G'day Sarah,

You'll need to remove the refill from the foil packet before popping it into the zapper. There is a diagram in the user guide that shows the correct way to fit the refill, the holes in the top should be facing you when you insert it.

G'day Russell,

The X180 Mozzie Zapper Tablets don't list a specific shelf life while sealed. They'll need to be used within 25-30 days of opening the packet, but if they packet remains sealed we can't think of a reason why they wouldn't last for a few summer seasons.

G'day Cath,

The two major chemical components of the tablets are Vanillin and Propionic Acid. They do have a slight odour but nothing that I personally find too strong or off-putting. The tablets are designed to mimic the attraction of the human body so removing them from the unit will probably limit it's ability to do an effective job of killing the mozzies.
