When I kept tarantulas I fed roaches and only roaches. I hate crickets because of their smell, the chirping doesn't bother me personally.

@reptiliachnids - Scientific names are useful with all animals and especially arachnids which tend to have more common names than most. When you write out scientific names however, only the first letter of the genus is capitalized. The rest, including species/subspecies, is lowercase(e.g., Brachypelma smithi). Just thought you'd like to know this tidbit.
