- Cost: Moderately priced for the insect itself, but setup is cheap.

Why Choose a Horrid King Assassin Bug?
If you want a pet that looks like a mini-monster, moves with sinister grace, and has hunting skills straight out of a horror film, this is the insect for you. Unlike traditional pets, the Horrid King Assassin Bug is mesmerizing to watch but not cuddly.
Who Should Get One?
- Invertebrate enthusiasts who want a visually striking pet.
- Predator keepers who enjoy observing hunting behaviors.
- Experienced bug owners who understand venomous species.
Who Should Avoid One?
- Beginners who arenāt comfortable with venomous bites.
- Households with small children (due to handling risks).
- Those who prefer interactive pets (these are display animals).
Handling and Temperament
Not a Pet You “Handle” (And Hereās Why)
The Horrid King Assassin Bug is not a hands-on pet. While some insects tolerate handling, this species is armed with multiple defenses:
- Venomous Bite ā Their needle-like mouthparts (rostrum) can deliver a painful stab with venom that causes swelling and discomfort.
- Chemical Spray ā Some assassin bugs can spray defensive chemicals, irritating skin and eyes.
- Spiky Armor ā Their pronotum (thorax shield) is covered in sharp spines, making them difficult to hold safely.
Can You Hold Them? (Technically⦠Yes, But Should You?)
While some experienced keepers briefly handle them, itās not recommended. If you must move them, use soft paintbrushes or coax them into a container.
Key Handling Tips:
- Never grab them from above (risk of triggering a bite).
- Avoid sudden movements (they can be skittish).
- Wash hands after contact (in case of chemical residue).
Bottom Line: These bugs are best admired from behind glass.
Care and Maintenance
Surprisingly Simple for Such a Fierce Predator
Despite their intimidating appearance, Horrid King Assassin Bugs are low-maintenance compared to many reptiles or mammals.
Enclosure Setup
- Size: A 10-gallon tank is perfect for a small group.
- Climbing Space: Theyāre arboreal, so provide cork bark, branches, and egg crates for vertical movement.
- Substrate: Paper towels or dry bioactive soil (avoid excessive moisture).
- Hiding Spots: Leaf litter or fake plants help them feel secure.
Humidity & Temperature
- Humidity: 50-70% (mist lightly every few days).
- Temperature: 75-85°F (24-29°C)āroom temp is usually fine.
Feeding (The Gruesome Part)
- Diet: Live insects only (crickets, roaches, mealworms).
- Frequency: Feed adults 2-3 times a week; nymphs more often.
- Hunting Style: They ambush prey, stab it, and suck out the liquefied insides.
Pro Tip: Remove uneaten prey to avoid stress.

Health and Durability
A Hardy Insect (If You Avoid These Mistakes)
Horrid King Assassin Bugs are resilient, but improper care can lead to issues:
- Molting Problems: If they canāt hang upside-down, they may die during molting.
- Dehydration: Too-low humidity can cause failed molts.
- Overcrowding: Cannibalism can occur if kept in tight spaces.
Lifespan: 1-2 years (longer than many insects).
Availability and Cost
Not in Pet Stores (But Worth the Hunt)
These bugs are rare in chain pet stores but available from:
- Specialty breeders
- Insect expos
- Online invertebrate shops
Pricing
- Individual Bug: $20 to $50 (rarer color morphs cost more).
