Treat my garden pests in an environmentally friendly way

Greenfly can be dealt with effectively with just washing-up liquid and water instead of the usual garden pesticides. Speaking of which, ditch the nasty poisonous slug pellets. Slugs are just like you and me. They love nothing more than finishing the day with a lovely drink of beer. Of course slugs also ruin your vegetable patch so the good news is the beer generally sends them off to the permanent land of nod. What a great way to go, eh?
