being bitten. I then purchased a product called dietomaceus earth which is available at plant stores (Art Knapp). It is chemical and odour free and has the consistancy of talcum powder - very easy to use. It sticks to the waxy outer shell of the bugs and dehydrates them and kills them. It is safe enough to sprinkle into your bed sheets. My landlord (Jordan Developments) has told me that bed bugs don't spread through the building but that they are spread by the tenants themselves. I have not been bitten since Oct. 14th so I assume my suite is bed bug free. I never want to go through that again. The bites are very nasty and I suffered nerve toxicity as well.
