Tricky one - in areas where rats are already resistant its already too late...
On the whole I agree with you, encouraging people to dispose of food waste/compostable waste more responsibly would do a lot, but then a lot of people are battling with local councils refuse collection rotas that mean food waste is sat outside for a fortnight at a time.
More and more people are being encouraged to compost as well, which done well is fine but done untidily can easily provide rats a des res and 'all you can eat' buffet..
Sensible use of the poisons we already have would go a LONG way - they are not nice, and they are not always appropriate and I do think in situations where terriers ARE safe, they ought be used (though Im not seeing local councils providing terriers to their pest control officers..).
In most built up areas, in factories, hospitals, restaurants..... terriers are not a practical option (in a lot of council carparks with their delightful raised shrubberies placed right next to overflowing wastebins, a terrier or two and some judicious hole blocking/smoking them out would be ace, ditto many school grounds!).
In those instances not only does poison HAVE to be used, but it has to be used properly and that means a routine management of pests, rather than only putting poison down when populations explode, putting poison in the right places (ie where rats actually go and will eat), making sure that there are not alternative food sources...
All too often companies (never mind individuals) try to save money by doing it 'diy' and popping trays of poison down in places rats wont eat it in sufficient quantities, (big cause of rats becoming resistant), or NOT tidying up/removing alternative food sources (again so rats dont eat enough poison... increase in resistant rats).
I dont think stronger poisons ought to be made widely available but from the article it looks like that ISNT whats being requested anyway.
