Ultrasonic bug deterrents – Dont believe the hype

Filed under: Random — joel.cass @ 10:41 am

According to some, these things work. Last summer we had a nasty cockroach problem. I went to bunnings and got a set of these “sonic guard” ultrasonic insect deterrent devices.

I installed one in the kitchen and one on the opposite side of the house.

Well after a few months we saw no real difference. One day I got out the bug spray and sprayed around the kitchen. I was surprised to see a baby cockroach stumble out of the device so I sprayed the device… And this is what happened:


Mother cockroach must have laid her eggs in this thing – and they hatched!

Not to say no more – the device was binned – don’t let anyone tell you these things work – they are a scam – you’re better off using cockroach baits and glue paper.
