes
liable both for the trespass and for the damage arising therefrom.
Which is not limited only to foundations but would include fences,
paths, border shrubs and plants, etc.
My relative has an employee that produces CPR Part 35 Compliant Expert
Witness Reports (aka CPR 35 Compliant Reports) on bamboo as part of his
day job. No shortage of this type of work, apparently. :-(
Post by Martin BrownPost by Simon ParkerAnswering "No" requires you to be "certain that no rhizome is present
in the ground of the property or within three metres of the property
boundary". Are you going to dig up your entire garden and ask your
surrounding neighbours to do the same within 3 metres of the boundary
to enable you to answer "No" or are you just going to tick "Not known"?
I know where there are places with the stuff growing (and under official
management) well away from any modern buildings. It is very tenacious
and has not been killed by nearly 5 years of regular annual treatment.
Equally the patch has not got any bigger.
I am told by a "man in the know", that an injection of neat, (i.e.
undiluted), 480 g/L glyphosate into the stem using a hypodermic syringe
will pretty much see it off almost instantly (21 days or so). (Easier
and better to use a stem injection kit if one has a lot to treat.)
However, it would be a clear breach of the relevant legislation for a
professional to do this as they would be exceeding the maximum stated
dosage rate. Similarly, it would be a breach for somebody that wasn't a
qualified professional to purchase the herbicide required. But, if one
were to find some Glyphosate 480 in one's shed, purchased a stem
injection kit and DIY treated it in this manner, I am reliably told that
the Japanese Knotweed will be gone in a few treatments with no laws
having been broken, to the best of my knowledge. :-)
Post by Martin BrownPost by Simon ParkerThe revised guidance, (issued in February 2020), makes the question
all but useless from the buyer's point of view so is less useful to
them than it was before the guidance was issued which seems to be a
waste of everyone's time.
It is only really a threat to modern build homes with weak foundations
(or very old ones with no foundations).
And if it comes up under one's path at the end of the garden, well away
from the house, having spread under the fence from next door, what then?
(See above regarding trespass and legal liability for damage arising
therefrom).
