Ah, Happy New Year to one and all.
France and the EU have separate rules regarding animals/insects and plant control, so it’s a minefield out there:
Example 1. Bacillus thuringiensis perfect for killing chenilles processionnaire and box caterpillars, from 1 May 2018 need a different diploma to use commercially, a bummer as I have 40 litres of the stuff sitting in my store room.
Example 2. Racumin Powder rodenticide excellent for confined spaces (voids) legal in UK banned in France for several years.
Herbicides usually require a special licence to use and are banned in most Espaces Verts, including gardens. There are effective alternatives though.
Farmers have to legally obey to ZNT (Zones non traité) usually 5m from a neighbouring property, ha ha ha good luck on that one!
Rodenticides sold to General Public must have no more than 30ppm active ingredient. This is also farcical as I can use stronger bait, therefore use less to treat an infestation. AKA a 2 tier system for rodent treatment.
What they are trying to do makes sense; to stop you naughty amateurs who never read the instructions on the packet. Yes, you, don’t deny it! They are also trying to eradicate the rule of farmers “Grandpère did it so why should I do any different?”.
Pest Control in France is an artisan trade and we spend a lot of money each year on training courses and keeping up to date with new practices. There are a lot of nasty chemicals out there and they don’t want you to play with them without any experience or knowledge.
There are many ways to treat pests without using herbicides or chemicals I have just won a contract for a medium size town for dératisation in their sewage system. My process is non toxic monitoring thus minimum environmental impact.
I can understand why Dr Amateur is miffed, but the nannies are doing it in your best interest!
