Iimali ezongezelelweyo ezixhunywa kwiiNgqungquthela zonyaka
Ama-ladybugs ase-Asia (i- Harmonia axyridis) ayetyenziswe ngokufanelekileyo e-United States ekuqaleni kwekhulu lama-20 njengendlela yokulawula izilwanyana.

Ngomnyaka we-1980, abantu baseAsia babekhulile kangangokuthi abaninzi beendawo zasemaphandleni nasemaphandleni baqalene nokuhlaselwa kwezindlu ezinobungozi kunye nezingozi.
Namhlanje, ezi zigulo ziye zabikwa zonke kwi-East Coast ukuya ngasezantsi njengeGeorgia nakwiizwe ezifana neWisconsin, eKentucky, eMissouri naseWest Virginia. Ezi zifikile iingxelo ukuba abantu baqalise ukuphucula ukunyuka kokuphendula ngokuthe ngqo kwezi zidalwa ezingezona zendalo.

Ngokomphando, i-Asian ladybug ikhiqiza ikhemikhali ebizwa ngokuthi i-isopropyl methoxy pyrazine (i-IPMP) eyisebenzisayo ukukhusela iintshaba. Ikhemikhali ibonakala "kwigazi" leengambuzane (elibizwa ngokuba yi-hemolymph) elikhuphayo xa likhupha. Inkunkuma ayinayo kuphela iphunga elimnandi (elifana nelinye leentaka ezimanzi), lishiya umbala obonakalayo, owenziwe nge-orangish onfaces and fabrics.

Ukongezelela kwi "reflex bleed", i-ladybugs ingaluma abantu, mhlawumbi ukuba ityule ekhumbeni.

Ukuba kukho iibhugi ngaphakathi kwindlu, sebenzisa i-vacuum cleaner esikhundleni se-broom ukuyiqokelela. Ukugaya kungabangela ukuphuma kwegazi. Ukongeza, faka i-nylon ukubeka phezu kwipahla yokucoca i-vacuum ukuyikhupha ngaphandle kokuvumela ukuqokelela ngaphakathi kumatshini. Ngaloo ndlela, unako ukuwachitha ngokukhawuleza kunye nokugqithisa okuncinci. Geza izandla zakho ngesepha efudumele kunye namanzi emva koko.
