Like most people we also always have had cockroaches as part of our family and have been sharing the space with them.
- Tried Red Hit, Kala Hit, and all sort of sprays, none of them gave any permanent solution.
- Lakshman rekha and many of other chalks.
1st solution spray , will just kill the lazy cockoches whom you could chase and spray on them.
2nd solution will kill all those who cross the chalk line in next 24 hours.
Certainly 2nd approach ,chalks, were better than sprays. but new generation would come back in next 2-3 weeks.
I recently tried following herbal product "Exit No Entry", its some local product manifectured in Bangalore itself.
I bought 5-6 packets of it, its some green color gel type stuff, I made out small-small balls out if it.
balls as small as half inch diameter. (they are as big as keys on my keyboard ) , half size of of normal naphthalene balls.
Planted them all in all my house. 50% of it was in kitchen.
In Kitchen: Below wash basin , in all storage below kitchen platforms and on shelf etc. behind refrigerator.
Since its sticky gel just like M-seal, you can stick it in places where its not visible to kids.
In Living Room : I kept in all corners of TV stand inside and behind shoe rack , in the bottom of sofa.
In Bedroom : in wardrobes/dressing table in bedroom.
In bathrooms. All chhajja storage in home, even in store room.
Result was not immediate like Lakshman rekha, whenever I put Lakshamn rekha, all of them would die in next 24 hours. while in with this herbal solution I kept in cleaning dead cockroaches till on week, after putting this herbal solution, and its been 3 months now i have not seen a single cockroach in house.
Eariler whenever I use to wake up in night and go to kitchen for drinking some water or to eat something,
the moment I put on the light, there use to be cockroaches stampede.
Now I dint find any of them in the middle of night also. Once I kept some eatable on kitchen platform and checked at 1 -2 AM but there was no one to eat the left over.
Bottom line: Any Herbal products like "Exit - No Entry" does work. buy two packet for kitchen and one packet for all other room.
Disclaimer : I am not connected with this product called "No Entry" in any case. Just sharing my experience. I think other herbal products that are available on nearest groceries shop should work as well.
