Yes!! I tested this theory and it is true. Drains are superhighway for bugs
. Centipedes do drown in water but most drains have no water in them most o
f the time especially at night. After each use close the drain of each sink
and centipedes, spiders and roaches will be eradicated. Why? They will be
under the stopper and when you turn on the water they drown. You will be bu
g free without dangerous chemical but you must be diligent about keeping ev
ery drain closed when not using them.
This also prevents sewer gasses from entering the house while you sleep. La
st thing before bed time, close all drains, open windows for a few minutes
to air out the room and ten sleep like a baby!!
