If You Live In California,

and you suffer from a fear of spiders, or arachnophobia as it is known,

this might be a good time to stop reading, 

using a spider hunting tip UsefulWidget the householder was shocked to see how many spiders the grass in his backyard held, here is how the spider detecting light works, cats eyes as we all know reflect light that is shone at them, the same applies to spiders eyes but in a narrower band, just shining a torch at the grass will not make their eyes reflect, but hold the torch as close to your nose as you can and see the difference,

some people did not believe the first video, so he made this second one, all I can say is thank goodness there is not a drought and the grass disappears, think of all of those spiders looking for a new home, your house!
