Garlic is a good idea but might be a little tricky as she eats dry food. I wonder if dosing her with humus or garlic and onion dip will work? I've got tea tree oil as well as I've been dabbing it on the worst of my bites (I come up a treat when I get bitten ) so I'll give the fleabag a rub down with it as well. As well as spraying we've been treating the flooring with a powder that you sprinkle and then vacuum. I also like the lamp idea. I'm already drowning any I catch in a jar of soapy water but this will be an additional murder spree to enjoy.
