Which product is specifically formulated to control insects?

Insecticides are specifically formulated to target and control insect populations. They are designed to be effective against a variety of insects, including pests that may damage crops, lawns, and ornamentals. By disrupting the biological processes essential for insects’ growth and reproduction, insecticides can reduce the overall population and prevent further damage.

Horticultural oils, while useful for controlling insects and diseases, are not solely formulated for one specific class of pests; they work primarily by suffocating insects or inhibiting their growth, but they may not be as effective against a broad range of insect species as insecticides. Implantable capsules are typically used for other purposes, such as delivering nutrients or medications rather than for managing insect populations. Honeydew is a byproduct of aphids or other sap-sucking insects and is not a control product but rather indicates the presence of pest problems.

Thus, insecticides are the most appropriate choice for the given question as they are the direct solutions designed for insect control.
