Difficult to say if it works.Still had one or two crawlers.But if they don't like it where are theygoing to go not to the front door for an exit are they

Installed plug and mouse traps on the same day, caught mouse in mouse trap, don't think this does much but may work better for insects than mice.

dunno - not as good as the last one I bought for which I can;t find that make ?

I HATE spiders and in September get an average of half a dozen big ones a night in the house (they’re coming out early this year - seen a few already!) This device has been plugged in the kitchen since last summer and they seem to “freeze still” in the corner outside the house rather than coming in, which for me is amazing! I’ve had very few other bugs around the house also. For me, this product WORKS without harming the critters. Cheap price, well worth a go! 🙂

Not very good to use didn't work in my eyes.

It works! We still have from time to time one lost one flying in other parts of the house but not in designated area. Worth buying.

Have no idea if it's working...

Have not seen anything in my bedroom since putting this on. Thank you , i now sleep soundly ! Amazing , I live near trees and fields so I would get them ever now and then. Best £10.00 I have every spent. I thought I'd buy the cheaper one and then decide if I spend larger money later and I'm glad I did because the cheap one does as it says.......
