With 2,100 worms per bag, this is the highest-volume option on the list and the most cost-effective choice for keepers with multiple spiders or those wanting to start a breeding colony. The mealworms are consistently described as “extra large” — some reviewers noted they rival superworms in size. Each worm is gut-loaded on a nutritious diet before shipping, meaning your spider gets calcium and protein upfront rather than just fat.

The live-arrival guarantee applies to shipping via Ground Advantage, but summer temperatures above 90°F can still cause losses. Storing the bag in the fridge slows growth and keeps the worms dormant for weeks. Multiple reviewers successfully matured these worms into beetles and established self-sustaining colonies, which eliminates the need for repeat orders entirely.

Bassett’s Cricket Ranch is a well-established supplier with consistent quality — the only recurring complaint is worm size being slightly smaller than expected, though most still class them as large. For keepers who want reliability and volume, this is the most premium bulk option.

Superworms are thicker and higher in protein than standard mealworms, making them an ideal prey item for larger jumping spider species like Phidippus regius or Phidippus audax. This 300-count bag from Superworm is organic and raised in Florida — a region with warm conditions that tend to produce more active and robust worms. Reviewers repeatedly praised the “chunky” size and the fact that all 300 arrived alive with zero foul odor.

The worms stayed active for over 25 days when kept with vegetable scraps, which is a strong indicator of good health at the source. One disgruntled customer reported receiving only 50 worms out of 300, but the overwhelming majority of verified purchases reported the full count and excellent condition. Compared to the Bassett bag, this is a smaller count but a larger individual worm size — better for keepers who only have one or two spiders and want to avoid overstock.

Because superworms are slightly more aggressive than mealworms, offer them one at a time and supervise feeding to ensure your spider isn’t overwhelmed. For a large adult jumper, this is a premium protein source that supports muscle tone and active hunting behavior.

This 500-count bag positions itself as a “giant” mealworm option, and many customers confirm the worms are indeed large — suitable for adult jumpers that need a substantial meal. The price per worm is very competitive for the mid-range tier, and the bag is an appropriate size for keepers with two to three spiders who don’t want to store hundreds of worms for weeks. Most reviews mention the worms arrive alive and healthy with no casualties.

The most consistent complaint is inconsistency in worm size — some batches are described as “small to medium” rather than giant, and a few worms may be starting metamorphosis into beetles. One long-time customer with 37+ orders reported a drastic drop in quality and poor customer service when they tried to address the issue. If you order this, check the bag immediately upon arrival and contact the seller for refunds if the size is off.

For keepers who prefer a moderate-volume purchase that still offers large worms at a fair price, this is a solid mid-range pick. Just be prepared for some variability between batches.

Predator Foods is a US-based grower that specializes in organic mealworms, and this 1,250-count bag is one of the most reliable mid-range options for jumping spider keepers. The worms measure approximately 0.75 inches — a good size for subadult to adult jumpers. They are packed in cloth bags, which offer better breathability than plastic bags and significantly reduce moisture buildup and mold risk during shipping.

Customers consistently report fast delivery and zero dead worms. The supplier’s live-arrival guarantee explicitly covers temperatures between 40°F and 80°F, so ordering during spring or fall is recommended. The mealworms are described as “odorless” upon arrival and can be kept in the refrigerator for weeks without issues. Many repeat buyers mention using them for fence lizards and bearded dragons, which suggests the worms are robust enough for a variety of insectivores.

The main downside is that “large” can be inconsistent — some reviews note the worms are on the smaller side of the 0.75-inch mark. For keepers who want organic, healthy feeders at a competitive per-worm price, this is a well-rounded choice.

Surmen Legacy offers 1,000 gut-loaded mealworms at a very low entry point, making this the most budget-friendly option for keepers who need bulk feeders without spending premium dollars. The worms measure between 3/4 and 1 inch, which is appropriate for adult jumpers. The supplier guarantees 100% live delivery, and the overwhelming majority of verified reviews confirm that the worms arrive without a single dead one.

Multiple customers noted that the worms are “very very small” — some felt the count was closer to 800-900 than the advertised 1,000. This is a common issue with bulk mealworm shipments where tiny worms are counted loosely by volume rather than individually. For slings or very small jumpers, this small size is actually a benefit. For keepers expecting large worms, the discrepancy can be disappointing.

Where Surmen Legacy shines is survivability: zero dead worms across multiple orders is the norm, not the exception. If you’re on a tight budget and need a reliable starter supply, this bag delivers. Just don’t expect giant worms at this price point.
