Drop in a bug, spider eats it, end of story. In practice, feeder choice influences safety, nutrition, stress levels, enclosure hygiene, and long-term success. This article goes deep into the most commonly used feeders in the tarantula hobby, how big they are at different life stages, what makes them useful or problematic, and how to handle those problems intelligently.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Two Golden Rules<\/h2>\n\n\n\n<p>Before diving into individual feeders, one guideline applies almost universally:<\/p>\n\n\n\n<p><strong>A feeder should not be larger than the tarantula\u2019s body length.<\/strong><\/p>\n\n\n\n<p>The second, and arguably most important guideline is:<\/p>\n\n\n\n<p><strong>NEVER feed wild caught animals!<\/strong><\/p>\n\n\n\n<p>Wild caught animals can be contaminated with pesticides or be infected with parasites. If you do not follow this guideline, you are risking your tarantulas health.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Crickets (Acheta and Gryllus species)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Size and Development<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Pinhead crickets:<\/strong> ~2\u20133 mm (0.08\u20130.12 in)<\/li>\n\n\n\n<li><strong>Small crickets:<\/strong> ~6\u201310 mm (0.25\u20130.4 in)<\/li>\n\n\n\n<li><strong>Medium crickets:<\/strong> ~12\u201320 mm (0.5\u20130.8 in)<\/li>\n\n\n\n<li><strong>Adult crickets:<\/strong> ~25\u201330 mm (1\u20131.2 in)<\/li>\n<\/ul>\n\n\n\n<p>Crickets grow through multiple instars, molting frequently until adulthood.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages<\/h3>\n\n\n\n<p>Crickets are extremely sensitive to vibration and movement, they feel a tarantula approaching. This makes them ideal for triggering feeding responses. They are also widely available and inexpensive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Disadvantages and Why They Exist<\/h3>\n\n\n\n<p>Crickets smell because they produce ammonia-rich waste in poorly ventilated containers. They are noisy because males <a href=\".\/tarantula-glossary\/#gloss01_stridulation\" target=\"_blank\">stridulate <\/a>to attract females. More importantly, crickets are opportunistic omnivores. In nature, they scavenge anything edible, including soft tissue. This is why crickets may chew on a tarantula during <a href=\".\/tarantula-glossary\/#gloss01_molt\" target=\"_blank\">molting<\/a>. A freshly molted spider is soft, immobile, and vulnerable.<\/p>\n\n\n\n<p>Pinhead crickets and small crickets are also very difficult to pick up with tongs, as they are quite fast and small.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to Mitigate the Risks<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Remove uneaten crickets after 24 hours.<\/li>\n\n\n\n<li>Never leave crickets with a molting tarantula.<\/li>\n\n\n\n<li>Crushing the head disables the mandibles while preserving movement.<\/li>\n<\/ul>\n\n\n<div class=\"nf-joke flex flex-cols gap-2 p-2 my-4 border-l-4 border-emerald-500 bg-gray-100 rounded-md shadow-sm\">\n        <img decoding=\"async\" class=\"relative h-[80px]\" src=\"https:\/\/nocturnalfangs.com\/wp-content\/themes\/nocturnalfangs\/public\/build\/assets\/joke_logo-C7K6FOs1.png\">\n        <div class=\"flex items-center justify-center w-full text-lg\">A tarantula and a cricket walk into a bar.<br \/>\nTarantula: Nice to eat you!<br \/>\nCricket: I beg your pardon?<\/div>\n    <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Worms (Mealworms, Tenebrio molitor)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Size and Development<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Small larvae:<\/strong> ~5\u201310 mm (0.2\u20130.4 in)<\/li>\n\n\n\n<li><strong>Medium larvae:<\/strong> ~15\u201320 mm (0.6\u20130.8 in)<\/li>\n\n\n\n<li><strong>Large larvae:<\/strong> ~25\u201330 mm (1\u20131.2 in)<\/li>\n<\/ul>\n\n\n\n<p>Mealworms are beetle larvae and will pupate if left undisturbed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages<\/h3>\n\n\n\n<p>They are quiet, easy to store at low temperatures, and readily available.

In enclosures with loose <a href=\"#gloss01_substrate\">substrate<\/a>, they can disappear quickly.<\/li>\n\n\n\n<li>Less stimulating movement which can reduce feeding response in very shy or defensive tarantulas.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Preventing Dubia Roaches From Burrowing<\/h3>\n\n\n\n<p>The easiest way to prevent dubia roaches from burrowing is to crush their head with the feeding tongs. Brutal, but effective. Dubias that are pre-killed this way will keep wandering around the enclosure for a while.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Red Runner Roaches (Shelfordella lateralis)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Size and Development<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Nymphs:<\/strong> ~4\u20138 mm (0.16\u20130.3 in)<\/li>\n\n\n\n<li><strong>Adults:<\/strong> ~20\u201325 mm (0.8\u20131.0 in)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Natural Distribution and Habitat<\/h3>\n\n\n\n<p>Native to arid and semi-arid regions of North Africa and the Middle East.

