Woodworm treatment (Colleycroft CV12)

Before I go out and get some does anyone have a bit of leftover woodworm treatment please? I don't need a huge amount. There is some on a wooden handle system on my shed door and we aren't confident it has ever been treated. Also another area of wood maybe 50cm by 30cm.
Can be reasonably flexible on area and pick up. Thanks in advance. Caroline
