You don’t have to worry now !!! When you call the Godrej pest control to kill the insects and flies they charge you a hefty amount for annual maintenance. I had called them last year and noted down the name of the killer insecticide they used.  It was damn effective, not a single insect or fly or mosquito for the next 15 days.
I went to a fertilizer shop and bought the insecticide and started spraying my self every 2 weeks, We don’t have a single mosquito or cockroach or fly in our house now.
You don’t have spend on costly mesh, or bear the trouble of smelling sprays like hit.

I am sure you must be eager to know what it is.

here you go .....

What impressed me was it doesn’t smell at all.

Just mix 20 ml into 1 lt of water and you are good to spray 200 sq yards or 1800 sft.
1 lt bottle costs you 750/-.  this is enough for 2 yrs.
you also need to buy a pressure spray, it will cost you 300/-

Please remember.

1. you can spray this in your gardern
2. bathrooms.
3. All corners of bedroom
4. kitchen sink and corners (take out the utensils)
5. on the exterior walls.
6. on the terrace.

What are you waiting for, go buy it,  hurry the monsoon is in and you need to impress your family.
