Hi Val, I was saddened to see the article on tag advocating a wholesale chemical attack on a roof against guêpes. Yes guêpes can be a right pain however they are incredibly useful in the garden. They collect caterpillars & aphids to feed their young not to mention pollinating many plants & being a source of food for birds. Jam jars with a mixture of jam & water with a hole punched in the top work as a good trap, panache & syrup drinks also work. A balanced eco system in a garden with a few traps out will keep them under control which is surely what's necessary. Our eco system is a fragile thing & annihilation of anything & the use of chemicals does no favours to anyone or anything in the long term. Just my views as a successful organic gardener.
