G'day Andrew,

I don't believe this will work for tarp or groundsheets, as they're generally plastic woven or plastic mesh.
This can only really be used with fabric or material that is porous/permeable.
If you have non-waterproof cotton canvas groundsheets/tarps, you may need a few bottles. Apparently, 20ml of concentrate will treat 2 single bed sheets, if that gives you an idea of rate.

G'day Dianne,

I've checked in with the team & no-one here has personal experience with this product.  Apparently, Permethrin can smell alittle during the application process, but ultimately the smell goes away. A quick google also suggests that Permethrin is odourless, so I think if you're worried about smell, you wont have any issues with this product.

G'day Karla,

There's no clear info on this from the product specifications, but I've done some research on google and it seems people regularly treat merino clothing and socks with Permethrin with no issues at all.
I'd recommend having a google and reading more about people's experiences before you proceed, just to make sure you are happy with that info!

G'day Eric,

I've done some quick research on this one, and it seems as though Permethrin is effective in deterring midges to a certain extent.
Seems like it could be a good option, but isn't foolproof.

G'day Brian,

Yep, that application for swags would be the same instructions as provided for tents.

G'day Sarah,

The ratio of active ingredients (permethrin) to solvent is 25:75, so it is 25% concentrated and should suit your needs.

G'day Dave,

Great question! I've had a chat with the supplier and they've said the Permethrin Treatment will last about 12 months and for 30 washes.

G'day Syed,

We wouldn't recommend using the Debugger on garments with DWR or Gore-Tex as it may damage the fabric or the waterproof membrane.

G'day Mochelle,

The instructions supplied with the Debugger Permethrin Treatment indicate that items must be submerged in the solution and left to dry. You may be about to make up a solution and put it in a spray bottle, but it would be hard to determine the effectiveness.

G'day Jodie,

I've just been and checked the instruction manual in the box, and they suggest that you can use 10mL of the Permethrin Treatment with 4L of water to treat up to 4 shirts at a time.
