Review of Pest Offense Electronic Pest Repeller

The Original Electronic Pest Repeller

Pest Offense products are one of the more well-known electronic pest repellers in the market. And it’s not surprising because their electronic products are among the best in the industry. But of course, like every manufacturer, there are a few things here and there that need to be improved.

The Pest Offense Electronic Pest Repeller claims to get rid of mice, roaches, and other pests including spiders (which I fear the most). Well, according to over a hundred positive reviews, several comments, and our own experience, it does its job effectively and safely. How? This device alters the electromagnetic field in your home’s wirings by sending random impulses. This drives pests crazy and renders them unable to live in your home. So basically, it drives pests away by attacking their nervous system. If you wish to find out more about this nifty gadget, click here to view more pricings, ratings, and reviews.

Just one unit of this product is good for one level of an average-sized home. You might need to purchase a few more units if your house is bigger than the average.

A Few Ups and Downs

Pest Offense Electronic Pest Repeller

The Pest Offense Electronic Pest Repeller gets mixed reviews in Amazon. Personally, I think it’s because of poor installation techniques and because each house is wired differently. It IS a plug-and-play device but you need to know where to plug this product for maximum effectiveness. As one satisfied customer suggests, you have to determine how many circuits your house has and install one unit for each circuit. Read here for the full tip.

Like all ultrasonic pest repellers, this gadget is a safe and humane way to get rid of pests – it doesn’t contain any hazardous chemicals so you don’t need to  worry about your children or pets getting into accidents because of chemical-based repellers or traps. And speaking of safety, I’m sure you’ll like this one – this model is EPA registered! It means that  this  model is registered to the Environmental Protection Agency or EPA and has passed a rigorous screening process, ensuring that this electronic pest repeller is safe to use in your home.

This is not for you if…

This product is not recommended if you have small pets in your home such as hamsters, guinea pigs, gerbils, and tarantulas as these animals can detect the electromagnetic impulses that the repeller releases and will drive them crazy. If you have rodents as pets it is recommended to choose another pest repeller. I recommend using Victor M2524 Electronic Mouse Trap if you have a mice infestation or TERRO PreFilled Liquid Ant Killer II Baits 6 Pack T300 if you have an ant problems. The last one is a chemical based repeller though, so be careful.

Is it Effective?

When it comes to the products effectiveness, we’ve got nothing to say but wow – this bad boy works superbly under the right circumstances. What I’m talking about is that your home should have sufficient wirings so Pest Offense can maximize its potential. It doesn’t work overnight too. It takes about a week or two before you see the effects of this nifty device. Hey, you didn’t get an infestation overnight!

What’s more, according to some reviews the repeller doesn’t affect roaches as much as it affects other pests. It worked on them when we’ve tested this bad boy but I’ve read in various comments and reviews that the product doesn’t have much effect on roaches. I’m not too sure if they just plugged it in on the wrong circuit or their unit is broken. If you have a roach infestation, don’t try your luck with this product. I recommend using another one like Riddex Sonic Plus Pest Repellers which are very effective against cockroaches.

Begone Mice and Spiders!

The Pest Offense Electronic Pest Repeller is most effective against spiders and mice. So if you have any of the infestations mentioned, this product is a great buy. According to reviews however, the unit has minimal effect on ants and roaches so if you have these pests lurking in your homes you may want to look at our ultrasonic pest repeller chart.
