What Do House Spiders Eat When There Are No Flies available? House spiders primarily consume insects, so when flies are scarce, they adapt by preying on other available insects such as ants, mosquitoes, moths, and even smaller spiders. Flyermedia.net is your go-to resource for understanding the fascinating world of arachnids and keeping your home pest-free with expert insights into their dietary habits. By learning about their alternative food sources, you can implement targeted pest control strategies.
1. Identifying Common House Spiders
Before diving into their dietary habits, it’s helpful to know which spiders you’re likely to encounter. Common house spiders include:
- American House Spider (Parasteatoda tepidariorum): This is one of the most common house spiders in the United States. They are known for their messy webs.
- Cellar Spiders (Pholcus phalangioides): Also known as “daddy long-legs,” these spiders prefer damp places like basements and cellars.
- Hobo Spiders (Eratigena agrestis): These spiders are often found in the Pacific Northwest and are known for their funnel-shaped webs.
- Wolf Spiders (Lycosidae): These are hunting spiders that don’t build webs but actively chase their prey.
- Jumping Spiders (Salticidae): Known for their impressive jumping abilities, these spiders are often seen during the day.

These spiders play a role in your home’s ecosystem, often preying on unwanted pests.
1.1. Distinguishing Harmless From Harmful Spiders
Most house spiders are harmless to humans, but it’s crucial to identify potentially dangerous species. Black Widows and Brown Recluses are two venomous spiders found in the United States. Knowing how to identify these spiders and seeking medical attention if bitten is essential for your safety. According to the Centers for Disease Control and Prevention (CDC), spider bites are rarely deadly, but medical care should be sought if symptoms such as severe pain, breathing difficulties, or a spreading ulcer develop.
2. What Do House Spiders Typically Eat?
House spiders are primarily carnivores with a diet consisting mainly of insects. Their typical prey includes:
- Flies
- Mosquitoes
- Moths
- Ants
- Cockroaches
- Earwigs
- Fleas
Spiders play a crucial role in controlling these insect populations within our homes.
2.1. The Role of Webs in Capturing Prey
Many house spiders use webs to capture their prey. These webs are strategically placed to trap flying and crawling insects. The spider waits patiently until an insect gets caught, then quickly immobilizes it with venom.
2.2. Hunting Strategies of Different Spider Species
Not all spiders use webs. Some species, like Wolf Spiders and Jumping Spiders, are active hunters. They rely on their speed and agility to chase down and capture their prey. These hunting spiders often have excellent eyesight, which helps them locate and stalk their targets.
3. What Do House Spiders Eat When Flies Are Not Available?
When their favorite food source, flies, are scarce, house spiders are adaptable and will consume other available insects. Their diet can include:
- Other Insects: Spiders will eat almost any insect they can catch, including ants, beetles, and smaller spiders.
- Small Invertebrates: Some spiders may also feed on other small invertebrates like mites or springtails.
- Leftover Food: Spiders may consume leftover food.
- Cannibalism: In extreme cases, spiders may even resort to cannibalism, preying on other spiders, especially smaller ones.
This adaptability ensures their survival even when their primary food source is limited.
3.1. How Spiders Adapt to Food Scarcity
Spiders have several adaptations that allow them to survive periods of food scarcity:
- Slowed Metabolism: Spiders can slow down their metabolism, reducing their energy needs. This allows them to survive for extended periods without food.
- Fat Storage: Some spiders store fat reserves, which they can use as energy when food is scarce.
- Reduced Activity: Spiders may become less active, conserving energy until food becomes available.
These adaptations help spiders survive in environments where food is not always readily available.
4. The Spider’s Digestive Process
Spiders have a unique digestive process. They inject venom into their prey, which contains enzymes that break down the insect’s tissues. The spider then sucks up the liquefied remains. This process allows them to consume prey much larger than themselves.
4.1. How Spiders Liquefy Their Prey
The venom injected by spiders contains powerful enzymes that break down proteins and other organic molecules. This process turns the insect’s insides into a liquid, which the spider can then easily ingest.
4.2. What Happens to the Exoskeleton?
After consuming the liquefied insides of their prey, spiders leave behind the exoskeleton. These exoskeletons are often found in spider webs or near where spiders have been feeding.
5. How Often Do House Spiders Eat?
Spiders don’t need to eat frequently. They can survive for weeks or even months without food, depending on the species and environmental conditions. However, when food is available, they will eat as much as they can to store energy.
5.1. Factors Affecting Spider Feeding Frequency
Several factors can affect how often a spider eats:
- Availability of Prey: The more prey available, the more often a spider will eat.
- Spider Size: Larger spiders need more food than smaller spiders.
- Metabolic Rate: Spiders with higher metabolic rates need to eat more frequently.
- Environmental Conditions: Spiders may eat more during warmer months when they are more active.
Understanding these factors can help you predict spider behavior in your home.
5.2. Can Spiders Survive Without Water?
While spiders primarily get moisture from their food, they also need water to survive. They can drink small droplets of water or absorb moisture from the air. If spiders go without food for extended periods, water becomes even more critical for their survival.
6. Creating a Spider-Unfriendly Environment
To keep spiders out of your home, it’s essential to eliminate their food sources and create an environment that is less attractive to them.
6.1. Eliminating Food Sources
The best way to keep spiders away is to get rid of the insects they eat. Here are some tips:
- Keep Your Home Clean: Clean up food scraps and spills immediately.
- Store Food Properly: Store food in airtight containers.
- Control Insect Populations: Use natural pest control methods to reduce insect populations in and around your home.
By reducing the number of insects in your home, you’ll make it less attractive to spiders.
6.2. Sealing Entry Points
Spiders can enter your home through cracks and openings in walls, windows, and doors. Sealing these entry points can help keep them out.
6.3. Reducing Clutter
Spiders like to hide in dark, cluttered areas. Reducing clutter can make your home less attractive to them.

- Essential Oils: Peppermint, eucalyptus, and tea tree oil are known to repel spiders.
- Vinegar: Spraying vinegar around your home can deter spiders.
- Diatomaceous Earth: This natural powder can kill insects and spiders by dehydrating them.
These natural methods are safe and effective for keeping spiders out of your home.
7. Common Spider Myths Debunked
There are many myths about spiders. Let’s debunk some of the most common ones:
7.1. Myth: Spiders Always Come Indoors in the Fall

7.2. Myth: All Spiders are Dangerous
Most house spiders are harmless to humans. Only a few species have venom that is dangerous to humans.

7.4. Myth: Spiders Can’t Survive Indoors
Some species of spiders have evolved to spend their entire lives indoors. They are well-adapted to living in human environments. According to the Burke Museum, these spiders thrive in the stable conditions provided by our homes.
8. How to Identify a Spider Bite
Although spiders don’t bite as often as you might think, it’s still essential to know how to identify a spider bite.
8.1. Common Symptoms of Spider Bites
The symptoms of a spider bite can vary depending on the species of spider. Common symptoms include:
