If you’re looking for an uncommon yet fascinating pet, consider the Madagascar Hissing Cockroach, or Gromphadorhina portentosa. Far from your average household pest, these are large, calm, unconventional pet insects that are super easy to care for and can be kept together in colonies. These cockroaches are primarily herbivores and thrive on a diet of fresh fruits and vegetables. They particularly enjoy apples, oranges, and lettuce, but they’re not too fussy. Protein can be introduced in the form of dried insects. They also require a source of water, which can be easily provided through a shallow dish or regular misting of their enclosure. A 10-gallon tank should suffice for a small colony. The substrate can be made up of peat moss or coco fibre, allowing the cockroaches to burrow. Pieces of bark can also be added for additional hiding spots, along with live or artificial plants. Madagascar Hissing Cockroaches are most comfortable at temperatures between 75-90°F (24-32°C). They can tolerate lower humidity levels but aim to maintain around 60-70% humidity for optimal health.

One of the standout features of this cockroach species is the distinct hissing sound they make, which is used for communication and as a defence mechanism. Unlike other insects, they produce this sound by forcing air through their respiratory openings, making them one of the few insects capable of ‘vocalising’.

Ordering pets online can be nerve-wracking, we get it. Our 7-Day live guarantee is our way to ease nerves over the purchasing process.

We’re confident in the quality husbandry, shipping, and packaging of our livestock. On the rare occasion an animal arrives in poor condition, we will provide credit for the cost of that animal. If all animals in the shipment arrive in poor condition, we will also provide credit for the postage.

We try to make it as easy as possible to help any unwell critters, and ensure you can get your money back. There are a couple of steps to go through before a refund can be issued.

If you’ve received an unwell animal in the mail:

1. If it is safe to do so, (your pet is not medically significant or harmful) please remove the animal from its transport container, ideally onto your hand. We ask this as invertebrates, particularly insects, are experts at ‘playing dead’.

2. To provide you with the best advice going forward and to confirm the condition of your pet, we kindly request a short video of the animal in question before your refund can be processed. This can be uploaded on our ‘live guarantee refunds form’, or you can email it straight to us.

3. We typically respond within 24 hours, but please allow 1-3 working days for a response. Once it’s confirmed that you are eligible for a refund, we’ll get process the credit to your account.

We’ll need this information to reach us within 7 days after you’ve received your pet. We cannot provide any live guarantee to animals that have been refused, returned, or not collected.
