A. Acetamiprid

This toxic pesticide belongs to a class of synthetic chemicals similar to nicotine. It is a broad-spectrum insecticidal treatment to combat a variety of insects.

B. Carbamate

This chemical is used in the form of spray or dust. It works by affecting the brain and the nervous system of the spider when sprayed or dusted on.


Skin contact with carbamate causes a minor rash. Prolonged exposure may result in more severe symptoms that include nausea. Caution is advised.

C. Permethrin

This is used in the form of dust, spray, and foggers. It is a pyrethroid insecticide that is found naturally in chrysanthemums. It is a relatively non-toxic to moderately toxic pesticide, depending on the amount used.

D. Pyrethrins

This is used in dust, foggers, and aerosol sprays. Since it is a natural insecticide derived from chrysanthemums, it poses low toxicity to mammals while having a potent effect on spiders.
