It is possible to capture and exterminate insect pests attracting and attracting insect pests such as mites such as wakumo and trismus etc., fleas and the like, and provide a pest accumulation device that anyone can handle easily. An accumulator 11 having a porous structure having a large number of pores 11 h continuous from the surface to the interior thereof, and the accumulation section 11 has a pore diameter of the hole 11 h D is formed to a size that allows insects or the like to invade. Since the accumulating section 11 has a large number of holes 11 h formed continuously from the surface to the inside thereof and formed to have such a size that pests or the like can enter, the hole 11 h becomes a hiding place such as pests and the like. Therefore, If the pest accumulating device 1 is arranged at a predetermined place in the poultry house CH, a part of insect pests parasitizing on the chickens, etc. and insect pests or the like which have entered the gaps such as poultry houses CH and chicken cages KG, You can collect in 11.ワクモやトリサシダニ等のダニ類やノミ類などの害虫等を誘引しかつ誘引した害虫等を捕捉しかつ駆除することができ、誰でも簡単に取り扱うことができる害虫集積装置を提供する。 ダニ類やノミ類などの害虫等を集積する装置であって、表面から内部まで連続する多数の孔11hを有する多孔質構造の集積部11を備えており、集積部11は、孔11hの孔径Dが、害虫等が侵入しうる大きさに形成されたものである。集積部11は、表面から内部まで連続しかつ害虫等が侵入し得る大きさに形成された多数の孔11hを有しているので、孔11hが害虫等の隠れ場所となるしたがって、本発明の害虫集積装置1を鶏舎CHの所定の場所に配置すれば、鶏に寄生している害虫等や、鶏舎CHや鶏のケージKGなどの隙間に侵入していた害虫等の一部を、集積部11に集めることができる。
