Equipment List

Before you ever bring an invertebrate home, you need the right equipment already in place and ready to go. This is not something you can figure out on the fly, because a tarantula sitting in a deli cup on your kitchen counter while you run out for substrate and a hygrometer is not a great start for either of you. Having the correct tools and supplies on hand means the animal goes straight into a properly configured enclosure, and that first impression of a stable, comfortable environment sets the tone for everything that follows.

Every invertebrate keeper regardless of experience level relies on a core set of equipment that covers enclosure construction, environmental monitoring, feeding, cleaning, and maintenance. The specifics change depending on what you keep, but the categories remain consistent whether you are housing a single pet tarantula or managing shelves of breeding colonies. A desert scorpion keeper and a tropical millipede keeper buy different substrates and aim for different humidity levels, but both need reliable thermometers, appropriate enclosures, and tools for safe animal handling.

Getting your equipment sorted before the animal arrives prevents the scramble that leads to improvised solutions and compromised husbandry. Makeshift setups tend to become permanent because once an animal is housed, the motivation to rebuild drops significantly. Starting with the right gear means you are not retrofitting problems six months later when mold has taken over a poorly ventilated enclosure or your thermometer turns out to be wildly inaccurate.

New keepers often ask what the bare minimum is, and while that question is understandable from a budget perspective, the better question is what equipment gives you the best chance of keeping your animal healthy with the least ongoing hassle. Cheap tools fail, inaccurate instruments give you false confidence, and flimsy enclosures create escape risks. Spending a little more upfront on reliable equipment saves money and stress over time.

This article walks through the essential equipment categories every invertebrate keeper should have, explains what each tool does and why it matters, covers how needs differ across species groups, and helps you avoid the purchasing mistakes that waste money or compromise your animals.

The foundation of your equipment list starts with enclosures themselves. Glass terrariums, acrylic containers, plastic storage bins, and deli cups all serve different purposes depending on the species, its size, and its life stage. Glass offers excellent visibility and holds humidity well but is heavy and expensive in larger sizes. Acrylic is lighter and easier to modify with ventilation holes but scratches over time. Plastic containers from hardware stores work perfectly for many species and cost a fraction of commercial terrariums. The right enclosure is the one that provides appropriate dimensions, ventilation, and security for your specific animal.

Environmental monitoring equipment is not optional. You need at minimum a reliable digital thermometer and a hygrometer to track temperature and humidity inside each enclosure. Analog dial gauges are notoriously inaccurate and should be avoided entirely. Digital probe thermometers that let you place the sensor inside the enclosure while reading the display outside are ideal. For humidity-dependent species like tropical tarantulas, millipedes, and hermit crabs, a hygrometer with reasonable accuracy within five percent is essential for preventing dehydration or overly damp conditions that promote mold.

Heating equipment varies by species and room conditions. Many tropical invertebrates need supplemental heat, and the standard approach is a low-wattage heat mat placed on the side or back of the enclosure rather than underneath where it can dry out substrate. Heat mats should always be used with a thermostat, not run unregulated. An uncontrolled heat mat can easily overheat a small enclosure and kill the occupant. Proportional thermostats offer the most stable control, but even a basic on-off thermostat is far better than none.

Feeding and watering tools include long forceps or tongs for offering prey items, shallow water dishes that prevent drowning, and spray bottles for misting enclosures. Forceps in the ten to twelve inch range keep your fingers safely away from defensive species while allowing precise prey placement. Water dishes should be shallow enough that even small invertebrates can climb out, and placing pebbles or mesh in deeper dishes provides escape routes for any feeder insects that fall in.

Cleaning and maintenance equipment covers the tools you use week after week to keep enclosures healthy. Small scoops or spoons for spot cleaning waste, paper towels for wiping glass, small brushes for removing webbing when needed, and extra containers for temporarily housing animals during deep cleans all belong in your supply kit. A dedicated set of cleaning tools that you use only for your enclosures prevents cross-contamination from household chemicals.

