Our Farm
Clean, controlled indoor environment in Eugene, Oregon — free from pesticides and harmful chemicals. We typically do not ship wheat bran with the mealworms. In colder weather, we include a small amount as insulation and to give the mealworms a food source — their digestion generates a bit of metabolic heat, which helps them stay warm in transit.

Temperature Holds — When We Can't Ship
?️ Extreme Heat Hold
90°F +
We will not ship if temperatures at our facility in Eugene, OR or at your delivery location are forecast to reach 90°F or above. Heat is the fastest way to kill live mealworms in transit, and we'd rather delay your order than deliver a dead one.
❄️ Freezing Temperature Hold
32°F and below
We will not ship if temperatures at our facility in Eugene, OR or at your delivery location are forecast to drop to freezing or below. Mealworms cannot survive being frozen in transit.
What happens to my order during a hold? We'll hold your order and ship it on the next safe shipping day. You don't need to do anything — we monitor forecasts daily and will reach out if an extended delay is expected.
Contact us if you have questions about a pending order.

Once you receive your mealworms, place them in a container with wheat bran or rolled oats for bedding. Add a few thin slices of raw potato or carrot on top to keep them hydrated. Then refrigerate at 45–50°F (7–10°C) — this slows their metabolism, keeping them in the larval stage and preventing them from pupating into beetles.
To keep your mealworms in "Maintenance Mode" — alive and healthy, but not growing — you need to slow their metabolism with cold. Choose the option that fits your setup:
Option A
The Dedicated Fridge
Ideal for wine coolers, dorm fridges, or a secondary garage fridge where you control the temp exclusively.
- Sweet Spot: Set to 45°F – 50°F (7–10°C) — the perfect hibernation range.
- Placement: Anywhere in the fridge works.
✅ Up to 2–3 months
Option B
The Standard Household Fridge
Ideal for most customers using their primary kitchen refrigerator (typically set to 37–38°F for food safety).
- Warmer spots: Store in the door or top shelf — 3–5°F warmer than the back.
- Insulate: Wrap container in a small towel to buffer cold air blasts.
- Weekly wakes: Take out once a week to warm up and hydrate.
⏱ Up to 2–3 weeks
Even in the fridge, mealworms need a drink once a week to stay alive and healthy. These four steps take about 5 minutes:
1
Warm Up
Remove from fridge, let sit at room temperature for 1–2 hours until they start moving.
2
Hydrate
Lay a few thin slices of potato or carrot on top of the bedding.
3
Feed
Let them eat and drink for 3–4 hours undisturbed.
4
Clean Up
Remove all uneaten potato (prevents mold), then return to fridge.
Note on Bedding: You do not need to change the wheat bran regularly. Only replace it if it starts to look like fine sandy dust (waste) or smells damp. For most customers, the original bedding lasts the entire life of the batch.
Protect your mealworms from the elements so they stay alive and appealing to birds:
☀️ Warm Weather Keep the feeder and worms in the shade. Direct sunlight can kill them quickly.
❄️ Cold Weather Below 40°F, mealworms may freeze. Add bedding for insulation to protect them in the feeder.
Feeding Bluebirds specifically? Stray wheat bran or grain in your feeder can attract House Sparrows and other bully birds. To keep your feeder clean and your bluebirds safe, sift the mealworms to separate them from their bedding using a handheld sifter with a 1/8-inch (3 mm) opening.
