Deadly or Not? Busting the Poinsettia Myth

Dec 2, 2011   //   by Bettina Weber   //   News & Reference  //  No Comments

Can you believe it’s December already? Candy canes, twinkly lights and bow-topped gifts abound. But before we bring out the eggnog, it’s high time we clear the air about one type of holiday décor that has gotten a pretty bad rap: the poinsettia.

Believe it or not, pet parents, these festive plants are not the deadly flowers legend has made them out to be. The myth of the plant’s toxicity actually began in the early part of the 20th century, after the two-year-old child of a U.S. Army officer allegedly died from consuming a poinsettia leaf. As a result of this rumor, the plant has never lived down its poisonous reputation.

Okay, so you still don’t necessarily want your pets to eat them. Because consuming poinsettias may cause mild gastrointestinal irritation, keeping these plants out of pets’ reach is still a good idea. But there’s no need to banish them altogether.

So, what do you say? Let’s give this plant a break—I hear they make quite the centerpiece.

More mosquitoes this summer – are they attracted to you?

Why some people are mosquito magnets

By Cari Nierenberg

Some folks seem to be magnets for mosquitoes, while others rarely get bitten. What makes the little buggers single you out and not the guy or gal you’re standing next to at the Memorial Day backyard barbecue?

The two most important reasons a mosquito is attracted to you have to do with sight and smell, says Jonathan Day, a professor of medical entomology at the University of Florida in Vero Beach. Lab studies suggest that 20 percent of people are high attractor types, he says.

Mosquitoes are highly visual, especially later in the afternoon, and their first mode of search for humans is through vision, explains Day. People dressed in dark colors — black, navy blue, red — stand out and movement is another cue.

Once the mosquito keys in on a promising visual target, she (and it’s always “she” — only the ladies bite) then picks up on smell. The main attractor is your rate of carbon dioxide production with every exhale you take.

Those with higher metabolic rates produce more carbon dioxide, as do larger people and pregnant women. Although carbon dioxide is the primary attractant, other secondary smells coming from your skin or breath mark you as a good landing spot.

Lactic acid (given off while exercising), acetone (a chemical released in your breath), and estradiol (a breakdown product of estrogen) can all be released at varying concentrations and lure in mosquitoes, says Day. Your body temperature, or warmth, can also make a difference. Mosquitoes may flock to pregnant women because of their extra body heat.

But with more than 350 compounds isolated from odors produced by human skin, researchers have barely scratched the surface behind a mosquito’s preference for certain people, says Joseph Conlon, a medical entomologist and the technical advisor to the American Mosquito Control Association.

Although it may all boil down to human odor and genetics — studies of twins have revealed they tend to be attractive or repellant to mosquitoes in the same measure — it’s more complicated than that, suggests Conlon.

He says the latest thinking is that it might not be about what makes people more attractive to mosquitoes, but what makes them not as repellant. It could be that individuals who get less bites produce chemicals on their skin that make them more repellant and cover up smells that mosquitoes find attractive.

Mosquitoes don’t bite you for food, since they feed off plant nectar, Conlon explains. Females suck your blood to get a protein needed to develop their eggs, which can then send more pesky insects into the world to annoy you.

But keep this in mind when you’re outdoors this summer: Mosquitoes are more attracted to people after they drink a 12-ounce beer. It could be that people breathe a little harder after a cold one or their skin is a little warmer, suggests Conlon. But that won’t stop him from having a brewski, even though he considers himself a mosquito magnet.

Here are more fun facts about mosquitoes and bites provided by our experts:

  • Eating bananas will not attract mosquitoes and taking vitamin B-12 will not repel them; these are old wives’ tales.
  • Some mosquito species are leg and ankle biters; they cue into the stinky smell of bacteria on your feet.
  • Other species prefer the head, neck and arms perhaps because of the warmth, smells emitted by your skin, and closeness to carbon dioxide released by your mouth.
  • The size of a mosquito bite welt has nothing to do with the amount of blood taken and everything to do with how your immune system responds to the saliva introduced by the mosquito into your skin.
  • The more times you get bitten by a particular species of mosquito, the less most people react to that species over time. The bad news? There’s more than 3,000 species worldwide.
