I agree with Pheathers completely...if you don't use pesticides or fertilizers on your lawn collecting your own food can be a very economical and rewarding way of supplementing your frog’s diet. I've used wild-caught foods for my amphibians for years; not exclusively, but probably close to 50% of the time. I collect these food items from various sources that are just as safe if not safer than commercially bought foods. I've worked for the state of KY as an environmental scientist for years doing reclamation on abandoned coal mines which entails macroinvertebrate sampling, water sampling, etc. and know many local sources where I have no worries when it comes to wild-caught food. When you're buying live foods no commercial vendor is claiming their products are parasite and pesticide free...

Claiming that all wild-caught foods are bad for your animals is a knee-jerk reaction that is overused to a large degree. What needs to be considered is the sources for these food items. If you're a home owner you know what you're putting on your lawn and what you're not. Folks with various degrees in natural sciences and related occupations might also have a good working knowledge of where safe sources can be obtained from the wild. These things should be considered before dismissing all wild-caught food items and repeating one of the most overused responses there is when it comes to wild-caught food items.
