Anyone facing the wrath of mosquitoes ?

Its getting worse with the mosquitoes.

1. I have mosquito bat.

2. All our windows & doors are installed with Mesh.

3. I have mosquito net like as shown in the pic.

we all sleep on the floor under this net, but in the midnight, lot of mosquitoes are getting inside that net. How is that even possible?

I close the doors by 5 PM and open them back by 7 PM only which is the peak time for mosquitoes to enter inside the house.

Cant use Mosquito coils & repellents like good knight, all out because of my COPD mother.

Anyone facing this? How did you fix this?

My issue might look like a silly complaint, but mine and my family's sleep is getting worse because of this.
We cant even sit at peace inside our own house.
