No idea, but interesting question. I never use fly sprays myself - I use hairspray which gums their wings, makes them drop then you get rid however you like. You can be assured they will have well coiffed hair wherever they end up ! ! I'm looking forward to a real answer to your question.

Shouldn't do, Nosey, but it does depend on the active ingredient - if its a pyrethrum or something, it's fine.

thank you bamboo much apreciated x .

great idea to silverbell at least they die with a decent parting lol x .

Ha! Ha! Very good nosey - wish I'd thought of that line myself. If there's no copyright on it I'll remember the line for future use.

Now i'm going to find out about the spray you're talking about.

lol x .
