I bought this powder laxman rekha to keep away rat and lozard from my house. but seriously rat and lizard are less harmful than this. I can feel that poisen in the air and that was really bad thing.
may be its working well to keep away rats and lizard but still I think it's not a good product to use. because its placed in the floor and or on wall to draw a line, our small kids always arounding, so they might taste this thing and buy trouble for all.
and also it causes air poisen so please be safe to using this.dont fall for result, better put some cages to cath mouse and throw them in jungle.
after using I didn't found that product is easy to use, you have to keep in mind many things before you placing them in any place.
I would ever say please avoid any kinda of medicine to kill rats, trust me those chemical products are more harmful
