Have you ever truly smelled moths balls? I haven’t, I haven’t even seen any! They must be quite tiny considering the size of moths. If anyone can smell moth balls I congratulate you on your hypersensitive olfactory receptors!!

This puts me in mind of an old joke;- "What to do you get if you hold one moth ball in the left hand and one moth ball in the right hand?" Answer,
"Complete control of a very large moth!"

I use cedar oil on the lips of the drawers and 1sq cm pieces of Vapona on yellow headed pins. Why yellow pin heads u wonder....? I used to use SS insect pins, but they were harder to see and I split a few wings by accident. Vapona pieces last a long time depending on how often you open drawers. To me, it’s the least of all evils...pesticide wise to humans. Some will differ, but that’s worked for me for years. And yes.....for several reasons including what Leroy mentioned, the drier the better for the whole insect room/area. I also use heat treatment as opposed to freezing when putting stuff into the drawers. No dermestids for last 20+ years.....knock on wood. In 50+ years, have only had one or two minor incidents........probably carelessness on my part. Hello, I never had problems with dermestids in my drawers. I always freeze specimens before putting them in a drawer. I guess that good drawers are tight enough to avoid dermestid larvae getting inside or even females getting inside and laying eggs. But I use to get booklouse (Trogium sp.) in my drawers, stored unmounted insects and setting boards. To avoid these tiny insects getting inside my drawers I use strips of moth paper whichs contains 5 g/kg empenthrin (Pyrethroid). As far as I know, this insecticide is being banned in many countries due of its toxicity. Some moth paper manufacturers are switching to geraniol, transfluthrin, prallethrin... As I read this post I bought cedar oil and used it in a small arctiidae box, which was in the freezer before putting the oil. On 1st August 2020, 5 mL of cedar oil were placed in a glass container inside the box and it was stored at 25 ºC. Today, to my surprise, I discovered several alive booklouse (Trogium sp.) in the box: So I must state that cedar oil ist not effective against booklouse. Do you have any experience with this kind of pest in drawers? They are tiny enough to get inside almost every box/container... Thanks crino

Cedar oil never kills pests just deter them from entering the drawer, if that even works, I’ve never tried it. Try to get Vapona strips, they are highly effective.

Thank you Paul, I'll try it. Before using moth paper, I placed 20x20 mm pieces of a brownish plate in my drawers and they were effective. They were about 3mm thick and they could be easily cut using a cutter knife. I remember they were from BAYGON. But after the 90s these plates were not available anymore and I was forced to switch to other products. Who knows what they contained!
Regards

The best thing to do is freeze whatever you can for 3 days, remove it for 8 days (eggs, which do not die when frozen, hatch in 1 week) and freeze again for another 3 days to kill all the remaining Psocids that hatched. Spray the whole room with insecticide a few times over several weeks, as there will be Psocids in books etc as well as your specimens.
Remember that naturally they eat fungus, so try to reduce the humidity in your collection room as low as possible. If you can get a dehumidifier or aircon unit and reduce humidity to 20% it will be ideal. They don't survive in low humidity.
Adam.

Are we testing the waters of debauchery and tastelessness again leptraps?
Remarks like the one above only lead to worse ones; we all know you have a long history here of making those.
How about REALLY trying to keep your remarks clean, respective, and scientific in the foreseeable future...

How about REALLY trying to keep your remarks clean, respective, and scientific in the foreseeable future... Now I'm worried. To stay on topic, I hope moth orbs don't get banned here in the states, I know Bioquip sells that dichrolovos or whatever it is, it sounds a lot like those Raid No Pest strips everyone used to have hanging in their houses, quite a bit more expensive than circular moth crystals. Personally, I think moth control for closets isn't going to have an adverse effect on a person's health, unless you do something weird with it...Typically, the only issues I have are in Riker mounts, and those are just extra specimens taking up wall space and looking pretty, and those are far from being pest proof.

Yes, rikers, as is, are not pest proof one bit. The trick is to place a piece of Vapona underneath the poly fill at the bottom and then tape the riker shut w electrician’s tape. If done correctly, rikers can go many years wo a single dermestid. My mother, after she passed, had a riker I gave her from the early 70s that still had no pests although the specimen was faded. She passed in 2012. With the few rikers I use now, I mark the spot where the vapona is and years later, cut open that corner from the back, put a new piece in, and tape it shut. The fumes stay in the riker and kill any invaders. One must be careful taping it so as to leave no seams......and....don’t stretch the tape at all. After the tape is on, I rub the tape on the frame with the handle part of scissors to help the tape grab the textured cardboard. Warm, but not hot tape helps too. Vapona is, imho, the best pest control.......I’ve not had anything invade my drawers for many many years. My cedar oil use is only to act as a deterrent/repellent. It does not kill. Vapona does.

I find the best thing to use as a DETERRENT is one of the essential oils like Citronella. I have been using it now for several years with no problems at all. A couple of drops in a corner of a drawer or in the chemical slot works great and smells nice as well. Of course Citronella is a natural insect repellent so is TOTALLY safe as well.

The real question here is : Why are moth balls so small ??
Answer: Because not all that many moths can dance.

I'm sure everyone else has had the same experiences, in that pest intrusion is selective and only some mounts have problems, in my house, there are probably a dozen or more mounts with single and multiple specimens, and some riker mounts never have an issue, even when the ones nearby do. Moth spheres don't smell good to everyone, I gift a lot of extra specimens, and usually put in the moth crystal packets until they're ready to go and then remove the packets. For the mounts in the living area, I just keep an eye out for the telltale signs and pop the case in the freezer for a couple days.

I have never understood the use of rikker display cases to store and maintain a collection of insects, especially Lepidoptera. It is difficult to view the underside against the cotton and when attempted, it usually results in the loss of legs and attenae which can be easily broken off when specimens are removed to view the underside.
I maintain a rather large collection. I have 400+ Cornell drawers with an estimated 40,000 specimens and I am being rather conservative in that estimation. However, I can easily remove any specimen from any of my drawers with ease.
As a young husband and father, I struggled to find money to purchase drawers. I learned to make my own. However, I had a great teacher. My father. I now own a larger high quality table saw and Planer. Four routers with three router tables and all the necessary tooling. As part of Leptraps, I offer Entomology Drawers, both standard drawers and custom.
I did not accomplish all of this over night. It took me many years. I must admit, I am not a very good wood worker. However, I make my own spreading boards, Schmidt Boxes, Pin Holders and many other wood items to use in or with my collection.
I even made numerous lamps for our home. I loved to turn wood on a wood lathe.
You are never to old to learn.
