Toads are generalist insectivores, and yes, they do eat crickets. Crickets are a common and available food source, particularly for those kept in captivity. As opportunistic predators, toads consume almost any invertebrate they can successfully capture and swallow. Crickets are often considered a dietary staple because their size and movement stimulate the toad’s feeding response.
The Toad’s Hunting Mechanics
A toad’s hunting strategy relies on ambushing prey, using visual cues rather than scent to initiate a strike. They are “gape-limited” predators, meaning they only attempt to eat prey items that fit completely inside their mouth. The movement of a cricket generally triggers the toad to launch its attack. The capture is an incredibly fast process using a specialized, sticky tongue. This muscular structure is rapidly flicked out and retracted, adhering the prey to its surface, making it an effective mechanism for capturing small, fast-moving insects.
Crickets as a Primary Food Source
Commercially available crickets are frequently used as the main diet for captive toads because of their convenient size and high protein content. However, crickets are naturally deficient in certain nutrients, particularly calcium and Vitamin A. Their exoskeletons contain chitin, a fibrous material that is digestible but adds little nutritional value.
To correct the poor nutritional profile, specifically the low calcium-to-phosphorus ratio, crickets must be prepared before feeding. This is accomplished through two methods: gut-loading and dusting. Gut-loading involves feeding the crickets a highly nutritious diet for 12 to 48 hours before they are offered as prey. This ensures the toad ingests the beneficial contents of the cricket’s digestive tract.
The second method is dusting the crickets with a calcium and vitamin supplement powder immediately before feeding. This is crucial for preventing metabolic bone disease (MBD), a serious condition caused by calcium deficiency. Dusting achieves the necessary calcium concentration on the cricket’s surface, helping to bring the calcium-to-phosphorus ratio closer to an optimal 1:1 or 2:1.
Expanding the Toad’s Diet
While crickets are a convenient primary food source, an exclusive diet can lead to nutritional deficiencies. Providing a varied diet is important to replicate the diversity of prey a toad would naturally consume and ensure complete nutrient intake.
Other appropriate prey should be rotated into the feeding schedule. Earthworms (nightcrawlers) are an excellent and favored option. Other insect larvae, such as mealworms or black soldier fly larvae, offer different nutrient compositions.
Waxworms and superworms should be given sparingly as occasional treats due to their high fat content. For larger toads, dubia roaches, slugs, and snails provide additional variety and bulk. Rotating these food sources ensures the toad receives a broader spectrum of vitamins and minerals.
