How does PESTBLOCKED work?
+
PESTBLOCKED emits continuously changing ultrasonic frequencies between 22–65 kHz. The changing sound creates an environment pests don't want to stay in, while remaining inaudible to people.
How long does it take to work?
+
Every situation is different, but you may begin noticing fewer pest sightings within the first few weeks. For best results, keep the unit plugged in and running continuously.
How many units do I need?
+
One PESTBLOCKED unit covers up to 300 sq. ft. For larger homes or spaces with multiple rooms, we recommend using additional units for broader coverage.
Is PESTBLOCKED safe for pets and children?
+
Yes. PESTBLOCKED uses ultrasonic sound that people, dogs, and cats can't hear. There are no chemicals, poisons, or sprays involved.
What pests does PESTBLOCKED work on?
+
PESTBLOCKED is designed to help repel 14+ common household pests, including bed bugs, cockroaches, mice, rats, spiders, ants, fleas, mosquitoes, silverfish, crickets, wasps, hornets, earwigs, squirrels, and bees.
Why pests can't adapt to PestBlocked
Most ultrasonic devices play the same tone over and over, so within 14 days, pests just... ignore them.
PESTBLOCKED is different. It cycles between 22–65 kHz continuously, so pests can never adapt. Same tech commercial pest control facilities use.
That's what makes PESTBLOCKED different from traditional pest control. No chemicals. No poisons. No traps. Instead of spraying stuff that's bad for you to kill stuff that's bad for you, PESTBLOCKED uses ultrasonic sound that pests hate, but you literally cannot hear.

Variable cycling prevents biological adaptation.
✓ Lab-tested for efficacy.
Independently verified on 14+ common pests.
✓ Industrial-grade build.
FCC certified · designed for 4–5 years continuous operation.

We had bed bugs in our bedroom and I was honestly losing my mind. I was washing everything constantly and checking the bed every night before going to sleep. I tried a couple sprays but didn't want to keep using them. After a few weeks, we weren't seeing them anymore. Being able to sleep without worrying about them has been such a relief.

I started noticing roaches in the kitchen and it got bad enough that I'd turn the lights on at night and check the counters. I tried sprays and traps, but they just kept showing up. After a couple weeks, I wasn't seeing them nearly as much. Honestly, I wish I'd dealt with this sooner.

The fleas were driving me crazy. We were vacuuming all the time and treating the house, but I'd still find them around. I was getting tired of putting more chemicals down, especially with pets around. After a few weeks, we noticed a big difference. It's nice not having to constantly worry about fleas anymore.

Frequently Asked Questions
Find answers to common questions about our products, returns, and more.
Where should I plug in PESTBLOCKED?
+
For the best coverage, plug the unit into an open wall outlet in the room where you notice pest activity. Avoid placing furniture directly in front of the unit, since clear space allows the ultrasonic waves to spread more effectively.

+
No. Simply plug PESTBLOCKED into a standard outlet and leave it running continuously. There are no batteries, chemical refills, traps, or sprays to replace.
Can I leave it plugged in 24/7?
+
Yes — and that's exactly how it's designed to be used. PESTBLOCKED runs 24/7 on extremely low wattage, using only a tiny amount of electricity while continuously protecting your space. Plug it in once and let it work in the background.
Does PESTBLOCKED work for bed bugs, fleas, and cockroaches?
+
PESTBLOCKED is designed to help repel a wide range of common household pests, including bed bugs, fleas, cockroaches, mice, rats, spiders, ants, mosquitoes, silverfish, crickets, wasps, hornets, earwigs, squirrels, and bees.
