As the weather starts to cool down in Colorado, black widow spiders become more active as they search for warmer spots. From Wellington to Colorado Springs, you might notice these spiders moving indoors, trying to escape the cold. Let’s dive into how you can protect your loved ones from black widow spiders during the fall and winter months. Understanding their behavior and taking a few simple steps can go a long way in reducing encounters.

The black widow spider is notorious in Colorado for its shiny black body and the red hourglass marking on the underside of its abdomen. These spiders prefer to hide in dark, undisturbed places where they can stay safe and warm. As temperatures drop, black widow spiders are more likely to venture inside homes, garages, and sheds. They’re not doing this to scare you; they’re just looking for a warm, safe place to stay during the colder months.

Why Do They Come Inside? Well, think about it from the spider’s perspective. Outdoor temperatures can get quite chilly in Colorado, so black widow spiders seek out basements, garages, and other sheltered areas where it’s warmer. They’re just trying to survive, not cause trouble. But this means you might find them in places where you store things you don’t use often, like holiday decorations or old boxes.

Less Active but Still a Risk: While these spiders aren’t as active in cooler weather, they can still pose a risk if disturbed. They often hide in corners or behind objects, so it’s important to be cautious when moving things around.

To keep black widow spiders out of your home, there are a few easy things you can do. These tips work no matter where you live in Colorado.

1. Regular Cleaning and Inspections

One of the best ways to keep spiders at bay is to regularly clean and inspect areas of your home that are dark and less frequently used. This includes places like basements, garages, and storage areas. Vacuuming and dusting these spaces can make them less inviting to black widow spiders.

Quick Tip: When cleaning or moving items, use a flashlight to check dark corners and behind large objects. This simple step can help you spot spiders before you accidentally disturb them.

2. Seal Up Entry Points

Another effective strategy is to seal up any cracks or gaps around your home. Check around windows, doors, and the foundation for any openings that spiders might use to get inside. A little caulk or weather stripping can go a long way in keeping them out.

Don’t Forget the Vents: Make sure to cover vents, screens, and chimneys with fine mesh to keep spiders and other critters out. This creates a barrier that makes it tougher for black widows to sneak into your home.

3. Smart Storage Practices

If you have items stored away, like in a garage or basement, consider using plastic bins with tight-fitting lids instead of cardboard boxes. Spiders can easily crawl into cardboard, but they have a much harder time getting into sealed plastic bins. Keeping these bins off the ground and away from walls can also help.

For those with pets, regularly inspect and shake out pet bedding or outdoor cushions before use. These items can provide a cozy hiding spot for spiders looking for warmth.

4. Maintain Your Outdoor Space

Keeping your yard tidy is another great way to prevent black widow spiders from making themselves at home. Regularly mow the lawn, trim bushes, and remove piles of leaves or wood that could serve as shelter.

When you handle firewood or other outdoor items, always wear gloves. This simple precaution can protect you from accidentally touching a spider.

If you come across a black widow spider in your home, stay calm. Here’s what to do:

1. Stay Calm: Black widows aren’t out to get you. They generally only bite if they feel threatened. Slowly back away and avoid sudden movements.
2. Safely Remove the Spider: If you’re comfortable, you can use a glass jar and a piece of paper to gently capture the spider and release it far from your home. If that sounds too scary, consider using a home remedy like a vinegar solution to deter them.
3. Call a Pro at OBEX: If you’re seeing a lot of spiders or just don’t want to handle it yourself, professional pest control services, like OBEX, can help. We have the tools and expertise to safely manage spider populations – even if you just get the “ew” factor from them.

To keep your family and pets safe from black widow spiders, it’s important to teach them a few basic precautions:

• Know What They Look Like: Make sure everyone knows how to identify a black widow spider so they can avoid them.
• First Aid for Bites: Teach your family what to do if someone gets bitten, including applying ice to reduce swelling and seeking medical attention if necessary.
• Consider Home Remedies: While it’s always best to consult a professional for medical advice, some people use homeopathic remedies for spider bites, like activated charcoal for venom absorption.
