在房屋仓库中进行防治白蚁工作,往往由于对它们的结构特别是地下情况弄不清楚,使药剂的效果受到很大的影响,因此必须考虑用诱杀法来消灭白蚁。 (一)在什么情况下决定做诱杀坑 在有白蚁的地方如果经过多次施药仍未见效又无法找到蚁巢,就得分析产生这种原因的各个因素:建筑物的基地可能埋藏棺木、树头没有清除而成了蚁巢;建筑时遗留下多量零碎木材埋入地下;建成后常堆放带有白蚁的物品经久不加清理,白蚁因需水分已有相当一部分钻入土中,但当清除物品时又未进行过药物处理;因房屋受白蚁蛀蚀损坏而进行拆修时惊动白蚁大量逃向地下等等。由于以上原因白蚁多从地下钻出为害。对于这些情况作充分调查研究后便可决定做诱杀坑。 Termites are often used in house warehouses to prevent and control termites. However, their effectiveness is greatly affected by the fact that their structures, especially subsurface conditions, are not clearly understood. Therefore, the use of trapping and killing methods to eliminate termites must be considered.

Due to the above reasons termites and more from underground drilling damage. After making a full investigation of these situations, you can decide to make a trap.
