I dont think anyone answered your question bout bugs? U mentioned "BP" what youre actually referring to is BT whos scientific name is
Bacillus thuringiensis. (All info taken from wikipedia, check the sources yourself) Spores and crystalline insecticidal
proteins produced by
B. thuringiensis have been used to control insect pests since the 1920s.
[11] They are now used as specific
insecticides under trade names such as Dipel and Thuricide. Because of their specificity, these
pesticides are regarded as
environmentally friendly, with little or no effect on
humans,
wildlife,
pollinators, and most other
beneficial insects.
B. thuringiensis-based insecticides are often applied as liquid sprays on crop plants, where the insecticide must be ingested to be effective. It is thought that the solubilized toxins form pores in the midgut epithelium of susceptible larvae. Recent research has suggested that the midgut bacteria of susceptible larvae are required for
B. thuringiensis insecticidal activity.
So BT is good and alot of people use it.
And onto Spinosad :
Spinosad (spinosyn A and spinosyn D) are a new chemical class of
insecticides that are registered by the
United States Environmental Protection Agency‎ (EPA) to control a variety of insects. The active ingredient is derived from a naturally occurring soil dwelling bacterium called
Saccharopolyspora spinosa, a rare
actinomycete reportedly collected from soil in an abandoned rum distillery on a Caribbean Island in 1982 by a scientist on vacation.
[1] It has not been found in nature since that time, and was subsequently described as a new species.Spinosad kills susceptible species by causing rapid excitation of the insect
nervous system. Due to this unique mode of action, Spinosad is valued in resistance management programs. Spinosad must be ingested by the insect, therefore it has little effect on non-target predatory insects. It is highly effective used as an oral anti-flea medication for dogs, and apparently has the potential for killing any blood-sucking insect. Spinosad is relatively fast acting. The insect dies within one to two days after ingesting the active ingredient. There appears to be 100% mortality.
It is used to control a variety of insect pests, including
fruit flies,
caterpillars,
leafminers,
thrips,
sawflies,
spider mites,
fire ants, and
leaf beetle larvae.
Spinosad does not significantly affect
beneficial organisms including
ladybugs,
green lacewings, minute
pirate bugs, and predatory
mites.
Spinosad shows low toxicity when ingested by mammals (male rat
LD[SIZE=-1]50[/SIZE] = 3738 mg/kg) and no additional adverse effects from chronic exposure. Studies on spinosad show slight toxicity to birds, moderate toxicity to fish, and slight to moderate toxicity to aquatic invertebrates. However, it is highly toxic to bees (honey bee
LC50 = 11.5 ppm) and is highly toxic to oysters and other marine mollusks. Applications to areas where bees are actively foraging should be avoided. After the residues have dried, it is much less toxic to bees.
That was spinosad. Very effective i'd say.
Ill add one more to the list and this is the product that I use with great success and also another organic insectiside. It's called
Azadirachtin, and marketed by general hydroponics company as Azamax. Heres the info. :
Azadirachtin is a
chemical compound belonging to the
limonoids. It is a
secondary metabolite present in the
neem tree seeds. It is now known to affect over 200 species of
insect, by acting mainly as an antifeedant and growth disruptor, and as such it possesses considerable toxicity toward insects. It fulfills many of the criteria needed for a natural
insecticide if it is to replace synthetic compounds. Azadirachtin is
biodegradable (it degrades within 100 hours when exposed to light and water) and shows very low
toxicity to
mammals (the
LD[SIZE=-1]50[/SIZE] in rats is > 3,540 mg/kg making it practically non-toxic). This compound is found in the seeds (0.2 to 0.8 percent by weight) of the
neem tree,
Azadirachta indica (hence the prefix aza does not imply an
aza compound, but refers to the
scientific species name). Many more compounds, related to azadirachtin, are present in the seeds as well as in the leaves and the bark of the neem tree which also show strong biological activities among various pest insects
[2][3] Effects of these preparations on beneficial arthropods are generally considered to be minimal. Some laboratory and field studies have found neem extracts to be compatible with biological control.
So thats a light reading on these thre differrent insectisides. Whichever you choose will work very well as long as they are applied correctly. I only prefer using Azadirachtin (azamax) because of the great number of insects it kills and the fact that it not only kills the mature insects on contact but after they feed on my plant which was treated they will then return to their larva infecting them with the azadirachtin and prohibitng the larva from maturing into the bugs we all hate.
Hope this helps hit me up with any questions! RDG
