Why do mosquitoes bite some people and totally ignore others, even standing next to one another?
Each person (and other animal) exudes a cocktail of carbon dioxide and other emanations, and we also emit heat. Mosquitoes may discern any of us as human beings, but some of us will have a more attractive signature than others. You can line up 10 people and have each place one arm in a cage containing hundreds of mosquitoes. A few arms will quickly resemble a shag rug because of all the mosquitoes that have landed to feed. Yet others will have just a few mosquitoes in temporary residence, and a few arms will be nearly untouched. To further complicate matters, a person who is highly attractive to females of one kind of mosquito may not necessarily be as attractive to mosquitoes of other species. Folks often ask whether they should befriend someone who is more - or less - attractive (to mosquitoes). The notion is that sitting next to a person who is more mosquito-attractive will somehow protect you by diverting mosquitoes from you to him/her. Genius, but the two of you together may draw in even more mosquitoes, and you may suffer even more bites than if you were a lone soul on the park bench. Ah, but what about sitting next to a mosquito-repellent person? That still may not benefit you. Certain emanations of that person may draw in mosquitoes from afar, but they then might home in on you once they were close.With all this said, there is the concept of zooprophylaxis. Maintaining chickens, goats or other animals in your home can, in some cases, divert bites by mosquitoes that would otherwise have been directed to a person. This can afford some limited protection against malaria and other mosquito-borne infections. Whereas this may offer a strategy for folks who live in primitive dwellings in rural regions and don't have resources to protect themselves by way of improved housing, pesticides, etc, it would not likely be embraced by travelers. Imagine checking in your hotel and finding a complementary chicken in the room. Ah, but if it was a rooster, you'd not need to set the alarm clock.
What can cause my skin to itch and severely bruise after scratching, I am not on any drugs?
I don’t know but I looked it up and I think Dr Bhupinder’s answer is best.HELP- itchy skin and bruisingEveryone is right about seeing the doctor. Take pictures of the bruises to show the doctor in case they are gone or markedly changed before you get there. Also take close up pictures of your skin when it's itchy and before the bruise forms.it never hurts to get more than one opinion from a Doc.Dont hesitate, go check it out.
My 4 yr old bearded dragon is molting. Is this a seasonal thing? Should I be giving her more water?
Wow! Someone really likes to copy and paste! Anyways... Bearded Dragons aka Pagonas shed alot as they grow. The underneath skin is her natural color of which can be one of many different shades. I am concerned about what you are feeding her and that she laid eggs recently. Lettuceis a no no in reptiles/herps. You should feed her a mixture of bright colored fruits and veggies such as Kale, squash, collards ect.. She should also have a high protein diet such as a variety of crickets and worms(Ive been told no superworms because of their fat content, but as a rescuer I need to bulk my herps up when they get here because they are usually underweight.). Occasionally for my thinner dragons I feed a small mouse for calcium and fat, this is controvercial and I will hear some crap for it, but underweight animals are a big problem. She also needs alot of calcium after laying those eggs. I hear of alot of female herps dying from calcium definciencies after laying eggs and not being properly cared for. So dont worry about the shedding/molting, its a good thing it shows she is growing. My 6 year old beardie still does it. I hope this information helps.
