What pests are contact insecticides effective against?

• A. Only chewing insects
• B. Only sucking insects
• C. Both chewing and sucking insects (small and large)
• D. Only mites

Answer: (C)

Contact insecticides work by killing pests on contact with the chemical, not by requiring the insect to eat it. Because the product affects the insect’s body upon touch, it can protect plants against both chewing pests (which bite and chew plant tissue) and sucking pests (which feed on sap) as long as they come into contact with the treated surfaces. This means it can affect small and large life stages that encounter the residue. For best results, ensure thorough coverage of the plant surfaces where pests move and feed, and apply when pests are active and exposed. While some products may also target mites, the general idea is that contact insecticides are effective against a broad range of pests that contact the treated area, including both chewing and sucking types.