Any rough plastic, silicone seams, or ventilation mesh can become an escape route.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Highly active triggering strong feeding responses even in reluctant tarantulas. In my opinion these roaches are the <strong>most fun<\/strong> feeder to use.<\/li>\n\n\n\n<li>Smaller average size, making them suitable for juveniles and medium-sized species.<\/li>\n\n\n\n<li>Excellent for large collections due to rapid population growth.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Disadvantages<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Can climb textured surfaces increasing escape risk.<\/li>\n\n\n\n<li>More prone to escapes during feeding or maintenance due to their speed and dexterity.

When you&#8217;re ready to feed, take out the egg carton with a bunch of roaches in them and shake them off into an empty plastic container. If you have done this, then your&#8217;re able to angle the container so the roaches collect in a corner, which makes it easier to just pick one up.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Locusts (Schistocerca gregaria)<\/h2>\n\n\n\n<p>Locusts are less commonly used than crickets or roaches, but where available, they can be an excellent feeder. Their size progression makes them suitable for a wide range of tarantulas, from juveniles to large adults.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Size and Development<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Early instars:<\/strong> ~10\u201320 mm (0.4\u20130.8 in)<\/li>\n\n\n\n<li><strong>Mid instars:<\/strong> ~25\u201340 mm (1.0\u20131.6 in)<\/li>\n\n\n\n<li><strong>Late instars:<\/strong> ~45\u201355 mm (1.8\u20132.2 in)<\/li>\n\n\n\n<li><strong>Adults:<\/strong> ~50\u201370 mm (2.0\u20132.8 in)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Natural Habitat and Biology<\/h3>\n\n\n\n<p><em>Schistocerca gregaria<\/em> is native to arid and semi-arid regions of Africa and parts of Asia.

The good thing is that they also feed by scavenging exposed soft tissue.<br>Effective options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A crushed cricket leg<\/li>\n\n\n\n<li>A cut section of mealworm<\/li>\n\n\n\n<li>A pre-killed (half) roach nymph<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Storing Feeder Insects Properly (Short-Term and Medium-Term)<\/h2>\n\n\n\n<p>Not everyone wants to breed feeders, and that is perfectly fine. Many keepers buy feeders as needed, especially when they only keep a handful of tarantulas. In that case, correct storage becomes important, not just to keep the feeders alive, but to keep them healthy and safe to use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Using Store-Bought Containers<\/h3>\n\n\n\n<p>If you buy feeders from a shop or online supplier, you can usually keep them in the container they came in for a short time. These containers are designed for transport and temporary storage, not long-term housing, but they work if you follow a few rules.<\/p>\n\n\n\n<p>Ventilation is key. Most feeder deaths in store containers happen because of stagnant air and moisture buildup. Open the container briefly every day to exchange air. Remove dead insects immediately. Dead feeders decompose quickly and raise ammonia levels, which kills the remaining insects.<\/p>\n\n\n\n<p>Do not overcrowd. If you bought a large quantity, splitting them into two containers dramatically increases survival time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Using a Critter Keeper or Simple Plastic Box<\/h3>\n\n\n\n<p>A small critter keeper or ventilated plastic box works better than most store containers. The reason is simple: more air volume, better ventilation, and easier cleaning.<\/p>\n\n\n\n<p>Add cardboard egg cartons, toilet paper rolls, or similar structures. These increase surface area and reduce stress by giving insects places to hide. Stress directly affects feeder longevity. Stressed insects die faster, smell worse, and gut load poorly.<\/p>\n\n\n\n<p>Avoid substrate for most feeders unless specifically required. Loose substrate traps moisture and waste, which leads to mold and bacterial growth.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Temperature and Storage Logic<\/h3>\n\n\n\n<p>Most feeder insects live longer at slightly cooler temperatures, but not cold. Refrigeration slows metabolism in mealworms, which is why they are often stored cold. Crickets and roaches should be kept at room temperature. Too cold and they die. Too warm and they age faster.<\/p>\n\n\n\n<p>The goal of storage is not growth or reproduction, it is stability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Gut Loading Explained in Practical Terms<\/h3>\n\n\n\n<p><a target=\"_blank\" href=\".\/tarantula-glossary\/#gloss01_gut-loading\">Gut loading<\/a> is often mentioned, but rarely explained properly.<\/p>\n\n\n\n<p>Feeder insects are only as nutritious as what they have eaten recently. A feeder that has been sitting in an empty box for days is nutritionally poor, even if the species itself is considered \u201cgood.\u201d<\/p>\n\n\n\n<p>Gut loading works because tarantulas consume the entire insect, including the contents of its digestive system. Vitamins, minerals, and moisture inside the feeder are transferred directly to the tarantula.