Moths in Pianos

How to Deal With a Moth Infestation in Your Piano

We get quite a few enquiries about the risk of moths damaging pianos, and in particular the felt hammers – piano hammers are made of felt wrapped around wood and are prone to moth damage because felt is made from matted and condensed woollen fibres, a great food source for many varieties of moth, including carpet moths, clothes moths and house moths.

The other attractiveness for moths in pianos is that if they can gain access, the inside of a piano is a near perfect environment with little light, being undisturbed and with an appropriate food source. Replacing the piano hammers before the end of their normal life, and risking a potential infestation in the house beyond the piano, particularly for carpets and rugs, can be a very expensive business. We have customers who have been quoted hundreds of pounds by professional pest controllers to treat their pianos for a moth infestation – you don’t need to spend huge sums of money to quickly and effectively deal with the problem!

For control, if a moth infestation is already present, and possibly more widespread in the room in which the piano is sited, then starting your treatment with a Fumer, with the piano open, should have a significant impact on the adult moth and larvae population. If the problem is localised and control is required in the piano only, use a water-based pyrethrin spray such as the Fortefog Natural Protector Aerosol and close the piano immediately after spraying to contain the power of the spray in the piano itself. Avoid using oil-based aerosol sprays which could harm the piano mechanism leaving residue behind after application. The pyrethrin in the Fortefog spray is a naturally extracted pesticide.

To reinforce the initial treatment and protect against further incursion by moths in to your piano, we suggest either using cedar anti-moth products as a natural solution or the fragrance free moth killer strips. We would recommend the killer strips initially and the cedar as a longer term deterrent. Please remember to replace, or in the case of cedar products, refresh, your deterrent products every six months. Cedar can be refreshed by lightly sanding and the application of cedar oil.

Do be sure to check your carpets thoroughly and in particular, under furniture and along skirting boards – the infestation is unlikely to be exclusively limited to your piano.
