Live or freeze-dried insects: what should you feed your reptile?
Live insects remain the gold standard for feeding an insectivorous reptile: maximum appeal, natural hydration and the option of gut-loading. Freeze-dried insects, two to three times cheaper per kilo, should only serve as an occasional backup: many animals refuse them and their nutritional value is diminished.
Why is live prey nutritionally superior?
A live cricket is 65 to 70 % water and can be “loaded” with vegetables and supplements 24 to 48 hours before feeding, which directly enriches the reptile's meal. Freeze-drying destroys part of the vitamins and removes all the water: an animal fed exclusively on dried prey risks chronic dehydration, especially species that rarely drink. Our full guidelines are in the reptile food section.
Does movement really matter for appetite?
Enormously. Leopard geckos, bearded dragons and chameleons trigger their strike on prey movement. A motionless insect is often ignored: you then have to wiggle it with feeding tongs, meal after meal. Some individuals get used to it, others never do. Live prey also stimulates hunting, a valuable form of enrichment in captivity.
How do freeze-dried feeders score on price and convenience?
- Price: 15 to 25 € for a 70 g tub of dried crickets, versus 4 to 6 € for a box of 40 live ones;
- Shelf life: 12 to 18 months when kept dry, versus one to two weeks for live prey;
- Zero upkeep: no escapes, no chirping crickets, no box to clean;
- Backup: handy during holidays or a supplier shortage;
- Major limitation: low appeal and no hydration.
What is the sensible everyday strategy?
Base the diet on live prey (crickets, roaches, worms) bought in-store or online — see our tips for paying less for insects — and keep a tub of freeze-dried feeders in reserve. If you do use dried insects, rehydrate them for a few minutes in warm water and dust them with calcium just like live prey.
Frequently asked questions
Are canned insects better than freeze-dried?
Slightly: canning preserves moisture, and therefore hydration. Appeal still lags behind live prey, and an opened can barely keeps two days in the fridge.
Can a reptile live on freeze-dried insects alone?
Strongly discouraged: deficiencies and dehydration set in silently. Keep dried prey to less than one meal in four, rehydrated and supplemented.
Is gut-loading really essential?
Yes: an insect fed bran and fresh vegetables 24 hours before the meal passes those nutrients on to the reptile. It is the main advantage of live prey, impossible to replicate with dried feeders.
