3 Things You Didn’t Know About Household Spiders

Written by Aptive Pest Control July 30, 2024

Most of us have had an unexpected encounter with a spider at home. Household spiders can evoke a mix of fear and fascination. While many people think spiders are just creepy crawlies to be squashed, there’s much more to these eight-legged creatures than meets the eye. Today, we’re debunking spider myths and revealing some surprising facts about these houseguests.

1. Household Spiders Are Expert Pest Controllers

Keeping Other Pests Under Control

Did you know that some household spiders play a role in pest control? These arachnids are nature’s exterminators, feeding on a variety of insects such as flies, mosquitoes, and even other spiders. By doing so, they help keep the population of these pests under control, reducing the need for chemical pest control methods.

Specific Spider Diets

Different spider species have specific diets, which means they target different pests. For instance, the common house spider (Parasteatoda tepidariorum) primarily feeds on flies and ants. Meanwhile, the cellar spider (Pholcus phalangioides) is known for catching and consuming other spiders, including potentially harmful ones. This natural predation makes them beneficial inhabitants in homes, particularly in basements and attics where other pests tend to accumulate.

2. Most Household Spiders Are Harmless to Humans

Debunking Spider Myths

One of the most prevalent spider myths is that all spiders are dangerous. In reality, the majority of household spiders are harmless to humans. Spiders like the common house spider and the daddy longlegs have venom that is either too weak to affect humans or fangs too short to penetrate our skin.

Understanding Spider Venom

Spiders use venom to subdue their prey, but this venom is usually not potent enough to harm humans. The infamous black widow and brown recluse spiders are exceptions, but they are relatively rare and typically avoid human contact. Understanding this helps reduce unnecessary fear and allows us to appreciate the role of spiders in our homes.

3. Spiders Can Be a Sign of an Infestation

Indicators of Other Pest Problems

If you see many spiders around your home, it might suggest an underlying issue with other pests. Addressing these primary pests can help manage spider populations indirectly. For example, a high number of flies or ants might attract more spiders to your home. By targeting and reducing these primary pests, you can create an environment less inviting to spiders.

Signs You Need Pest Control

While some spiders can be beneficial, there are clear signs that professional pest control might be necessary:

  • Multiple spider webs: An abundance of spider webs, especially in frequently cleaned areas, can indicate a larger pest problem.
  • Frequent spider sightings: Seeing spiders regularly, particularly during the daytime, might suggest that your home has an underlying insect infestation.
  • Bites and skin reactions: Although rare, spider bites can happen. If you or your family members experience unexplained bites, it might be time to call in the professionals.
  • Persistent pests: If you continue to see other pests, such as ants, flies, or roaches, despite the presence of spiders, professional pest control can address these issues at the source.

By recognizing these signs, you can take proactive steps to maintain a healthy home environment without the pests.

A New Perspective on Household Spiders

Instead of viewing household spiders as nuisances, consider their role as natural pest controllers. By understanding and appreciating these arachnids, you can manage your home environment more effectively.

However, while spiders may have some definite benefits, not everyone will appreciate their presence in the home. If you need help from professional pests control in removing spiders or other pests from your home, reach out to Aptive, we’d love to talk to you and help out.
