Lavender candles/scents (Rainier beach,)

Does anyone have any lavender-scented candles (or other lavender scenting things) they're not using? Our house has a major moth problem that we've been treating with lavender scents and moth traps - moth traps and candles seem to do the trick, but the candles need to be replaced more often than the traps seem to and they're hellishly expensive at the rate we're using them.
