We get Giant House Spiders in the PNW— that’s actually the name— and they can grow to be about 4” across. In addition to that nightmare scenario, every few years a mouse or a rat will die under my house, far enough under that we can’t get it. As if the stink wasn’t disgusting enough, the flies… the flies are awful. A neighbor told me he had these and that they work. What the hell, I’ll try anything to keep the spiders out and the rodents away. So I put these up, I bought 2 sets to cover the whole basement. The first thing I noticed was that I was seeing dead monster spiders. More than I ever had. This was after a few months. Then, we got a whiff of something dead under the house again. Not as bad as last time (Thank goodness) but still, something dead under the house. Up went the deodorizer bamboo charcoal bags (which work insanely well, but that’s another review). I braced myself for the flies. Sure enough, we started seeing a few in the basement, and then a lot. We got No Pest Strips for the windows and still had these all over. Our basement has a separate back storage room, and there’s direct access to underneath the house behind a door in that room. The device back there was on the audible chirp, as is the one located near the entry door. Those are the only pest control in that room. The fly corpse count back there was significant, as it was in the back near the entrance. They absolutely work. I still see some live monster spiders, but not nearly as many as I used to, and definitely more dead ones. We have a lot of outlets down there so I was able to really cover my basement. These things work.

This product works extremely well. It is kept most bugs rodents out of the house. I don’t know what else more to say. That was the reason why I bought it was to keep the interior of my home queen from pest with less spray extermination.

I am shocked at how well these work. We had been paying a pest control service for over a year and were still getting mice, but this actually worked SO much better. The only downside is that at the "high" setting with sound it drives most of my family nuts except for me, who can't hear it. So, we put it on the high setting only when no one is home. The other downside is that if there is a power failure they each need to be turned on manually again once the power comes back on. So, if we are away for a week and there is a short blip in the power, they will be off until we get home again.

We still get mice in our basement but maybe it's less because of these. We also have them in the garage and we do not get mice there.

I got this product because the house my boyfriend and I rent had cockroaches in the kitchen since moving in. I always look for non-killing solutions to a bug problem. I think this product is marketed more for rodents, but we didn't have that issue so I don't know if it helps with that. However, I plugged all 6 of these in different rooms, had them constantly going on the low setting, and turned on the high setting when we were out of the house. This made no impact on the roaches, unfortunately. We gave it about a month to see. If anything, I think the roaches just stayed away from the plugin itself, but they definitely stayed in the kitchen. Giving this 3 stars because it functions as advertised, and maybe it IS effective for larger critters, but didn't help our bug problem.

I have changed my review. I first thought the devices weren't working. But then I read through some other reviews and realized that I had only been using the basic setting, while pressing the button twice would put it on higher frequency. I agree with some of the reviews that state it is noisy and distracting. But what I did is alternate one room at a time on a schedule with my life that means I don't have to be in the room while it is killing the bugs with sounds lol. Now that I have my alternating schedule, fleas seem to be pretty much eliminated!

We have such an issue with squirrels getting into our attic and I think other rodents in the walls. These have really helped them go away and be much less active on the main silent setting. When I hear them and it seems like it isn’t working, I just hit the button and the sound makes the rodents go nuts and leave! I just cannot leave the loud noise on all the time as it is high pitched and irritating. Easy to use and can be used by anyone. It definitely worked within a week.

It makes way too much noise. I feel like it keeps bugs at bay but does not get rid of them.

Good

Realmente su que de principio tenía mis dudas de la efectividad de estos aparatos al final de cuentas he venido comprobando su efectividad pues prácticamente se han eliminado plagas como ratones y cucarachas aunque no es efectivo con los moscos me ha convencido su eficacia al grado que he adquirido un segundo set

No sirve el producto. Los bichos hasta pareciera que se burlan del aparato. NO LO RECOMIENDO

Llego antes de lo esperado. No sé su efectividad todavía. Lamento que no sirva para exteriores ya que pensaba conectarlo en el jardín. Sin embargo trataré de conectarlo en el porche y veremos los resultados. Otro inconveniente es que debe ser conectado a un enchufe que esté a 80cm-1.20 metros del piso. Normalmente los enchufes no están a esa altura

En el modo agresivo son muy ruidosos y molesta a algunas personas. Los aparatos son eficientes, vivo junto al campo y note una disminución drástica en los primeros 4 días, el manual dice que trabajan progresivamente y se tiene que esperar hasta más de 1 mes.
