Flea collar in refrigerator compartment?

I've read that you cut them into 3 or 4 pieces and put them in the compartments and they deter wasps.

We use a few moth balls, but the flea collar would probably work fine too. I think I'd cut it into pieces though. A whole collar seems like a bit of overkill.

I've heard it, but I know that the screens will keep the bugs out, not sure about the other stuff. Better safe than sorry I figure.

I figure the screen isn't going to interfere with the air flow enough to bother. After all it's not like there's a big fan in there, it's just air flow from bottom to top by convection.

Flea collar, livestock ear tags, small pill bottle with holes poked in it with moth balls. Good for refer and water heater.
Does it work? Sure cannot hurt anything, and there are lots of bugs that go right through the screens- like spiders.

I read that somewhere and put flea collars in a couple of compartments where bugs could enter; didn't get any wasp nests although I was definitely in an area that had wasps (mud daubers).

Did it help? Well, I didn't get any elephants either, so who knows.

I've since installed screens in the louvers plus in the water heater and furnace vents; my refrigerator has been perfectly happy in east Texas heat over 100F for days.

I've never heard of that! But I am going to subscribe and see who has.
