The number of cockroach infestations reported in the lower mainland last year rose by nearly 69% according to figures recently released. This is the twelfth year in a row in which pest control companies have seen a rise in the number of complaints received relating to these pests in B.C. Cockroaches pose a risk to human health and we all have the responsibility to look for signs of an infestation. The growing popularity of imported food, together with a growth in foreign travel and overall warmer weather conditions have contributed to the rise of these hardy blood suckers here. Cockroaches carry intestinal diseases such as diarrhoea, dysentery, typhoid fever, and cholera. People who are in contact with cockroaches may develop mild to severe allergic reactions such as dermatitis, itching, swelling of the eyelids, and serious respiratory conditions. Common signs of a cockroach infestation include an unpleasant odour, shed skins and feces.
