Answer 2

1. Systemic

The most common application for systemic insecticides is through soil drenching. The insecticide is introduced into the soil where it is absorbed by plant roots. It then moves up through the plant to external areas (leaves, twigs, fruits, branches), where it lays on the plant surface area and is poisonous to any insects that come chewing on the plant.

2. Contact

Contact insecticides act like “bullets” aimed at a target and can only kill insects that are hit by its application. Common household insect spray acts much like a contact insecticide. Because this type must directly hit the insect, it is ineffective as a preventative insecticide.

3. Ingested

Many other common household pest control substances are ingested insecticides that are placed throughout the home where insects will ingest the poison. Typical rat and roach poisons are ingested insecticides that are available everywhere from supermarkets to convenience stores.
