Childhood cancers continue to be a bit of an enigma in the medical community. As one expert in this piece points out, most ‘just happen’ without being attributed to a specific cause. But there may be one area that parents can be extra vigilant about: the chemicals being used in and around their home.

A recent study that analyzed data over the past decade found that pesticide exposure put kids at a greater risk of developing two types of blood cancer, leukemia or lymphoma. For indoor insecticides, this risk was as high as 47 percent while weed killers presented a 26 percent risk. "We don't know 'how much' exposure it takes, or if there's a critical window in development," said senior researcher Chensheng (Alex) Lu, an associate professor of environmental exposure biology at the Harvard School of Public Health in Boston.

That said, it might be time to eschew the chemicals and opt for more natural bug-repellent methods (For example, bay leaves repel ants, moths and roaches while dabbing eucalyptus oil around windows and door frames will ward off spiders). What are some chemical-free ways you pest-proof your home and yard?
