Question about Permethrin in Canada!

I've been trying to find some permethrin to use for bug control in the backcountry. Seems to be somewhat difficult to find here. However, I did find these options:

Marketed as use for bed bug killer for the first link; however it's only 0.25% rather the usual 0.5% I see in most US products. https://www.canadiantire.ca/en/pdp/doktor-doom-sleep-tight-residual-barrier-premises-protector-bed-bug-killer-515-g-1590801p.html#srp

Also, there is this. It seems to contain permethrin however it is not marketed for clothing use, was wondering if anyone has any insight or experience as to whether is still may be safe and appropriate? https://www.canadiantire.ca/en/pdp/wilson-home-pest-control-1-l-0593739p.html#srp

Any insight is appreciated!
