If you don't think a citronella candle gives off enough protection, then perhaps you should consider a
wine-light. You can convert lots of different containers. The problem with full size wine bottles is they tip over easily, and if you have a short wick, you need lots of extra fuel just to reach that wick. So one could put some gravel in the bottle to reduce volume and add some stability.
Also note that the citronella will only work from the level of the device, upward, so this is why citronella buckets are made to be burned sitting on the ground or on a low table, on the edges of the area where people occupy. Any hanging lamp will protect from say head height upward.
Another solution with an authentic container might be a
redware ink jar. Ceramic containers though do not allow you to visually see the fuel level. The same is true for betty lamps.
You could opt for a
Jamestown glass vial for the same price as the ceramic, but you can see the fuel, and you need less fuel and short wics are not as much of a problem as with a full sized bottle. The only drawback is that since they are hand blown, a wine-light
flame protector might not fit.
The most stable bottle that is also historic would be the
hand blown onion bottle, but these again hold a lot of liquid so you might want to take up some of that volume with gravel or glass beads, and also the flame protector might not fit. You will most likely want a flame protector for each wine light.
Alas while I have a Jamestown vial and a wine light converter, I cannot use it at most of the events where I attend as "flammable liquid" is prohibited.
