Does Not Work for Brown Recluse
I waited a few months before writing my review on this product since it is very difficult to evaluate whether it is working. However, I have come to the conclusion that it is not.

We had an infestation of brown recluse spiders. I contacted a spider researcher at KU and brought him a specimen to verify this. I asked him about his opinion on the sonic devices and he said that he really doubted that they worked. Despite his opinion, I thought I would give them a try myself because they have received many positive reviews.

Since I had been capturing brown recluses to show to the spider researcher, I had one in a jar when we bought the sonic devices. Since they are supposed to repel spiders, I expected, if I put the spider in the jar close to the sonic device, the spider would react negatively somehow, such as crawling away from it. However, when I put the jar next to the activated sonic device, the spider did not react at all. It did nothing. I even tilted the jar so that the high-pitched sound would enter the jar. No effect. Despite this, I suspected that maybe the glass of the jar blocked the sound somehow. So I gave it a few more months.

We continued to have spiders in our house. However, there were less than usual. This could have been (and looking back probably was) because we had taken other measures for killing them. I hunted for and killed them every week. We also laid down tape for them to get stuck on, which captured a few. But I thought that the lower numbers might be because of the sonic devices, so I recommended some to my parents who also had brown recluse.

They bought some (though they were a different brand). But today, I just killed a brown recluse within 5 inches of one of my parent's sonic devices. And my girlfriend just reminded me that about a month ago I killed one within about 2 feet of one of *our* sonic devices which are the brand mentioned above. So what this means is that at least some of these devices don't work on brown recluse. And at worse, none of them work.

If you want to sucessfully survive brown recluse, here is how you do it (this advice comes from several spider experts who I have spoken to or read articles from since we first contracted this problem):

- Shake out your clothes and your towels before you use/wear them; most bites occur in unchecked clothing
- Kill every spider you see; as happened in our case, this will likely cause their numbers to dwindle
- If you own your home, seal up cracks that lead outside and to the inner walls
- Lay down duct tape sticky side up or buy the spider traps of the same design

Spiders do not respond to insecticides and in fact insecticides make it easier for brown recluse to find food. This is because the insecticides kill the insects. This makes them trivially easy for the brown recluse to find and devour. Unlike many spiders, brown recluse will eat almost anything, including dead bugs. And even if you eliminate all of the insects completely, brown recluse can go for months without food. Unless you seal your home and fill it with powerful nerve gases that kill any living creature (which has been done), you are wasting your money on insecticides.

Now my family has told me that the sonic devices are effective for mice. And other reviewers have said they work on things like roaches. But they do not work for the brown recluse spiders which plague the mid-west and they may not work on spiders in general.

If you have brown recluse, just be careful and kill them yourself. You will likely lower their numbers.

And don't kill web spiders: they eat brown recluse (which don't make webs). You can tell a brown recluse because unlike almost any spider, they have three eye pairs instead of eight eyes.

My two cents... In depth process for condo and home.
The originals I had did the job and no more mice after a day. Bought this model as my older ones are slowly failing one by one after 5yrs of service. I would only say that when I first starting uses these sonic products, the mice just went to another part of my condo until I plastered it all over the place - one in each room and two in the larger rooms. Total Units: 8 in a 1000sq ft condo.

My parents split level home was another issue though. I ended up buying a bunch of different types and brands and staggered putting them up - in a different room each time to drive them to another location from top to bottom until they left house.

Total cost for the home effort was like $300 worth of these silly little plastic critters; still a far cry from having a fumigation done not to mention making yur home unlivable for a couple weeks too. Gave the remaining ones away to friends in the city... and kept a few for backup. Final: 18 in a split level 4 floor home (4 bedrooms, 3bathrooms, kitchen, living room, dining room, foyer, basement).

I also recommend rotating between a couple brands - I use Sunbeam SUNBEAM SB103 Electronic Pest repeller as an alternate.

My cats hate it!!!
Sorry to say this is not good for pets like it says. My poor two cats as soon as I plugged them in they went running to a room that did not have them and would not come out. Please do not get if you have cats.