Beyond the basics, experienced keepers accumulate specialty equipment that makes management easier. Catch cups and cardboard for safe rehousing, magnifying lenses for examining small specimens, small digital scales for tracking growth, and label makers or tape for keeping enclosures properly identified all improve your operation as your collection grows. None of these are critical for a single pet, but they become increasingly valuable as you add animals.

Arachnid keepers need equipment tailored to whether their species is terrestrial, arboreal, or fossorial. Terrestrial tarantulas require enclosures with more floor space than height and deep substrate for burrowing species. Arboreal species need tall enclosures with cross-ventilation and vertical climbing surfaces like cork bark tubes. Scorpion keepers working with desert species need reliable thermometers and heat mats, while tropical forest scorpions need humidity monitoring equipment similar to what tropical tarantula keepers use. Long forceps are particularly important for scorpion feeding since many species are fast and defensive during prey capture.

Insect keepers face different equipment priorities depending on the order. Praying mantis enclosures prioritize height and ventilation with mesh or screen lids that allow proper airflow while preventing escape through surprisingly small gaps. Stick insect keepers need tall containers with branches and fresh plant material, plus spray bottles for the regular misting most species require. Beetle keepers housing species with larval stages need deep containers with specific substrate blends, and the equipment list expands to include substrate mixing tools and containers for managing different life stages separately.

Myriapod keepers need enclosures that prioritize depth over height, since both millipedes and centipedes spend most of their time in or on substrate. Millipede setups require deep organic substrate that the animals actually consume, making substrate preparation tools like mixing containers and moisture testing equipment important. Centipede keepers need escape-proof enclosures above all else, because a fast centipede that gets out of its container is a genuinely difficult animal to recapture safely. Locking lids and sealed ventilation holes are not optional for centipede enclosures.

Crustacean and mollusk keepers often need aquatic or semi-aquatic equipment that terrestrial keepers never touch. Hermit crab keepers need both freshwater and saltwater dishes, humidity gauges, and heating equipment to maintain tropical conditions. Aquatic invertebrate keepers housing shrimp or crayfish need filtration systems, water testing kits for parameters like pH and ammonia, airline tubing, and siphons for water changes. Snail keepers need shallow water features, calcium supplements, and enclosures with secure lids since many snail species are surprisingly strong climbers.

Across all groups, the universal equipment principles remain consistent. You need a way to monitor conditions, a way to maintain conditions, tools for safe feeding and cleaning, and containers appropriate for your specific species. The exact products change, but the categories do not.

Before buying anything, make a list based on the specific species you plan to keep. Research that species first, identify its enclosure type, temperature range, humidity needs, and diet, then work backward to determine what equipment those requirements demand. This prevents buying a beautiful glass terrarium only to discover your fossorial tarantula needs a deep plastic container instead, or purchasing a misting system when your desert species actually needs dry conditions.

Buy your equipment and set everything up at least a few days before the animal arrives. This gives you time to verify that your thermometer reads accurately by comparing it against a known reference, confirm that your heat mat with thermostat holds a stable temperature, and ensure your enclosure retains or releases humidity at the rate your species requires. Running the setup empty for a couple of days reveals problems like excessive heat buildup or humidity that crashes overnight, both of which are much easier to fix without an animal in residence.

For day-to-day maintenance, keep your most-used tools organized and accessible near your enclosures. Forceps, spray bottles, a thermometer for spot checks, and paper towels should be within arm's reach during routine care. If you find yourself skipping maintenance because your tools are stored in another room, the solution is better organization, not less maintenance. A small caddy or dedicated shelf near your enclosure rack keeps everything where you need it.

When equipment fails, and it will eventually, have backup plans ready. A spare heat mat, an extra thermometer, and a couple of appropriately sized backup containers can prevent an equipment failure from becoming an animal emergency. Heat mats are the most common failure point, and losing heat during cold weather can stress or kill tropical species overnight. Keeping a spare is cheap insurance.

