Four strikes a season in eight months? That seems pretty low to begin with. People buy the full screens because the dots only work if the bugs actually land on them, and most of the time they just fly around them. Six dollars of tape versus a real screen is not the same thing, one blocks the opening and the other just hopes the bug hits a sticker. Maybe your building just has a light bug problem and the dots got credit for that.

Cancel that contract, waste of money.

Curious how you actually spot real soy wax at a yard sale since most sellers have no clue what's in the jar. Do you check for that smooth, cloudy look and a wick that isn't poking out all stiff? I keep getting burned on mystery wax, so a quick test would help.