<\/p>\n\n\n\n<p>Effective gut loading does not need to be complicated.<\/p>\n\n\n\n<p>Good gut loading options include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fruit jelly cups (easy, clean, vitamin-rich)<\/li>\n\n\n\n<li>Fresh vegetables (carrot, zucchini, leafy greens)<\/li>\n\n\n\n<li>Dry fish food pellets (protein and fats)<\/li>\n<\/ul>\n\n\n\n<p>Avoid citrus, spicy foods, or anything treated with pesticides.<\/p>\n\n\n\n<p>Gut load feeders for at least 24 hours before feeding them off. Longer is fine, but consistency matters more than perfection.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Setting Up Red Runner Roaches as Feeders\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/-mt8wyl89i4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Setting Up Your Own Roach Colony (Dubia and Shelfordella lateralis)<\/h2>\n\n\n\n<p>Breeding your own roaches is one of the most efficient upgrades you can make as a keeper. It lowers long-term cost, guarantees availability, and gives you full control over feeder quality. The setup does not need to be complicated, but it does need to respect roach biology.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Container Choice and Why Smooth Walls Matter<\/h3>\n\n\n\n<p>Use a smooth-walled plastic box with a secure lid. Smooth walls are critical because many roaches rely on tiny hooks and pads on their feet to climb textured surfaces. Smooth plastic offers no grip.<\/p>\n\n\n\n<p>Glass aquariums also work, but plastic is lighter, cheaper, and easier to modify.<\/p>\n\n\n\n<p>Ventilation holes should be small and covered with fine mesh. Roaches need airflow, but escapes happen through surprisingly small gaps.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Substrate or No Substrate?<\/h3>\n\n\n\n<p>Substrate is optional. Many successful colonies run without any substrate at all. I prefer adding a thin layer of substrate. With substrate, maintenance can actually be simpler, since you can remove and replace it entirely instead of scrubbing the container. As long as the substrate is kept dry and not allowed to mold, it does not negatively affect the colony.<\/p>\n\n\n\n<p>If you do use substrate, keep it thin and dry. Excess moisture is the main cause of mold and mite problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hides and Vertical Space<\/h3>\n\n\n\n<p>Egg cartons or cork bark are ideal. Roaches prefer tight, dark spaces with lots of surface contact. Vertical stacking increases usable space and improves airflow.<\/p>\n\n\n\n<p>More surface area equals more roaches per box without stress.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Water: Why Aqua Crystals Work Best<\/h3>\n\n\n\n<p>As a water source, aqua crystals in a shallow plastic dish are ideal. They provide moisture without drowning risk and do not spill easily.<br>Open water dishes increase humidity too much and cause drowning, especially for small nymphs.<br>Replace crystals regularly. Old crystals grow bacteria and mold.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Food: Low Maintenance vs High Maintenance<\/h3>\n\n\n\n<p>For a low-maintenance setup, I recommend:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fruit jelly for vitamins and moisture<\/li>\n\n\n\n<li>Fish feed pellets for protein<\/li>\n<\/ul>\n\n\n\n<p>This combination is clean, long-lasting, and requires minimal daily attention.<br>Fresh vegetables absolutely work, but they require discipline. Vegetables rot quickly, especially in warm environments. Rotting food attracts mold, mites, and flies. If you use fresh vegetables, remove leftovers daily.<\/p>\n\n\n\n<p>Low maintenance setups win in the long run.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Optimal Conditions for Reproduction<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">Dubia Roaches (Blaptica dubia)<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Temperature:<\/strong> 28\u201332 \u00b0C (82\u201390 \u00b0F)<\/li>\n\n\n\n<li><strong>Humidity:<\/strong> Moderate, around 50\u201370 percent<\/li>\n<\/ul>\n\n\n\n<p>Dubia roaches originate from warm, humid environments in Central and South America. In captivity, humidity is often maintained naturally through roach waste, egg cartons, and respiration. You usually do not need to mist.<\/p>\n\n\n\n<p>Warmth is the primary trigger for reproduction. A side-mounted heat pad connected to a thermostat creates a warm zone without overheating the entire container. Roaches move freely to regulate their body temperature.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Shelfordella lateralis (Red Runners)<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Temperature:<\/strong> 30\u201335 \u00b0C (86\u201395 \u00b0F)<\/li>\n\n\n\n<li><strong>Humidity:<\/strong> Low to moderate<\/li>\n<\/ul>\n\n\n\n<p>Lateralis originate from drier, hotter regions. They reproduce extremely fast when warm and do not require elevated humidity. In fact, too much moisture causes die-offs.<br>Because they are more active and faster, secure lids and smooth walls are even more important.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why Heat Pads Should Be Side-Mounted<\/h3>\n\n\n\n<p>Never place heat pads under the container.