As your collection grows, standardizing equipment across enclosures saves time and money. Using the same size containers, the same type of water dishes, and the same substrate within species groups means you can buy in bulk and swap components easily. Standardization also makes your maintenance routine faster because you are not adapting your approach to a dozen different enclosure configurations every time you do weekly care.

The most common equipment mistake new keepers make is buying the enclosure based on how it looks rather than whether it meets the species requirements. A beautifully planted glass terrarium with a screen top looks fantastic on a shelf, but for a humidity-dependent tropical species that setup will lose moisture constantly through the screen and require misting multiple times daily just to maintain adequate levels. Meanwhile a modified plastic container with small ventilation holes drilled in the sides holds humidity effortlessly and costs a tenth as much. Choose function first and aesthetics second.

Running heat mats without a thermostat is a mistake that kills animals. It seems like a small heat mat could not possibly overheat a container, but it absolutely can, especially in smaller enclosures during warm weather. The surface temperature of an unregulated heat mat can reach well above what any invertebrate can tolerate. A thermostat costs roughly the same as replacing a dead animal, and there is no reason to skip it. Plug the heat mat into a thermostat, set your target temperature, and let the controller do its job.

Relying on inaccurate instruments gives you false confidence about your conditions. Cheap analog dial hygrometers are frequently off by twenty percent or more, which means you could think your humidity is at seventy percent when it is actually at fifty. Your animal does not care what your gauge says. It responds to actual conditions. Invest in digital instruments from reputable sources, and periodically verify their accuracy by testing them in a controlled environment.

Buying everything at once without knowing your specific needs leads to wasted money and unused equipment sitting in a drawer. New keepers sometimes buy elaborate misting systems, lighting rigs, and commercial substrate blends before understanding that their particular species thrives in a simple setup with damp coconut fiber and a water dish. Research the species first, understand what it actually needs, and buy accordingly. You can always add equipment later if your keeping evolves.

Neglecting to maintain your equipment is just as problematic as not having it. Spray bottles clog, thermometer batteries die, heat mats degrade over time, and hygrometers drift out of calibration. Build equipment checks into your regular maintenance routine. When you do your weekly enclosure maintenance, take thirty seconds to verify that your instruments are reading correctly and your heating equipment is functioning as expected. Catching a failing heat mat before it dies completely is much better than discovering it on a cold morning.

Your equipment is the infrastructure that makes proper husbandry possible. The enclosure provides shelter, instruments tell you what conditions actually exist inside it, heating maintains appropriate temperatures, and your feeding and cleaning tools let you manage the environment safely week after week. None of this is glamorous, but all of it is essential. An animal in a well-equipped enclosure with accurate monitoring has fundamentally better odds than one in a nice-looking setup where nobody actually knows the temperature or humidity.

Think of equipment as preventive care. A reliable thermostat prevents overheating deaths. An accurate hygrometer prevents dehydration or mold problems. Proper forceps prevent defensive bites during feeding. Secure lids prevent escapes. Every piece of functional equipment in your setup is quietly preventing a problem that would otherwise eventually find you. The money you spend on good tools pays for itself in animals that stay healthy and enclosures that stay stable.

Research your species before building your equipment list, because the requirements vary enormously across invertebrate groups. What works perfectly for a desert hairy scorpion would be dangerously wrong for a tropical millipede. General equipment guides like this one give you the categories and principles, but the specific products and configurations come from understanding what your particular animal needs. Species-specific care sheets from experienced keepers are worth their weight in gold for dialing in exactly what to buy.

Start with the essentials, buy quality where it counts, and add specialty items as your experience and collection grow. You do not need every piece of equipment on day one, but you absolutely need the right enclosure, accurate monitoring instruments, appropriate heating if your species requires it, and basic feeding and cleaning tools. Get those right and you have a solid foundation that serves both you and your animals well for years. The keepers who enjoy this hobby the most are the ones whose equipment works reliably so they can focus on actually observing and appreciating their animals rather than constantly troubleshooting failing gear.
