Questions
and Answers - woodworm treatment using chemicals - how do they work?Q.
WHAT IS A WOODWORM TREATMENT CHEMICAL?A.
Legally, in Europe, it is any chemical that has been approved by the Health
and Safety Executive (HSE) under the relevant European Directive and which carries
a current HSE Number. This means that it is considered to be both effective and
safe for use throughout Europe for treating wood boring insects. Click

Q.
WHICH TYPES OF CHEMICAL ARE APPROVED FOR USE IN THE UK? A.
They fall into three groups - growth
regulators, neuro toxins and biostats.
Q.
HOW DOES A WOODWORM TREATMENT CHEMICAL ACTUALLY WORK?
A.
1. Surface sealers and
hardeners. Not usually required to be registered as Pesticides.
They do not kill insects, but instead make the surface unsuitable for
egg laying. Female Anobium Punctatum are very fussy about the laying
surface. Ordinary paints, varnishes, waxes and sealants will prevent
egg laying.
2. Growth Regulators
are a type of Hormone which stop the grub from changing into an adult
beetle by preventing the development of its hard parts - the body case
and wings - so it cannot pupate and therefore cannot go on to mate and
produce more eggs.
3. Neuro toxins are
contact insecticides - they kill all insects, including spiders and
flies, on contact, by paralyzing them, so they suffocate. Permethrin
and Cypermethrin are neuro toxins.
4. Biostats only kill
insects that eat the treated material - in this case wood - and they
work by stopping the egg or grub from benefiting from its food, so that
it effectively starves.

Q.
WHAT LIMITS THESE WOODWORM CHEMICALS FROM BEING EFFECTIVE?A.
Reaching the grubs that are
deep inside the wood, doing the damage. Economically, chemical treatments can
only be applied to the accessible wood surfaces, so no matter how wonderful the
chemical it can only really act once the Adult beetle has emerged. It may act
by killing the adult or by killing the eggs, or both - but in all cases the chemicals
are effectively only there to 'break the egg laying cycle'. The adult common furniture
beetle only lives for about 3 weeks and does not eat any wood.
Q.
DO ALL WOODWORM TREATMENTS
KILL THE WOODWORM STRAIGHT AWAY?
A. No, only the Neuro
Toxins can do that - the others act on the eggs.
Q.
WHICH IS THE BEST WOODWORM TREATMENT? A.
Ideally, a treatment that can reach the grubs already inside the wood - but this
is not a chemical problem, this is a delivery problem. So, for normal surface
treatment only the best treatment would be one that remains permanently in the
wood, does not evaporate into the room, kills any eggs laid onto the wood, but
leaves other insects unharmed. Click

Q.
WHY ARE THERE FRESH BORE HOLES APPEARING, EVEN THOUGH I TREATED EVERYTHING MONTHS
AGO WITH AN INSECTICIDE? SHOULD I TREAT EVERYTHING AGAIN?
A. Because
the wood worm eggs bore into the wood and become grubs that live too
deep in the wood to be reached with a normal surface treatment. No -
don't treat again - it won't make any difference - common furniture
beetles may emerge for up to 5 years after treatment.
