Glueboards are wonderful things

When we lived in Southern California, we caught scorpions, small snakes and of course a wide assortment of insects and spiders on glueboards, also known as "sticky traps". They don't involve pesticides, so you can put them anywhere. In addition to catching creepy-crawlies, you are monitoring the pest population, so you'll know what's around before it's become a major problem. Then just throw 'em in the trash. This glueboard in the laundry room caught a large spider, with just the body about an inch long:

We also realized that one or more cats were getting into the laundry room at night through the metal security door that has bars at the top. I just installed a screen to keep them out. No kitties were harmed.
