we went to farm fleet store bought 2 traps ($4.95) which were yellow
plastic flanges with a dark green hourglass shaped garbage bag hanging
from the yellow plastic-stick a little package of included bait on the
yellow plastic just above where the bags hook on. totally gross they
swarmed the bags so dont hang them in public area but by the end of the
day the bottom of the bags were bulging with thousands of them and the
next day we didnt have any more around. advice on the net is dont do
this unless the entire neighborhood does or you will atrract everyones
to your yard but i think we were the only ones and 2 bags took care of
it. i think they are in colonies rather than evenly spread across the
lands.
