If you have security cameras outside your home, you might be wondering why spiders love to spin cobwebs across camera lenses.

The truth is, spiders don’t actually love your cameras—they love the bugs attracted to the infrared light emitting from your camera. This can be a real issue for homeowners because spider webs not only obstruct visibility, but can also trigger false alerts for motion-activated security cameras.

If you’ve partnered with a quality security vendor with professional monitoring, your security team may either alert you to the blockage or send a representative out to clean up the webs.

However, if you’ve self-installed your security system, it’s important to regularly check your setup and perform maintenance as needed.

So, what can you do to prevent spider webs, insects and other bugs from affecting your outdoor security cameras? Read on for tips from our security experts.

Keep Your Security Cameras Bug-Free

There are a variety of ways you can keep spider webs, insects and other bugs off your home security cameras. Here are a few ideas:

  1. Apply lubricants to the outside case of your camera. Cover the body and surrounding area of your camera with a lubricant like Teflon spray, silicon or Vaseline. This will make the camera too slippery for spiders to spin webs on it. Just be sure to cover the lens with a paper towel before applying a thin layer of lubricant.
  2. Attach a dryer sheet to the camera. Use a rubber band to attach a dryer sheet to the outside of your camera. The strong smell will keep bugs away.
  3. Disable the LED lights. Bugs are attracted to the LED lighting around your camera lens. If your camera allows, turn it off.
  4. Loop a flea collar around your camera. Flea collars have been known to keep spiders and other bugs away. Consider attaching one around your camera.
  5. Spray bug repellent around cameras. To keep bugs away from your outdoor surveillance camera, use bug spray or insecticide around the protective housing of the camera. Use this guide for help selecting the right repellent.
  6. Sweep camera areas weekly. Regularly clean the camera’s exterior, housing, enclosures, cover and shield with a soft-bristled brush to remove existing bugs and webs.
  7. Use a fan to prevent spider webs. Consider investing in a low-price computer fan to keep spiders and other bugs at a distance. A fan will prevent spiders from building webs around your lenses and will also keep bugs away.

The tips above aren’t automatic solutions. You may have to repeat them a few times to see results. But, don’t overdo it. Be mindful of pets and young children when spraying pesticides, and ensure your cameras have protective housing before applying chemicals and lubricants.

Configure Your Camera Sensors Appropriately

In addition to keeping bugs off your cameras, it’s also recommended that you adjust the camera’s motion detection alert settings. Simply adjusting the threshold of activity that triggers alarms can prevent false detection alerts. This way, you won’t get notified every time a spider or other insect is crawling on your device.

If available, enable your camera’s intrusion mode or configure the settings to only send notifications when something of a certain size is in view for a certain period of time.

Whether you maintain your home surveillance system or it's monitored around the clock by a professional security team, it's important to have your cameras professionally installed for the best lifetime performance. Contact a trusted security expert today to get started.
