Spiders are a gardener's friend.
Well, what I do is get some Ladybugs from the local nursery.
Those girls eat about 50 bugs a night a piece.The trick is to put them out at night.
But before you put them out make sure to water your lawn and any foliage you want them to habitate. You'll also want to water early in the next morning.
This is because the Ladybugs will need water.
And the more water readily available to them the more likely they'll stay longer.
The next time you leave that spider to do his gardening!
