Sometime around late September/early October last year, a spider decided to settle into the upper right corner of my balcony. At the time, I decided to just leave it alone as winter was approaching and I figured the spider would naturally freeze to death.

However, when I cleaned my balcony back in April, I discovered to my surprise that amidst the cobwebs was a live spider. So I squashed it, swept away the webs, and called it a day.

Fast forward to 2 weeks ago, and I noticed that that particular corner of the balcony was once again developing white fluff. Again, I killed the spider and swept the cobweb away.

Yesterday, I decided to clean the exterior balcony windows, and... well, I'm sure you can all guess where this is going - a bunch of baby spiders along with a bit of fluff were in that particular corner of the balcony. Again.

How can I get rid of my spider problem once and for all? I live on the 9th floor of a high rise, so it's not exactly like they're just crawling in from the garden every day...
