Frogs, Mosquitoes, and other wildlife

Lately, I have had trouble sleeping. Around 1 a.m. about 40 frogs outside my window will start ribbiting or making that sort of sound. Its not a constant noise either, it goes in waves, like a crescendo of music, following a random pattern. They get scared when a scooter or car comes by, and the air is filled with an eerie silence. Than one of them performs an introductory ribbit to test for danger. Thereafter the initial ribbit, the others will join in, I wonder if its mating season or something, but its really annoying. The fact that its not a constant noise, but something constantly changing can be quite frustrating. It kinda sounds like hands clapping, so every 30s, when they pause, I pretend I am making a speech, to which they will subsequently be clapping at, like supporters at a political rally.

The mosquitoes are getting very smart now. I can no longer find them in the room to kill, they have found some excellent hiding places, perhaps behind the closet or bookshelves. They come at night when I sleep, before they used to come as soon as I turned off the lights. Obviously I would hear them coming and quickly turn on the lights and smite them down with Zeus' fury (and my trusty mosquito zapper). Now they have become smarter, they wait 15-20mins until the lights close (persumably till I fall asleep). I was fooled once, but hence forth I stayed awake waiting for them (easier since the frogs keep me up, perhaps trying to warn me?) and swat them away when I hear them coming. Unfortunately, now they have become too smart. Recently, I waited an hour and went to bed at 1:30 a.m. I was woken up 3 hours later at 4:30 a.m. by the buzzing of a lone mosquito bent on a late night snack. He had bitten my hand already before I had the chance to come out of my deep slumber. I quickly flicked on the lights and terminated him with my zapper. Pissed I stayed up another 30 mins (till 5:15 a.m.) waiting to see if any more were left in the room. The room was clear and I resumed my sleep. Unfortunately, I cannot keep guard the entire night waiting for them to come for our duel. I have decided to give in and get the chemical repellants, as much as I abhor their potential side-effects. Peter suggested one he uses that you plug-in, and it burns this tablet and repels mosquiteos from your room. I have been using it the last 2 days and its been quite good, completely odourless and my room mosquito free. I am not sure if its the tablet or because I have been more vigilant about keeping my doors and windows tightly sealed. My window screen is in good condition, so how these carnivores get into my apartment is a mystery.

I guess an easier solution might be to just take one of the frogs from downstairs and put them in my apartment, but I really dont have time for a pet, and honestly, dont think I have that many bugs that would warrant a reptile, nor enough space for one to be hopping around. I wonder if they could take care of my ant problem as well though? um....than it may just be worth considering...
