Not all greens from your garden are good for gutloading. In the August 2004 issue of Reptiles the author states that some will actually cause problems. Broccoli, kale, and mustard greens can lead to hyperthyroidism, an over active thyroid gland. Spinach and beet greens interfere with calcium absorption.
Most articles about gutloading crickets explain that they are not a very good choice. Many pet stores just don’t take proper care of feeder insects. Crickets loose their nutrients within two hours of gutloading. They eat their own feces and each other when not properly fed. This being a big factor in spreading coccidia. Most crickets are fed a poultry mash. This has been associated with reproductive problems because many have trace amounts of pesticides. Crickets can be picky eaters, avoiding high calcium foods if others are available.
Roaches are actually cheaper and retain the nutrients and protein that are fed to them. A colony of 1000 Lobster roaches is about $50.00. Each female produces about 25-40 babies every 45 days. They live about 1 ½ - 2 years. So you have all different sizes to choose from. You buy 3000 crickets (you have to buy a specific size) and they are dead after their 5th instar. About 6 weeks is all the average crickets lives. Crickets smell bad no matter what you do. Not a good choice in my opinion.
Red worms, the ones used for composting, make a better feeder. These are about $10-$15 a thousand and will produce 500,000 in a years time. They have twice the protein as a cricket. They don’t make noise or jump. Gutloading is as simple as mixing it in the soil you keep them in. No water dish for them to climb in and drown like a cricket. No special food, just give them your table scraps. Go to produce stands, your local grocery store. They all have over ripe fruits and scraps of veggies they can’t sell. These are free. Are you raising egg laying herps and need extra calcium for them? Save your eggshells rinse them well, and smash them up and give them to your worms or roaches. We have over 200,000 roaches and about 100,000 red worms and we feed all of them a real calcium rich diet. However, we do get our eggshells in large quantities (200 lbs.) at a local egg farm and purchase our grains at a feed store in 50 lb bags. We were buying 6-10,000 crickets a week, now we use about 1000 a week. Our monthly food bill for insects is about $40-$50 a month now.
