Usually this is how I handle spiders, though I always have some junk mail ready for the task and an empty jar ready. Today there's a moth that was keeping me company on the wall while I drew this. Since it's immobile, I think I'll let it stay for a while. Basically, my reaction speed to bugs is directly proportional to how fast they can come into contact with my skin. If you're far away from me and not coming closer, you're cute! If you're on my desk near my hands or face and moving quickly, the jar will be the least of your concerns.
