園藝店裡有賣這種螳螂泡巢,不便宜(@CDN$16.99+HST)可是很有效! 不但控制一般害蟲也使得蛞蝓和蚊蠅明顯減少,不需噴藥卻可以高枕無憂再不怕玫瑰被蹂躪了,真好!  用了好用也介紹給鄰居和客戶使用—大家也說好讚又環保.

Here is an article from http://www.thecanadianencyclopedia.com/articles/mantid

—-Three species of mantids are recorded in Canada. The praying mantid (Mantis religiosa) was introduced accidentally from Europe to New York, US, in 1899 and subsequently spread to southern Ontario and Quebec. It was later introduced to the Okanagan Valley, BC, to control grasshoppers. The eggs are laid in a frothy substance that hardens into a case and glues the eggs to a twig, fence post or other support. The eggs overwinter and hatch in the spring; adults appear in the late summer.

The Chinese mantid (Tenodera aridifolia) was introduced to eastern North America from China in 1896 to control INSECT PESTS. The ground mantid, (Litaneutria minor) ranges from Mexico north to BC, and is the only native Canadian mantid. In Canada it is known only from the dry grasslands of the southern Okanagan Valley. The males are winged; females are flightless but are agile runners.
