At the museum we are currently dismissing Paradichlorobenzene and Naphtalene.
we are looking for other effective chemical or similar.
Dear Filippo Maria Buzzetti
In our museum of zoology, we use sealed wooden entomological boxes. From time to time we lay out the put the plates impregnated reppilentami (we sell them against mosquitoes, mosquitoes, gnats). We have beetles more often, it helps from them. We put stuffed animals in plastic bags with insecticides for a day. Although I must say, we used naphthalene for a very long time - it helped a lot.
In general, to summarize, if the entomological box is hermetically closed, then the pests will not penetrate into it.

I'm not sure whether it would give you a straight answer, but Walker et al. (1999) seems to be a good read about general care and conservation of collections:
Walker, A. K., Fitton, M. G., Vane-Wright, R. I. & Carter, D. J. (1999). Insects and other invertebrates. In: Carter, D. & Walker, A. (eds). (1999). Chapter 2: Care and Conservation of Natural History Collections. Oxford: Butterwoth Heinemann, pp. 37 - 60.

Helder Hugo thanks! I know that, I am looking for some more recent info.

Dear Pushkin Sergey Viktorovich
thanks a lot for your suggestion.
We survey yearly the bozes and freeze those infested (only 2 since 2016), but this is the situation with naphtalene used until now.
I don't know if infestation will raise after getting rid of chemicals.....
best regards
Filippo
Use repellents containing ingredients such as diethyl phthalate, diethyl carbate; N, N-Diethyl-3-Methylbenzamide (DEET), metofluthrin, oil of lemon-eucalyptus, picaridin and ethyl hexanediol. https://www.mosquito.org/page/repellents
Common natural insect repellents
Oil Jar in cow horn for mosquito-repelling pitch oil, a by-product of the distillation of wood tar. Carried in a leather strap on a belt. Råneå, Norrbotten, since 1921 in Nordiska museet, Stockholm.
Beautyberry (Callicarpa) leaves
Birch tree bark is traditionally made into tar. Combined with another oil (e.g., fish oil) at 1/2 dilution, it is then applied to the skin for repelling mosquitos
Bog Myrtle (Myrica Gale)
Catnip oil whose active compound is Nepetalactone
Citronella oil (citronella candles are not effective)
Essential oil of the lemon eucalyptus (Corymbia citriodora) and its active compound p-menthane-3,8-diol (PMD)
Neem oil
Lemongrass
Tea tree oil from the leaves of Melaleuca alternifolia
Tobacco
https://en.m.wikipedia.org/wiki/Insect_repellent
Common synthetic insect repellents
Methyl anthranilate and other anthranilate-based insect repellents
Benzaldehyde, for bees
DEET (N,N-diethyl-m-toluamide)
Dimethyl carbate
Dimethyl phthalate, not as common as it once was but still occasionally an active ingredient in commercial insect repellents
Ethylhexanediol, also known as Rutgers 612 or "6-12 repellent," discontinued in the US in 1991 due to evidence of causing developmental defects in animals
Icaridin, also known as picaridin, Bayrepel, and KBR 3023
Butopyronoxyl (trade name Indalone). Widely used in a "6-2-2" mixture (60% Dimethyl phthalate, 20% Indalone, 20% Ethylhexanediol) during the 1940s and 1950s before the commercial introduction of DEET
Ethyl butylacetylaminopropionate (IR3535 or 3-[N-Butyl-N-acetyl]-aminopropionic acid, ethyl ester)
Metofluthrin
Permethrin is different in that it is actually a contact insecticide
A more recent repellent being currently researched is SS220, which has been shown to provide significantly better protection than DEET
Tricyclodecenyl allyl ether, a compound often found in synthetic perfumes
