i use that too.... it takes time more or less 14 days to work.
and depands how much they take in their home.
just try coust u more or less $5. few years ago price

then will Wilson works better than Raid????

other method..

if you find the ant dou

use 洗潔精+水 1:2

倒入ant 竇 入口直到滿寫。。。 that works too

the brand i used normally takes less than a week.. very effective.  not sure why they stopped making it.  then I have never found a good and reliable one yet.  my friends tried some they got from home depot, also mixed reviews: one friend said it worked well, the other said the opposite.

more or less the same

don't know exactly where is the 竇.....

but since there's too many ants around my backyard walkway.....

i destroy two ant 竇 using 洗潔精

i soak the 入口first...

and than i use a power wash, (pencil head)  to make the entrance bigger and dipper

and i pour few pails of the stuff to soak until the water cannot go inside anymore..

that's a good example of how people react to negative comments.  Out of the 14 comments, only 3 were bad.  But you lost confidence already.    You have to understand, unless people 做馬, it is normally harder for customers to write positive comments than negative ones.  When you are not happy with a product, you complained; but when you are happy, you just don't complain because most people are not willing to take an extra step to write positive comments, simply because by doing that won't benefit themselves most of the time.  When you see so many good comments and just a few bad ones, I think the product won't be too bad.

hahahahahhaha......I just want to find a efficiency way to kill them....and I still have few products left over from years ago....could be done them before try new.....

But I was thinking to burn them....

但 D 嚹位我唔知 D 水會唔會逼返入屋嘛....
