A N Other customer review:
We've had THE Red Top Fly Catcher in operation for a week or two now.
Yes, it's getting topped up with flies at an alarming rate. Ther're loads in it!
As I type this, in the comfort and potentially fly free living room, I have more flies than I can ever remember skating across my bald bonce and on other, more intimate areas.
Having followed the instructions on the package, to the letter, I can with experience, say that my personal opinion is it's not working. Well, maybe it is working in that it's attracting flies to it, but it's not, IMHO, reducing the flies in my house.
Raid's back on the shopping list.
