Characteristics Of Common Spiders

There are a few things you should know about spiders right from the start. Knowing these facts will help you with spider prevention and prevent spiders from outsmarting you as you set your sights on spider management in and around your home.

  • Spiders are motivated by food. They want to live where food is found. What spiders eat mostly is insects. Certain spiders prefer the insects that fly, and others prefer the ones that crawl. If you see a spider or spider web, you can bet that there is food nearby. Remove the food source, and guess what will happen? The spiders will go away.
  • Spiders explore holes. If your exterior has an entry point, you can expect a spider to take a peek inside. If they find a pathway to your indoor spaces, they'll get into your home. Spiders don't make their own holes. That means careful pest-proofing can keep them out. It is also possible to seal your interior so that spiders aren't able to come out of your walls to annoy you.
  • Spiders are drawn to moisture. They need water for survival, and they know that their food source needs water as well. When they find damp conditions, certain spiders will create a web and wait for prey. Reducing moisture can deter spider activity.
  • Spiders that make webs often create egg sacs in their webs. Some spiders have more than 300 eggs inside their egg sacs. That is a lot of spiders waiting to hatch. When they do, your spider problems are going to get worse. It is smart to remove webs and crush egg sacs before the eggs hatch. Doing so will help control spider populations.
  • Spiders prefer to make their webs in undisturbed areas. If you wipe down a surface and remove clutter, spiders may decide to make their webs elsewhere. Maybe today is the day to get out in your garage and get things squeaky clean.

Do you see how these characteristics can help you with your spider control? Great! Now, let's look at why it is best not to have spiders crawling around in your home.

Spiders In The Home Can Be Problematic

Most of the time, spiders are a nuisance. In fact, several of the spiders that live inside Denver homes are harmless. They're not even able to bite you. Many of the spiders that do bite you in your home do so without hurting you enough for you to notice. That is why you find a swollen red bump but don't remember when you were bitten. But we have a couple of spiders that can cause a bite that feels like a pinprick or a bee sting. While these seem like the worst, they're actually not. Even an irritating bite like this isn't a cause for concern. The spiders that present a medical concern in Denver are black widow spiders. A bite from a black widow is not only painful but may also come with symptoms that require immediate medical attention. Fortunately, bites from these spiders are quite rare. 

In most cases, spiders are harmless. Even if they bite you, you won't feel it, and you're only going to get an itchy red welt. But harmless spiders aren't something you can ignore. They make unsightly webs, race up your walls, run across your floors, and appear in unexpected places. If you'd prefer not to step out of the shower and almost step on a spider, we have some prevention tips to help you keep all Denver spiders out of your home.

Five Naturally Effective Spider Prevention Tips

You're almost a spider expert. You know some of what motivates spiders, why they get inside, what attracts them, how their eggs increase infestations, how to deter them from making webs, and what sort of things they do in your home. Let's build off what we've discussed and look at five naturally effective spider prevention methods.

  1. Remove Exterior Webs: Use a spider web removal tool to pick up the spider webs around your home, in your garage, and inside interior spaces. If you see any spider egg sacs, crush them or burn them to destroy the spiders inside. After removing webs, wipe or wash down surfaces to deter future webs. 
  2. Patch Holes And Fill In Structural Cavities: Use a caulking gun and a few cans of expanding foam to block spiders from entering. Fill gaps in the siding or foundation, around door and window frames, around pipes and wire conduits, and inside structural holes.
  3. Weather-Proof Your Home: Make sure your exterior doors are properly sealed. The same materials that keep the cold weather out keep pests out as well. Do away with weatherstripping that isn't getting the job done. Replace door sweeps that don't have a proper seal. If you can see light leaking out of your exterior doors at night, spiders can get inside.  
  4. Reduce Outdoor Bugs: Insects are attracted to light. Keep lights off at night, or consider altering light conditions. Insects aren't able to see light in the yellow spectrum. Swap white lights for yellow. Or install motion-detecting lights. Bugs are often attracted to moisture. Repairing damaged areas of your gutters and cleaning out debris clogs can keep your perimeter from getting damp. Trimming vegetation near your home can also have a big impact. Remove leaves, sticks, weeds, and unwanted grass as well. 
  5. Reduce Indoor Pests: Spiders eat nearly every crawling or flying pest that will get into your home. One of the best ways to keep pests out of your home is to keep things clean. Unsanitary conditions attract pests from a distance. They can smell food items and juice spills when they start to decay. They'll also smell packaged foods that are past due. Be sure to check your food and throw out old items. Keep fresh foods in mind as well. Some pests like fresh food, and they'll eat anything. They'll nibble on food stuck to dirty dishes, pet food, uncovered food left on the counter, etc. As you work to remove food options, remember that your trash is a primary source of food for pests. Keep your trash covered and remove it before pest-attracting smells are created.
