I work at a university, one of my coworkers was reaching into one of the soda machines and felt something crawling up his arm while pulling out a soda.. he shook it off, turned out to be a black widow.. female, about the size of a dime.. we looked inside the machine and saw it had laid a ton of spider egg sacs by the hole and on the back.. looks like this:
If you see that shit then they have set up shop... destroy their webs/den/sacs, I would bomb those fuckers since they have about a 5% fatality rate and getting bit by one is pretty painful ive heard. bomb the inside of the car and then air it out. Check the car throughly. Infact, I would park the car in the garage, close the door, bomb the garage/outside of the car and throw a bomb underneath the car just to make sure I get everything.
