Spiders don’t need a lot of food to survive. However, when there is a large amount available, they will feed in large quantities. In addition, some spiders can survive several days without eating at all. Some species even live off human food, such as egg yolk, sausage, and marmalade. One species is a true herbivore, meaning it feeds primarily on plant material.

Crickets
Many people may be surprised to learn that crickets can be fed to spiders. Although spiders aren’t the only creatures that enjoy insects, they do have a unique relationship with them. In a recent study, researchers showed that the exposure of mother crickets to spiders altered their offspring’s behavior. They found that offspring of mothers who had been around spiders were more cautious and likely to survive when faced with the same predators.
Crickets can be found almost anywhere. They are much smaller than other insects and are ideal for all types of spiders. They should only be smaller than the spiders’ size because if they’re too big for the spider, they may not be as active as they could be.
Fruit flies
Spiders feed on a variety of insects, including fruit flies, and it’s no surprise. However, fruit flies vary in fat content. Some species have only a few percent lipids, whereas others contain as much as three percent. These insects are often fed to spiders as a supplement to their diets.
Flightless fruit flies are a great food for small spiders, and they’re easy to find at pet stores or online distributors. You can also culture your own fruit flies at home. One culture will yield several, so don’t be shy about getting started with a new food source. However, fruit flies should never be the primary source of food for larger spider species.
Bottle flies
There are a variety of ways to feed bottle flies to spiders. These insects are flightless and can be purchased at most pet stores or online distributors. They are a great alternative for feeding smaller species, but should not be the primary source of food for larger species.
The green bottle fly is not a threat to humans, but is a nuisance pest. It feeds on dead animals, sewage, and garbage. Because of this, it may carry pathogenic bacteria. It may also infest food in your home. In addition, fly larvae can infest unbroken skin and human tissues. Eventually, these flies can cause severe irritation or even be fatal.
Mosquitoes
When you’re looking for something to feed your spiders, you’re going to want to choose something that will appeal to them. While most spiders don’t eat humans, they do eat insects. Spiders can be quite dangerous because they can inject venom. This venom is made by spiders in their salivary glands and delivered through hollow, pointed bits on the end of their legs. Spider venom is mostly toxic to arthropods, their main prey.
If you’re looking for a cheaper option, crickets are a great choice. Crickets are easy to find and can be fed to spiders of all sizes. Larger species can eat up to eight crickets per week, and smaller species can eat as few as one.
Bees
It is believed that spiders do not eat insects but instead suck the “juices” from them. In fact, some scientists believe that spiders are tiny vampires! Despite this misconception, all spider species digest solid parts of their prey. This digestion begins outside the spider and continues inside.
While many species of spiders do not attack humans, they do eat valuable pollinators. While crab spiders don’t recognize valuable pollinators, many bees have keen senses. This means that a crab spider can only fool them if the UV light emitted by the flower matches its own color. As a result, the presence of crab spiders can lead to a drop in pollination rates. Of course, the drop-off rate depends on the type of flowers and the number of spiders.
Fly larvae
Fly larvae are easily available at most pet stores and online distributors, and they are excellent feeders for jumping spiders. You can also buy them cheaply from anglers. The smallest species that are sold for food are D.melanogaster, which is also commonly used to feed the Phidippus hatchling. Because of their short lifespan, fly larvae make a convenient option for feeding your spiders.
The nutritional composition of fly larvae is dependent on how they are raised. Usually, they are fed moistened chicken feed. The high-quality ones, however, have been raised on a specially-formulated grain and grass diet, and may even have calcium added.
Insects
House spiders do not need a lot of food and can go for weeks without eating. However, when they find the right insects to feed on, they will usually eat several times a day. Ideally, you should feed them once or twice a week. To avoid accidentally overfeeding them, make sure to carefully seal the container. If you do not have any insects around your home, you can purchase insects from a pet store.
The best way to feed spiders is to give them some types of plant matter. Fruit is not recommended as it doesn’t have the same nutrients that spiders need. Also, avoid feeding your spiders dead animals, as they also feed on dead insects.
