It's fall, and that means a rush of unwanted insects start to make their way into your home. Or in the case of spiders, they crawl out of whatever crevice they were hiding in.
Late summer to the end of October is prime time for spiders, which is why you're seeing more of them
. This time of year, males come out of hiding in search of females, and the spiders themselves come out in search of food, aka, other pests."Spiders are just following their food," says Jeff Schumacher, owner of All-Safe Pest & Termite in Texas. "Gaps in windows, doors, and your foundation make it easy for spiders and other insects to come inside, seeking shelter from the changing weather outside."
But how do you keep them out? Using new ultrasonic wave technology to make
their environment uncomfortable. That's how.
Ultrasonic Indoor Pest Repeller uses nontoxic ultrasonic waves to deter pests
How does ultrasonic spider repellent work?
Instead of using harmful chemicals and pesticides, an ultrasonic pest repeller uses multi-frequency ultrasonic waves create an uncomfortable environment for common indoor pests. This particular one works within a frequency range of 10kHz to 65kHz, which sits right between audible hearing and a range us humans cannot detect. Human hearing typically caps out at 20kHz, so unless you have this device on its highest pitch setting, you won't be able to hear it.
For reference:
- 10 kHz to 20 kHz is the audible range. This is the highest pitch for ultrasonic waves. Adults lose the ability to hear frequencies above 12kHz to 15 kHz, but most children and young adults can easily hear up to 20 kHz. It sounds like a sharp, piercing hiss or whistle.
- 20 kHz to 65 kHz is true ultrasonic. These pitches are completely silent to the majority of humans. However, many animals and pests can hear it, which is why it can be used to deter pests like mice.
Do ultrasonic waves actually repel spiders?
It can, some evidence has shown that spiders retreat from ultrasonic waves. While research is limited and ongoing, the initial signs show some promise that this type of technology can repel spiders without the use of harsh chemicals. Pest control companies has a whole will say they don't work, but that is mainly in the discussion of rodents, as these mammals can get used to the sound instead of avoiding the home entirely.

Are ultrasonic waves safe for pets and kids?
