Many people in the Pacific Northwest don't come into contact with roaches unless they work in an infested restaurant or live in an infested apartment building. Their experience is often limited to a vacation trip to Hawaii or Mexico where roaches are common in plantings on the outside. If you do live in an infested area, however, there is increasing evidence that some of your allergies may be related to roaches.
And,even if you have no direct contact with these insects you may have allergic reaction because of tiny insect parts in the food you eat. ABC News recently reported there was an average of 8 insect parts found in the average chocolate bar and it was deemed safe according to FDA guidelines. Trace amounts of insect parts ground up in food can affect people with allergies and asthma, and with side effects that include migraine, cramps, itching and hives. Not a pleasant thought, but, it does emphasize why good sanitation and preventive pest control is important - not only in food plants, but in our homes as well.
