Ever wondered what’s on a spider’s menu? It might surprise you to learn that spiders are nature’s pest control experts. They munch on many insects that might otherwise invade our homes.
About 10 quintillion insects are alive at any given time, making the spider’s job both essential and endless.
So what do spiders eat? Turns out, it kind of depends. Let’s take a closer look.
What Do Spiders Eat?
Some spiders are picky eaters, while others will consume almost anything they can catch.
Most spiders are carnivorous. They primarily feed on insects and other small arthropods. This might include flies, mosquitoes, moths, and beetles.
But that’s not all – some larger spider species can even tackle small vertebrates like lizards and frogs. Their diet is usually determined by their size, hunting techniques, and environment.
Not all spiders have the same taste. For instance, the jumping spider, known for its incredible eyesight and agility, prefers to hunt down its prey rather than catch it in a web.
On the other hand, orb-weaver spiders build intricate webs to trap flying insects like flies and moths.
Spiders use venom to subdue their prey. This venom not only immobilizes the victim but also helps break down its internal tissues into a digestible liquid form. Again, different spiders have varying venom potency, with some being harmless to humans and others potentially dangerous.
However, for their prey, spider venom is an efficient and deadly weapon.
It’s not just insects that spiders eat; they sometimes consume their kind. Cannibalism among spiders is relatively common, especially during mating. Female spiders are notorious for eating their male counterparts post-mating.
The Benefits of Spiders in Pest Control
Although few of us want to have spiders lingering around our homes, the reality is that they play an incredibly important role when it comes to pest control.
In fact, you couldn’t ask for a better ally when it comes to pest control – spiders are the real MVP. Because they eat so many different types of pests, they can help reduce the number of pests that could potentially carry diseases or cause damage to your home.
And it’s not just the home where spiders shine – they’re also quite helpful in the garden. They happily feed on aphids, caterpillars, and other insects that are known to damage foliage and flowers.
How to Encourage Spiders in Your Home and Garden
While the idea of having spiders around might not be appealing to everyone, there are ways to encourage their presence in a controlled and beneficial manner.
Provide Shelter
Spiders need places to build their webs and hide from predators. In your garden, leave some leaf litter, rocks, and logs for them to take shelter. Indoors, avoid excessive cleaning in less-used areas like basements and attics, where spiders can find undisturbed spaces to live.
Limit Pesticide Use
Excessive use of chemical pesticides can harm spider populations. If you need to use pesticides, opt for targeted applications and avoid broad-spectrum insecticides that can kill beneficial predators like spiders.
Encourage Insect Diversity
A diverse insect population in your garden will attract more spiders. Plant a variety of flowers and shrubs to create a habitat that supports different insect species. This will provide a steady food source for spiders and help maintain a balanced ecosystem.
Spiders As Household Pests
While spiders help control household pests, they can sometimes become pests themselves. Try to strike a balance between appreciating their benefits and managing their presence in your home.
Some spider species are more likely to be found indoors. Common house spiders include the cellar spider, the common house spider, and the brown recluse.
Taking the time to understand their habits and ideal habitats may not sound like fun, but will allow you to differentiate between dangerous versus harmless spiders. That way, you can keep yourself safe while also allowing spiders to go about all of their pest-reducing business.
If you find a spider in your home and prefer not to have it around, there are safe ways to remove it without killing it. Use a glass and a piece of paper to trap the spider and release it outside. This humane method allows you to coexist with spiders without causing harm.
How to Prevent Spider Infestations
To prevent spider infestations, seal cracks and gaps in your home’s exterior, keep your living spaces clean and clutter-free, and regularly check for webs in corners and other hiding spots.
Ultimately, spiders are fascinating creatures that play a vital role in natural pest control. Understanding what they eat and how they contribute to maintaining a balanced ecosystem can help you appreciate their presence in your home and garden.
By encouraging spiders and practicing safe removal techniques, you can enjoy the benefits of natural pest control while minimizing the need for chemical pesticides.
