The invention discloses an attapulgite maggot killing agent, which has the technical scheme that the attapulgite maggot killing agent is composed of pasty attapulgite clays, pyrethrum, oleander, peach leaves, neem nuts leaves, sodium carboxymethylcellulose and deionized water. After stirring, the ingredients are ground and pulped into a mixture. The mixture is ground into a pasty mixture, and is canned to obtain the finished product of ttapulgite maggot killing agents. The attapulgite maggot killing agent has higher viscosity, can adhere onto the outer surface of fly spawns, maggots and pupaswhen sprayed in breeding grounds of fly spawns, maggots and pupas, facilitates permeating into the bodies of fly spawns, maggots and pupas, and can improve the effects of killing fly spawns, maggots and pupas. The attapulgite maggot killing agent can not generate any damage to human bodies and livestocks, is safe and health, can be naturally degraded, and can not pollute the environment. Therefore, the attapulgite maggot killing agent is for killing fly spawns, maggots and pupas.
