QUESTION ABOUT SILVER FISH (LEPISMATIDAE)
HELP! I HAVE A LOT OF LEPISMATIS (SILVER FISH) IN THE HOUSE
QUESTION OF SARA
Unfortunately, I too have the same problem as the lepismatidae.
I have a lot of them, I find them in any room of my house (entrance, living room with kitchenette, double bedroom and single bedroom), a little less frequently in the bathroom.
I am very worried because in addition to seeing them running around the house, they are found everywhere:
- in the cupboard with dishes and the pots inside them; - in the shoe cupboard inside them; - in the closet; - in the drawers and closets for linen and clothing; - and finally in the bed and on the sofas tucked into the slipcovers.
I panicked and I am terribly afraid ...
Surely as soon as possible I will try the method, recommended by you, of the jet of steam with boric acid.
I have a few books but I've never seen them in those places. There is no carpet or parquet in the house.
He sees them when I return to the walls late in the evening and they slip into the skirting board, more or less the daily quantity I see of lepismatidae varies from three to six, of any size (in this period I noticed that there are many small ones ).
Since I'm terrified of finding them again in the drawers, in the closets, on the bed and on the sofas, is there a way to keep them away from these objects?
Is it true that by depositing camphor sachets inside the aforementioned (wardrobes, drawers, sofas and bed) the lepismatidae move away and do not enter? Otherwise what other method can I use?
Waiting for your reply, I thank you and greet you distinctly.
Dearest Sara, it is a big problem that will require perseverance, persistence and patience on your part to be able to eliminate them.
Now, I would not want to alarm you further but it is good that you know your "enemy" very well to be able to fight him better.
Silverfish are very ancient and exist on earth for thousands of years. They live not only at the expense of paper and books but also of fabrics, carpets, glue, hair, starch substances and even the corpses of their companions (in fact you do not find anyLepismadidae dead around), in short, a bit of everything They are very long-lived and live several years. They love warm, humid and dark places. Think that, even if they can't find food, they can go on for several months without eating. The silverfish are oviparous insects, that is to say they are born from eggs that are laid by the females and on average with temperatures around 20-25 ° C a female can lay even a hundred eggs in very protected places such as cracks, baseboards, drawers in short, in very sheltered places. On average, the eggs take 30-40 days to hatch and in domestic environments they become adults within a year. They grow by moulting (obviously you eat those too), generally it takes ten moults to reach the adult stage but they continue throughout their life, up to even 70 moults.
Now, completely eliminating them will require a lot of persistence and patience on your part. In any case, you will see that in a short time you will be able, at least to reduce the number.
I recommend that you do the boric acid treatment right away. As you will have read in the answers I gave to the other people who wrote to me about this problem, I always recommend this treatment and in your case, to do it repeatedly once every 20-30 days for at least three times in this way you can eliminate new generations of eggs.
I've never read that camphor has any effect on these insects so I can't tell you.
There are no large studies or researches on silverfish, also because at a domestic level, there are rarely large infestations that concern more the large pasta industries, wood production, etc. and they use other methods for pest control that obviously are not applicable to a domestic environment.
I will therefore suggest you some complementary solutions to the vaporizations with boric acid, not really scientific, some empirical but that could help.
Between vapes, you can use baits or traps. They are not very effective but they help to fight them, considering the fair amount you have in your home and the discomfort they cause you.
The traps / baits you can use can be different: a mixture made up of half sugar and half borax (boric acid is fine too) that you will place in the places where you see them most. However, you cannot put this mixture in the drawers where you keep the linen or in the cupboards or among the dishes. Both laborace and boric acid, although non-toxic, are still irritating and by ingestion, inhalation and contact with the eyes and skin they have an irritating action.
I have read of two products that make them move away but do not kill them: one is ammonia and the other is their dried leaves. Now, I do not guarantee the result because I repeat, it is not scientifically proven, but being easy to find and low cost products, you could try. You can arrange laurel in drawers and dishes while for ammonia, a product that you certainly know well, you can see how to use it, remembering however that it is irritating.
Another method, which I have read, also empirical but of which I do not guarantee you, is to spray a damp white rag (it seems we are attracted to this color) of normal plaster and always place it near the place where you see them more and leave it overnight. Personally I have not experienced it, but even in this case, trying does not harm.
Here, these are my recommendations, but always keep the vapor treatment with boric acid as a point of reference.
Have patience, do not be discouraged and above all do not be alarmed. You will see that over time you will be able to eradicate them.
