Pros: effective, inexpensive alternative to sprays, baits
I've seen advertisements for plug-in pest repellents for years and I always put them in a category with other infomercial gadgets--the kind you might buy on a whim and then never use. After all, how could some little thing smaller than a pack of cigarettes stop do the things they claimed? I had endured an army of ants each summer for years. These ants paid no attention to sprays, powders and all manner of pest control. I'd even tried some weird methods of getting rid of them that I read in a magazine--like sprinkling corn meal where they come inside. When the ants eat the cornmeal they were supposed to literally explode. Well, my ants ate the cornmeal and came back for more. I guess I didn't buy the right brand? Anyway, when the ants invaded our kitchen yet again this summer I figured this electrical gadget might be worth a try--not to mention the fact that I wouldn't have to sweep after using it.
I looked at our local Lowe's Hardware and was amazed at all the different ways to kill - or try to kill - pests and settled on the Black and Decker Electronic Pest Repeller EXP420-2P. Since our kitchen is just average size, I chose the model for medium rooms. Other models are designed for larger and smaller spaces.
The repeller comes with two single units per pack. This particular model has a built-in night light and an electrical outlet built into each unit. This way, there's still an available outlet when the unit is plugged in that may be used for any 110VAC appliance. There's also a switch to turn the night light on or off built into the units.
The packaging says that mice, cockroaches, spiders and other pests are repelled by this product and I assumed by "other pests" that the manufacturers surely meant ants too. Operation is painless. Simply remove from the package and plug into the nearest outlet. The only warnings are that the units should not be plugged in near any flammable liquids or into any extension cord. Of course, immersion in water is a no-no. No maintenance is required and cleaning is a snap with just a dry cloth.
How did it work? After installing two in our kitchen, ants are a thing of the past. Just to check, I took the units out to see if the ants were really gone. After less than 24 hours, the pests had returned. There was a warning on the package that some pests might adjust to the ultrasonic waves and still return. The only time our ants returned was when the units were unplugged.
Even though I know these things work, the skeptic in me finds it hard to believe that something this simple--and inexpensive--solved our pest problem. What makes it work? Ultrasonic waves disrupt the pests internal system and cause them to leave the infested area. The sound waves are emitted in random bursts that change their feeding patterns and nesting behavior. So, I guess it gets them so agitated that they seek more comfortable surroundings. The waves are not supposed to effect humans and are harmless to non-rodent pets such as dogs, cats, bird and fish.
I highly recommend the Black and Decker Electronic Pest Repeller for getting rid of unwanted pests. They are a great and effective alternative to smelly sprays and expensive pest control baits. With two units costing only $12.79, they are certainly worth a try.
