In Puerto Vallarta, there are big flying cockroaches as one example of bugs and insects. I have never really had a problem with these cockroaches. Sometimes I will see them in my house, but they will already be turned over on their backs and cannot get up, and then they die. These are not the little cockroaches that come because there is food and grease like I am used to in restaurants in Chicago. These are big ones that may fly in if you leave your door open from the outside. There are, however, very few flying cockroaches. When I leave my door open, these flying cockroaches do not just come in. I do not see them that often. I have never woken up and had one crawling through my hair, for example. I may have had two in my house in the four months since I moved into this new house. I do not know exactly how they get in or what they do, but I always seem to see them when they have already flipped over on their backs and they cannot get up so they die. I have never seen them really crawling around.
Another bug problem is that there geckos all over the walls. My mom is super afraid of them so she said she does not even want to come down to Puerto Vallarta because she looked at the US $500 a night hotels and there are even geckos there. You just can't get rid of them. But the thing is these geckos are really nice and really scared of people. They just stay up on the corners of the walls. I have never been able to catch one or touch one. I personally like them and I do not see anything wrong with having these geckos around. I do not mind having them all around my house. You don't even really see them that often. Sometimes when I turn the light on, I will be able to see one scurry away somewhere.
As far as mosquitoes, the situation with them can get bad. Some of the places here in Puerto Vallarta, including the place where I'm in and is more for Mexicans and not for expats, will have a truck like I am used to in Chicago come by every two or three nights spraying mosquito repellent.
The first house that I lived in with my friend did not have any screens on its windows. If you open the windows, all kinds of mosquitoes would come in. That is not good. What I would have to do then is fall asleep with a fan directed at me so the fan blows the mosquitoes away and they cannot get to me. I have screens in my house now. Even if I leave the door open when I let my dog go out the front, I do not really have too many problems with mosquitoes, but they are definitely down here in Puerto Vallarta.
In Chicago, the problem with mosquitoes, bugs, and insects is pretty bad, too. I would not say the problem is worse in Puerto Vallarta than in Chicago. I would say the problem is the same as in Chicago.
The only thing that you have to worry about down here in Puerto Vallarta is dengue fever, which isn't really that common. It brings out the same scare as when the West Nile virus was big and people were afraid of its spread.
I get bit. I think I have a couple on my leg right now that have been itching. It is not that bad that you get eaten alive if you go out. Obviously in the rainy season, it is a little worse.
To stop the spread of mosquitoes in Puerto Vallarta, the local government instructs residents not to leave any standing water around. If you do have standing water, pour bleach in it because that is where mosquitoes lay their eggs and hatch and the bleach will keep this from happening. The government also reminds people to dump out buckets with water that will not be used so that there is no standing water.
