Are you tired of making the weekly trip to the local pet store when all the ingredients to a healthy diet are in your own backyard? Well, keep that extra few bucks you spend on crickets and freeze-dried blood worms for your frog, reptile, or whatever exotic pet you own in your pocket and buy yourself lunch.
Find a good source of insects. An open field or the neighborhood ditch or even your backyard. Taller grass usually means more insects. When cutting your grass, you'll notice thousands of insects full of protein and other nutrients.
Find a container to hold insects in temporarily. An old gallon carton would be perfect, but it will get disgusting, so constantly renew it.
Place food in it. Insects won't live long without food. Anything in the vegetable/fruit family will work. If you have a fire-belly toad, feeding carrots to their future meals will help keep the orange color from fading.
Start your hunt. Grab a mesh net or something with the same effect to assist you. When you get an insect in your net, immediately open your container. Grab the insect, and put him in his new home, and quickly cap it. Look for crickets (appropriately sized, of course), moths, grasshoppers, small beetles, etc. Don't try to catch too many flying insects; they will fly right out of the container when you open it.
Open the lid to its cage. Open the cap of your container, and wait for a few insects to fall in. If any die, take them out and trash them. From that point on, it's basically trial and error. See what your pet will and won't eat.
Either toss the container for a new one, or wash it out and start over.
Don't be afraid to touch the insects if necessary. Most of them won't bite or hurt you.
Put a layer of dirt at the bottom of your container to make the mock habitat more realistic to the insects, but be careful about letting it fall into the tank when you're trying to pour insects.
Spray the inside of the container with water lightly, so they have something to drink. Don't over-spray. Crickets are stupid and will drown if you place even a small amount of sitting water in their habitat.
Don't forget that insects need to breath too! Grab a thumbtack and place several small holes in the top of the container, so insects are less likely to chew the holes bigger and escape.
Wear pants and use Off when searching for insects to avoid unwanted visitors.
Dust the insects with calcium dust to improve your pets health.
Don't ever catch spiders, adult mantises, ticks, or wasps, bees or hornets, as these may injure you or your pet.
Don't try to catch something if you don't know what it is.
Make sure you didn't recently use pesticides.
Never feed insects larger than your pet can handle. A small frog cannot ingest the same things a bearded dragon can.
If you are an adult, you may look stupid trying to hunt bugs in an open field. Best to stick to the privacy of your own backyard.
Feed your pet wild crickets at your own risk. They can be dangerous to pets. Everything else you find should be okay (assuming you know what it is).
