The question is toxic to what. Not all chemicals which are toxic to humans are toxic to bacteria, and some chemicals which are toxic to bacteria are harmless to humans (which is why we can have antibiotics). There are chemicals (like Hydrogen Sulfide) which are very toxic to mammals that SOME bacteria eat as food. But there are other chemicals like chlorine which are toxic to both humans and bacteria. So the question does not have a simple answer.
The Australian plant Kangaroo paw is not toxic to humans or animals.

Pyrethrum is produced from the herb feverfew. Pyrethrum does kill ants and other insects by producing a toxic effect when it reaches the insects nervous system.
Pyrethrum is used as a pesticide.

Pyrethrin insecticide, pyrethrin spray, pyrethrin fogging products, pyrethrin foggers.Enviornment-Safe Pyrethrum Pyrethrum is a completely organic, environment-safe insecticide derived from 100% African Chrysanthemum flowers. Pyrethrum powder is toxic to ants, roaches, silverfish, bed bugs, fleas, wasps, spiders, crickets, mosquitoes, and just about every other category of unwanted house or garden pest. Because it decomposes rapidly in the environment, pyrethrum has been approved for a wide range of indoor and outdoor uses, including homes, restaurants, broad-scale spraying operations, and organic farms.In addition to being environment friendly, pyrethrum also has the following unique properties: * Quick Action -Pyrethrum poisons insects upon contact, attacking the central nervous system and resulting in faster knockdown and kill. * Low Toxicity - Pyrethrum is one of the least toxic insecticides available, boasting a long history of proven safety towards humans and animals. * Repellent - When not present in fatal amounts, pyrethrum acts as a repellent to protect food establishments, grain storage, and crops from insect pests. * Flushing Agent- Pyrethrum agitates insects in their hiding places, flushing them out and forcing them to be exposed to the insecticide. * Multi-purpose - Pyrethrum consists of a group of compounds rather than a single compound, resulting in a wider scope of activity against pests than other insecticides. It can be used against almost any pest in the house or garden. No Insect Immunity - Insect resistance is not a problem because of the complexity of the molecule that pyrethrum is composed of.

the chemical pyrethrum is extracted from chrysanthemum flowers. the chemical is toxic to the bug. however, the actual flower itself is not likely to be an effective toxin as the dosage and application are not appropriate.
No
