Are they types of chemicals controlled or banned in Switzerland? Can they be bought if someone knows where to look? Drogerie, special pet stores, professional supply??
If I order from outside CH is it a problem?
Thanks.
There are some products Im looking for but unable to find. (Permethrin, Bayer Delta Dust, vet supplies, and similar.) Id guess these would be considered stronger products for insect, pest, weed control. They are commonly used in other countries for agriculture, livestock, residential gardens. Ive checked Landi and other garden centers and mainly see simple stuff for house plants and very basic gardens.
Why not give the stuff Landi sells you a try? At least you know it is not a banned product.
Landi, drogerie and the like have some products in locked cabinets behind the counter and you have to ask for them.
Depending on what it is you might also have to fill out and sign a form.
I've bought from Sintagro before, they sell a range of products online and typically more than you'll find at Migros or Landi.
You need to look online at the labels of the products you used to buy and see what the active ingredients are and then check three things:
Firstly whether they are banned in Switzerland
Secondly, are they banned for the use for which you intend.
Thirdly, what products are available here which contain the same ingredients.
For example, Deltadust contains Deltamethrin as the active ingredient and quartz dust as a carrier.
Here you can find an official list of all products that contain it:

If you scroll down the list you can see it available as an insecticide for topical garden use here
You may not be able to get it in a powdered form for gardens here as in Deltadust due to it's ability to be spread uncontrollably by the wind and it's devastating affect on the bee population but it may be available in powdered form to treat animal flea infestations.
The only safe way to do all this is to only buy locally and see if you can find an equivalent as outlined above.
Here's a good link for treatments for animals and toxicology.
Here's the specific link for Deltamethrin
Is your interest into chemicals for agricultural use related to this:
Whatever is present in your garden, eradication is not a solution: you will end up erasing the flora&fauna variety, letting only the dangerous plants/pests surviving.
This, and leaving a chemical deposit in or on the earth, and whatever grows there, which is unlikely to be health-promoting for the garden later nor, OP, for your son.
There are teensy little red spiders, which are not dangerous, but which can bite and leave small red marks, and often the person does not notice until later, when they have, itchy marks. I don't know how to deter them.
There are also ants, big and small, with bites that can leave such marks but usually burn as they are biting. I wouldn't add special chemical poison to the mix. But you can check (shod in solid shoes) and, if you see that it's ants, you can create an ant-barrier with water and/or cinnamon and/or vinegar. Not super healthy for the ants, either, but if you deposit this in a thick line, you divert the ants because they soon change their minds and decide to avoid that area. This may need several applications.

Once had to sign off on Bordeaux mix for the potatoes and tomatoes (blight).
