Using a Mosquito Trap Inside?

We live in Jakarta and are currently in the dry season where the mosquitoes are at their worst. I was just looking at the drink bottle mosquito trap.

We have two young children and have nets over their beds and keep the top of the house closed and ACs on. As you can imagine however the top of the house leads outside and obviously the mosquitoes can still get in. We spray an hour before bedtime however we are finding a few are still getting in or managing to avoid the spray or we believe they maybe getting in through the exhaust fan shoots.

Anyway my question is, the top floor of our house is quite large, would it be worthwhile placing a couple of these traps around say perhaps in our walk-in robe, which gets very little natural light and perhaps on the top of a cupboard in another room? Or do you think we will attract more and perhaps defeat the purpose of the trap?

Your advice would be greatly appreciated. Thanks.
