Don't Bug Out: How to Get Rid of Pests without Pesticides Posted on May 1, 2009 0 Comments Source: http://blogs.nationalgeographic.com/blogs/thegreenroom/ It's not just baby animals that emerge in spring: A whole host of insects that can eat you out of house and home also come out of the woodwork. Applying indiscriminate amounts of pesticides used to be the norm, but more environmentally sensitive ways to combat pests have cropped up in recent years. Here's a primer for how to take on the toughest bugs: Cockroaches First of all, make sure your kitchen and the areas underneath your sinks are completely clean, with no food bits that would lure roaches. One of the most effective natural control methods for roaches is boric acid--a white, organic powder that is deadly to these insects, but is no more toxic than table salt to humans.

The study's authors modeled how far different classes of cars could go based on the available energy from a unit of land and found that bioelectricity--burning biomass to make electricity--far outperforms ethanol. The paper, published on Thursday in Science, found that bioelectricity delivered 81 percent more distance per unit area of crop land than ethanol. Greenhouse gas emissions per area of land were 100 percent less than cellulosic ethanol. (Click here for PDF of results.) In one example, they found that a small truck powered by bioelectricity could travel almost 15,000 miles compared with 8,000 comparable miles for an internal combustion equivalent.
