mine is like this ... if i peel off the sticker it look all black like yours

but still no hole to release the smell from the inside

where to buy borax?
coz i saw a tutorial at youtube dough mix with borax then spread around will kill a lot of cockroaches just becareful of pet dogs and cats though....

Borax is sold as the 20 mule team brand of detergent booster at Acehardware stores. It works to soften hard water I think.

Mixing borax with sugar/dough might work well but I think boric acid was the original recipe.

u mean this?

inside it already got the poison. U put it near their nest, and they will come out and eat that bait later... tomorrow u will see them grow very big and able to eat your dogs and cats.. nah just kidding    they will die soon after they eat the bait.

this one not that good. Get the Combat. Its more effective to kill the host.
the rest just kill the cock that were fed, it didn't kill the nest.

where to get combat brand

Just draw border with this. any insect cross border will get executed.

Y'know, the cockroach isn't exactly a pest and is just misunderstood. It isn't as dirty we you think it might be and while their presence actually helps to keep your household clean. Of course, if your house has many roaches than its actually a sign that you keep a very messy house but its not their fault now isn't it?

Not trolling at all. After all, this is serious /k so here's the sos tomato and kicap.

Aku pun benci lipas terbang.tikus aku boleh tahan lagi

this is super effective
i sprayed inside my car
leave it a nite
next morning the cockroach is everywhere
all died upside down
i think almost around 20+

Want to ask how to prevent roaches coming into the house.??
Basically my kitchen, at the back of the house. Behind my house is small lane and I believe where the breeding ground is.

I used the Ridsect bait and no doubt they died like sh*T everywhere. But my problem is,....they keep coming in and die.

How to prevent them from entering at the first place? ?? any suitable roach killer for it?

Thanks

Roaches are Terra Formars...i will kill them or they will kill me...but msia roach is damn scary and uglier than overseas...
