Mothballs and other toxic pesticides

When it comes to synthetic pesticides, the less you use the better, and best is using none at all. Labels can't be relied on for safe usage advice. Take mothballs.

At the March 2010 meeting of the American Chemical Society, Linda Hall, a scientist with the California Environmental Protection Agency, presented a new study about the misleading nature of pesticide labels. She was focusing on mothball products and noted that, while companies tell you the minimum amount yper square footage ou should use for their products to be effective, they are loathe to tell you how much is too much. No maximum number of mothballs is noted.

The labeling info gap, Hall said, leads people to think that if a little bit is good, a lot is EVEN BETTER! But this is clearly not a good idea when it comes to hazardous ingredients in mothballs such as carcinogenic
naphthalene
, and para-dichlorobenzene (pDCB; the latter has been found in extremely high levels in homes across California, as well as the rest of the country, Hall reported.

Labels also fail to provide safety information about the need to air out mothballed clothes before wearing them. This should be done, just as with conventionally drycleaned clothes, which release vapors of toxic perchloroethylene.

For less toxic pest control, leave mothballs and insecticides on the store shelf, and find safer ways to keep bugs away. Synthetic pesticides are hazardous in any quantity and can trigger asthma and allergic reactions, and they've been linked to childhood leukemia, Parkinson's disease, autism, and a wide array of other chronic illnesses. A recent study at Stanford University suggested that pesticides can interfere with the way your body produces insulin, possibly leading to type 2 diabetes).

Keep moths away from your clothes by cleaning them before putting them away, and sealing them in airtight containers. If a few moths do happen in, put clothes in plastic bags and shove them in the deep freeze for three days to kill eggs, or air them out in sunlight. Here are more non-chemical mothproofing tips.

For general pest control, boric acid powder and diatomaceous earth are two less toxic products that work by rubbing off a bug's waxy outer shell. They don't have any impact on humans unless directly ingested. For more tips, check out
