not fond of wasps, having been badly stung on the neck once. But thanks for the tip that they're just after the BBQed chicken. Hope they like spicy marinade

Slugs though.....I've given up now on all the eco friendly, gentle solutions. Napalm on the order list. I also succumbed to ant powder (although got most of it on myself) and an ant bomb. They stripped my juicy fat strawberries in under an hour. And have eaten my gerberas ( a capital offence).
The 4 year old in the basement flat told me today that if she wakes up in the middle of the night, she'll go outside and jump on them

PS I love bumblebees. We have giant ones that fly into the bedroom, but lots of normal ones feeding on the sage and lavender. Just planted more lavender too. The local schools in my area of London are now keeping bees.
