Advice?: Concerns over permethrin use in the household.

[Kaiyo_no_Okaami]

So, a household member is going camping at the end of the month and just mixed up and used a batch of permethrin on his tent. Its main use, as I understand it, is against ticks.
Which are arachnids...

Does anyone know just HOW paranoid I should be?
The user claims everything was cleaned with bleach (which apparently will degrade and eventually neutralize permethrin). But this also is a man who frequently leaves wet, floury fingerprints around the kitchen when he bakes, and notoriously puts away my scale with flour/bits of wet dough on it. I can't be super sure how careful he was.
I'm slightly afraid to touch anything relating to my spiders for fear of contamination.

AND he used the sink I usually use to clean water dishes (etc) in. ‍

I'm really trying to remain calm and not panic here. At the same time though... My tarantulas!
I'd be concerned no matter what species I had, but I have Cyriocosmus sp. Tambopata. They're fairly new to the hobby right now and still fairly rare (afaik, at least in the US). Plus, they're still slings. (Ish? Most recent molt measured around 3/4" or about 19mm DLS.) Especially as someone relatively new to keeping Ts, I would be devastated if something happened to them.

Should I be going over every last inch of everything it might have come in contact with using bleach? Permethrin apparently breaks down in about 4 days in the sun, but can last around 4 weeks otherwise.

I also have no idea how easily teansfered this stuff is when dry. Or if water will reactivate it. Etc. The internet has not been very helpful with this so far.

Thanks in advance.

I pulled up the MSDS sheet on Permethrin at work. Just another warning if you have any cats, it is highly toxic to felines. It has a 10 year shelf life. Only thing listed to neutralize it is >94% strength bleach. States that even heavy rains will not wash away the Permethrin. Oddly enough Permethrin is only active when it is dry. So adding any sort of liquid other than bleach will do nothing to clean up Permethrin.

Hope any of this helps. Good luck

Thank you!
I spoke to him again and got some clarification. He did clean everything with bleach and I wiped down surfaces with bleach myself as well. Just in case. So far there have been no issues thankfully.

Thanks for the reply. I agree it was probably overkill.
Though he applied it outside away from the house. Just cleaned the sprayer inside. At the time I was using that sink to clean enclosures and tools so I was concerned.
