Other insects can be caught, most notably vinegar gnats, isopods, some types of moths, and if the rim is level with the ground it is a pitfall for some spiders and beetles. Being level with the ground is best though. Cover them with something to keep the rain out. Change the beer once every 2-3 days at least.
If you don't have beer or don't want to buy some, you can use water, a bit of sugar, and baker's yeast. Just mix it all together.
