Soap Spray. A mixture of mild liquid (or dish) soap mixed with water creates a simple yet powerful organic pest control that works by suffocating soft-bodied pests like aphids, whiteflies, and mites.
Pesticides vary in their effects on bees. Contact pesticides are usually sprayed on plants and can kill bees when they crawl over sprayed surfaces of plants or other areas around it. Systemic pesticides, on the other hand, are usually incorporated into the soil or onto seeds and move up into the stem, leaves, nectar, and pollen of plants. [1] [2]
Neonicotinoid use has been linked to adverse ecological effects, including risks to many non-target organisms, and specifically on bees and pollinators. [9] [11] [12] A 2018 review by the European Food Safety Authority (EFSA) concluded that most uses of neonicotinoid pesticides represent a risk to wild bees and honeybees.
Insecticides are pesticides used to kill insects. [1] They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, industrial buildings, for vector control, and control of insect parasites of animals and humans.

Imidacloprid is more toxic to bees than the organophosphate dimethoate (oral LD 50 152 ng/bee) or the pyrethroid cypermethrin (oral LD 50 160 ng/bee). [34] The toxicity of imidacloprid to bees differs from most insecticides in that it is more toxic orally than by contact. The contact acute LD 50 is 0.024 μg active ingredient per bee. [35]
