A short time later I saw that the b/flies had got out and
flown off but the ones that I hit with the spray where
laying on the ground dead.

Fairy liquid is fast becoming my best friend.

What dilution did you use Wally?

Judith

Not all that strong Judith, I didn't measure it but my spray bottle
is two litre and I added about an egg cup full of soap.
