I'd probably just use my phone to call 9-1-1.

That is fine for the occasional bite, but what if I plan on being bitten regularly?

Use Amazon Prime to ship you anti-venom in 2 days.

This is one of those instances where you might want to splurge the extra $3.99 to make it overnight.

Or else just use their "Subscribe and Save" system on this item.

"Siri, can you remind me to order some more anti-venom tomorrow?"

We'll it's usually advised that if bitten by a spider you should kill/capture it or take a picture so it can be identified and the correct anti-venom administered.

So yes, do call 911, but taking a picture could be potentially life saving.
