 Moth Damage
Author: Mike12.10.26

I've got some old classics that have moth damage to the pads. These are all professional instruments, 3 of them, and I'm heartsick! How can I get rid of the moths, eggs, larve, etc so it dosent happen again? Will moth balls in the cases do the trick?
I was thinking of temporarily storing the clarinet sections in sealed plastic bags and putting the cases in seperate sealed plastic bags with mothballs. Is ther a better alternative to mothballs? No, I cant afford to replace the cases.

Any and all advice appreciated. Thanks

Spray or sprinkle some kind of insecticide in the case and let it air well for a week or so if the insecticide is alcohol or water based to be sure the lining doesn't go mouldy, and then give the inside a thorough going over with the hoover (or Dyson) to get all the dead bodies and other debris out.

Pull the fabric away (but not tearing it) from the edge of the case so you can get a vacuum cleaner nozzle underneath it, and while the case is turned upside down, tap the base with something (like a wooden spoon or screwdriver handle) and shake it around to shift anything that's inside. Go around the lid cushion with the nozzle getting into all the nooks and crannies.

The only thing to do with the clarinets is strip them down completely, bin or burn the old pads and then have the clarinets fully overhauled. If you're not playing these clarinets at all, strip all the corks and pads completely (and destroy them), clean the keys and joints out thoroughly and then store them in an unfinished state (keep the keys wrapped up in paper or sealed in plastic bags, and leave all the screws in the pillars). At least that way there's nothing for any larvae to devour.

The replacement cost of the cases will likely still be significantly less than the cost of the overhauls. If you're already spending that much...

Do mothballs actually work?

I heard somehwere (and from failry good authority as it was on a television programme) they don't do anything to deter moths or moth larvae, but only make that smell.

In my experience this type of damage only occurs when instruments are stored unused for extended periods so in future give them plenty of regular exercise.
I have never actually found a live larvae in any of the instruments or cases where the damage occured although another repairer here in UK did actually find one recently. It was quite big and unmissable and I think has its own featured spot somewhere on utube.

Years back I unpacked a brand new flute where each joint was sealed in plastic bags from the factory to find some pads were eaten away, and the larvae were still in there.

A good way to kill larvae and eggs is in the deep freeze. So if you can put the cases in the freezer for a couple of days that should do it.

Not the horns obviously!

I think mothballs act as a deterrent to moths arriving on the scene rather than getting rid of ones already in residence. I find lavender oil to be a good alternative, although not in relation to instrument cases.

I'd be really cautious about insecticide in the vicinity of something I plan to put in my mouth!

Yes. My husband worked for the EPA's Pesticides Division for 28 years. He seconds this warning about pesticides. I've bought flea market clarinets with moth-damaged cases and pads. Thoroughly washing out the case, then drying it open to the sun in below-freezing weather, while cleaning and re-padding the clarinet before putting it back in the clean case, has worked for me. I prefer physically washing away vermin rather than poisoning my case.

Hello,

I have no moth experience, but did disassemble, clean and subsequently re-assemble a clarinet case. If replacement is not an option/ undesirable, why not just clean them? Since you said any advice was welcome, I suggest this procedure.

I did this to a clarinet case and was well pleased with the results:

I very carefully removed the liner and washed it (it may shrink a bit, but fabric is easy to find- mine was fine and still fit). You may have to soak the liner and the foamy form that the instrument pieces fit in, to separate the two.

I then took a tiny paint/ drywall scraper and scraped all of the old glue off of the now exposed wood (in this case) of the case itself. I replaced the 'divider' that separates the accessories spot from the rest of it and washed the whole thing. Then I used a tiny amount of 'Zud' to get rid of any rust marks on the case hinges, etc. 'Zud' is very poisonous, so I wouldn't use this in the case, even if there is something metal and rusty on the inside.

Then I washed the whole thing in soapy water and let it dry in the sun. The liner I washed by hand with laundry soap and let air dry. For the foam form, I used a very soft, child's toothbrush and water to scrub the residual glue off it of without damaging it.

My case has a top half that was stuffing, rather than shaped foam, so I just replaced it with new, synthetic, non-smelly polyester sewing stuffing; it did take a bit of experimenting to find the right replacement amount :) I then re-glued and assembled the whole thing and let it air dry for days. Afterwards, I closed the case and left orange peels stuck with whole cloves in it and left that. Finally, I removed the orange peels and just left some cloves in the case. I don't know if this would repel insects; I just like the smell. It is something to think about though, as some spices do repel certain insects and they're harmless.

I now have a case that matches the instrument, but I can be sure that it's clean and it no longer smells like mildew, as it did when I bought it. The only harsh cleaner used was the aforementioned 'Zud' and it was only used sparingly on the outside.

I don't like dirty things and regardless of whether or not you succeed in killing the eggs, larvae and moths, it will be still be dirty if it is not actually cleaned. Vacuuming is not really thorough enough, in my opinion, because any grime that seeped into the lining, etc., would remain.

This whole process took me about a day, but it was worth it. No one looking at that case would ever suspect the sad neglect it endured. It only makes me wish that when I bought my first clarinet, I'd have taken the original case, but I was offered a choice and remained unsure about how to clean it back then, and knew that a dirty case would bother me. Based on my case-cleaning success, I now look on that certain site for a case that matches my first clarinet.

To see the live pad eating bug in residence on the F#/C# tonehole search for "clarinet monster" on u-tube.

Just wanted to add that re-lining the case works, too. Take everything apart as Margaret suggests, wash the wooden or plastic inside of the case, dry it out thoroughly, then replace all the fabric and padding with new. I've re-lined several old cases that came to me with old padding and fabric in "Eeewwww!" condition. It's not a terribly difficult job. I've also converted some sturdy attaché cases into clarinet cases for used instruments sold naked.
