Locusts are typically more expensive than crickets. A tub of 6–100 locusts can cost approximately 2–9 bucks (2–8 pounds), whereas a tub of 25–1,000 crickets only costs about 3–8 bucks (3–7 pounds). However, it’s important to consider that locusts are more or less twice as large as crickets. So fewer locust nymphs can fill up geckos faster.
