Re: [ARSCLIST] Pest Control

Hello to all, First post
No need for all these "cides"
Silverfish: They preferred food is Natural Wool fibre Give these unwanted guest's
some, put some of it in your drawers, shelves wherever you are storing collections,
they will go to that before they go to the labels sleeves or covers.
A good material is Felt. Fold the felt over a few times, they will crawl inside the folds and stay
there, if and when they get in anywhere you don't want them to be
You can dispose them (felt included) out in intervals so as to keep the population down
Their life cycle is as an average 30-90 days, weather, moisture and temperature,
dependant, there is a need to monitor initially for their cycle in your location if there is a large number of them scattering around when you disturb them
Old (or new) woollen socks are good as well
When receiving material in boxes from unknown sources cover them with a felt blanket folded over a couple of times and leave them covered for a few days They will come out for a "Feed" You can than dispose of them somewhere safe
(Hunger it's a bad thing)
Your local billiard saloon will tell you of suppliers or off cuts from
replacements of billiard table felt Hobby stores also carry it
Cockroaches: Cedar wood balls, they can be bought at organic stores, or
feel good stores, new age, Incense suppliers etc, cheap and effective
Camphor wood: balls or chips effective for both, simply place them in a
couple of old socks Silverfish and roaches wont go near them, if they do
they will not stay there for long For some reason it is not their favourite
smell or whatever
A combination of all of the above does the trick
This is not quite killing them "in situ" However it keeps them away from things you don't want them to go near
If you do want to kill them Diatomaceous earth spread around the suspected entry points will certainly do away with them it is easily obtainable from fertiliser suppliers specialising in organic inputs to farms, they would most likely have it
None of the above have any adverse effect on records book etc
Try it It works quite well and you do not have to deal with "cides"

Thanks George. We're fairly sure that silverfish entering the collection
have not been attracted by humidity as we have had consistent humidity and
temperature control for many years.

We are setting up a quarantine area and procedure to eliminate pests
entering with new accessions. However,  it appears that some have already
setup house in the archive.

Given the choice between silverfish and archives we think the silverfish
will find plenty of food elsewhere. Due to the lack of evidence of a large
population (less that 6 sightings in 10 years) we won't be rushing to apply
anything until we have done more research and setup more preventative

We will follow up on your comment re: Piperonyl Butoxide and Naptha, and
explore alternative means of application.

Dear Marie (O'Connell),

----- my experience is that silverfish require humidity--your storage area
may be too humid or drawing humidity by capillary action. They digest
and I know from experience that they may eat parts of labels on 78s, giving
them a unique relief, because the printing has protected the paper. Glossy
paper sized with plenty of starch becomes very rough.

Permethrin is an artificial pyrethrum, and it is very effective. It is
usuallly available in powder form and in an acqueous solution. I do not
the look of your gas, because it has the quite unnecessary ingredient
piperonyl butoxide that has probably been added to increase the useful
But it requires a solvent, hence the huge amount of naphta. Permethrin does
break down by oxidation and in light, and the treatment may need being
redone, if the humidity problem has not been solved. However, only real
crabs, shrimp--and insects are harmed by it.

Many years ago I asked our pest control authority about silverfish, and
said that they were among the oldest organisms on Earth, and that it would
really be a pity to eradicate them. So, it is your moral choice: to
silverfish (give them the right humidity) or audio.

Kind regards,
