Death in (or near) the bedroom

Some months ago, before leaving on a holiday, I bought one of those automated insect spray machines (like this example, although the brand is different) that squirt a bit of spray in the air every so often. (You can vary the timing: I set it for about every 30 minutes.)

This is supposed to kill all hapless insects within a considerable range of the machine. I bought it for the walk-in robe that separates the bedroom and the ensuite toilet. Silverfish like it in there, and they were the main target.

One problem I have found with the device is that it makes a bit of a whirring sound every time it goes off. It seems to know when to do it to maximise surprise, such as the other night as I was passing through the robe to make a mid-morning visit to the toilet. I know I can turn the thing off at night, but never think to. Besides, insects are active at night.

The other thing is, given the small amount of stuff it squirts out, I have been very sceptical that it can possibly be effective, unless the bug happens to be within a very small radius of the device. In fact, I was going to do a post about my suspicions that, as a class of product, they might be a great con job. Had any consumer organisation actually tested their effectiveness? (I still haven't looked up that point.)

But then this morning, I found a large, dead cockroach in the ensuite. I assume the spray was the cause of death.

This is enough to make me keep using it, although I still feel I am being unscientific, and it continues to enjoy making me jump at quiet times when I am near it.

That's all I wanted to say.*
