I would like to thank all the Chiang Mai Mail readers who
contacted me and thank you all for emailing in all your mosquito questions.
Please do not hesitate to email me, I will reply as fast I can.
In regards to pet rats and hamsters, yes are a blood
source for female mosquitoes as well so a mosquito net over the cage at
night or in the day will protect them just fine. There is no need to spray
them with mosquito repellent.
