Are certain areas of Thailand worst for mosquitoes than others (one island better than another)?
And how do hotels treat for mosquitoes --do they spray the grounds (like in Hawaii)? Are there electric plug in bug zappers, coils, treated nets in the rooms?
We are planning on Peninsula in BKK, Chedi in Phuket and 4 Seasons in Chiang Mai in Feb/March. If anyone has experience with these hotels, that would be helpful.
I was planning on using plenty of deet but just talked to someone who was still bitten a ton with that precaution. I'm allergic to mosquito bites so am trying to find out how bad it is. Thanks.

in bkk and CM you will not have to worry about mosquitos at that time of year....i would only worry about them if i were going to be in jungle areas or in places like cambodia...in 5 trips to thailand we have never used any bug spray or treatment....i do think i remember the pool areas being sprayed sometimes at nite, however...

Never saw a mosquito the entire time in Thailand. Also stayed at the Peninsula and it's not likely a mosquito ever passed the portal there.

As to the Chedi in Phuket or the Four Season in Chiang Mai, also doubt you'll see mosquitos. Of course, if you keep your windows open, especially between dusk and dawn, can't guarantee there won't be mosquitos in the night air (that is mosquito biting time) - though we did sleep with open windows up in Chiang Mai with no problems. And while south in Phuket, most women wore abbreviated clothing because of the heat and no one seemed bothered by mosquitos.

Of course, bring repellent and use it in the evenings (if so inclined) on exposed skin, but don't forget to wash it off before going to bed.

Our only time we might have come in contact with mosquitos could have been during the few days we were in Cambodia (Angkor Wat), but our 5* hotel had no mosquito problem, though when dining outdoors in the evenings we did use repellent as a precaution only.

Didn't see zappers, coils or treated nets our entire time.

I can't remember ever being bothered by mosquitos in Bangkok. I have seen (and been biten) by a few mosquitos at the various beach resorts, and there were lots of mosquitos in the Golden Triangle area of Thailand. Whether you encounter mosquitos will depend on exactly where you are going and the time of the year. Deet is the only repellant that has been proven effective for more than 30 minutes per application. Use a repellant that has 25-35% deet. You can also buy pytherin sprays for your clothes that will repel mosquitos. However, I wouldn't expect major mosquito problems at any of the places you are visiting.

Note that the mosquitos that carry malaria bite at dawn and dusk. None of the places you are visiting are considered risky for malaria. However, the mosquitps that carry dengue (which is an increasing problem inn many tropical places - including Hawaii) bite during the day.

Take repellant, use it as needed.

Just got back and still have bite marks! Lots of mosquitos in the south, but really only problematic at dawn and dusk. Some places do "smoke" the grounds.

leslie, where did you go? I've heard some places are worse (koh samui worse than phuket). did you use deet or recommend any other precautions that work (or don't work since you got bitten bad, it sounds!). also, how was the weather?

Mae, we went to Samui, Ao Nang, and Phi Phi Island. I dont' like using Deet, so just avoided being outside during dusk. My daughter gets eaten alive...she must taste good...but deet helps. I saw no coils or zappers in use, and this was a suggestion that I made to the hotels that we stayed at.

I dont' think there was much of a difference in locations in terms of mosquitos.

Weather-wise...we arrived in Samui on Dec 19...it rained for two days and then was gorgeous until we left on jan 7. My family, who lives there said that normally the rainy season is over by early December but it went a little longer this year.
