Any ideas of an economical way of either stopping this of covering the

I am not concerned about the EEC directive, just the mess.

If you don't mind what it looks like diatomeous earth will absorb most
things to render them fairly inert (upto and including nerve agents). Do
not breathe the dust. It is one of the natural Organic(TM) remedies
capable of doing serious damage to your lungs. And effective on slugs
and snails too.

It doesn't do too bad a job with nitroglycerine either. Ask Nobel...
