Pesticides

Material A
Fatty Acids, also known as insectidical soap. This choice is probably the most environmentally friendly. Not only do they repel insects, they are also safe for consumption.

Disposal: This type of pesticide can most likely be placed in your green bin, however, it is safer to bring this to a drop-off depot as it is technically considered household hazardous waste (HHW).

Material B
Various chemicals. Chemicals such as propane, isobutane, imiprothrin, and alkanes are sometimes used in conjunction to provide a spray for killing small pests and insects.

Disposal: These chemicals are considered household hazardous waste (HHW) and must be taken to a drop-off depot to be disposed of correctly. Do not place these chemicals in any bins or in any drains or sewers.

Material C
Aerosol Canister. These are usually made of a strong metal to contain compressed chemicals.

Disposal: If empty, the canister can be recycled. If not, the canister must be taken to a drop-off depot as it is considered household hazardous waste (HHW).

Best Alternative
The optimal solution is to search for a pesticide that is organic and will not harm your plant life or inhibit the ability to eat them if that is the intended purpose.
