is this effective against cockroach?
Actually - I forgot to mention that the U-bend has to be filled with water to impede to passage of bugs, AND really needs to be filled up regularly as it will either dry out, or the water sucked out by passing Typhoon winds etc.
In the ~20 years plus that we have lived in our own home, I have only slayed two big fat roaches that had the impudence to try to invade under the front & back doors.... and nothing via the floor drains !!
Maybe because its humid. Autumn and almost winter thats why cockroaches is coming out.
Thanks for this - I got some from Wing On. IN the basement section next to the mops, 3m e-cloths and near the car cleaning section.
QQ - the 'round' one for the floor drains seems to just 'sit' on top of the drain and isnt actually stuck on (unlike the wall one) - is that right????!
