@@fileinterrupted1787 it's an irritant so use gloves but aside from that it's perfectly safe for humans and animals. I'd recommend using the spray, mid july, late August and mid September. 3 sprays on any brassicas or other susceptible plants should keep them safe for the season :)
You have such a soothing voice ☺️. A very informative video. I just got some wet table powder BTI (for bottom watering). My house plants had gnats recently but I was able to get rid of them and I’d like to prevent any potential larvae from emerging. Can this be diluted in water with some fertilizer or should it be water only? Thank you for sharing your knowledge!
How do you get it to stick to the leaves? Every time I spray it it just beads up. I end up having to apply it with a small paint brush. That takes forever.
Help, what can I use on my ferns. I see little pellets on my porch underneath my baskets, and some of the stems are bare. Last year I picked off green and black catapillars. I buy new ones every year.
If you know for sure that it is caterpillars then use BT. I get a brand called "Monterey BT " but Safer brand is also effective. BT is a LIFESAVER from caterpillars! Find out what is eating them for sure and then you'll know what to spray!
Was that a vegetable you were using for your demonstration? I have some 16 Oz spray bottles which I was going to use and conserve on my waste. How would you recommend my mixing ratio? Thx, good video.
It was an ornamental plant. The correct mixing ratio can be found on the label of the product you are using. Even with one chemical the mixing ratio can vary based on the concentration of the product and the plant you are using it on.
@@FamilyPlotGarden thank you for the speedy reply. I just did my first spray last night, I've read 7 days after for the second application, but we have rain in the forecast. Will it wash the btk away or am I good to go?
Mentioned some affect on plants. What are the signs? What are all negative side effects to using this? Plants and insects alike. Any affect on animals?
The affect on the plants is that the caterpillar must eat some of the plant that has Bt on it. So you will have a very small amount of insect damage. once the caterpillar ingests the Bt it will almost immediately stop feeding and die. The Bt is a stomach poison to caterpillars. It does not have any affect on humans or other mammals or other animals. With any other insecticide you need to make sure you are applying the correct pesticide for the problem. Also, be aware that you need to be aware of what you don't want to kill. For example, if you are trying to grow milkweed for monarch butterflies don't put Bt on the milkweed. It will kill the monarch caterpillars.
It depends on the product you have. The label will have that information. Often the amount will be based on an area, so you need to figure out how much spray will cover the plants in that area and mix accordingly.
Bt can be used on lawns to kill caterpillars. It will not hurt the lawn. Read the label for information about how much to use. The label may also say not to use it when the sun is shining to avoid burn. Always read and follow the label.
Does it kill any other insect/pests? Or just caterpillars? Where does BT come from ? Is it in milk? Do you know what the e.c means on the pesticides ? Thanks
From cucurbitan…..the bitter toxins in bitter gourds. It causes nausea, diarrhea and can kill humans. Look up bitter gourd poisoning. You will also get sick of it is not washed off properly because it can leach into the soft flesh of fruits. So don’t use it on tender skinned things like berries or beans or the foods you eat the skin of as a precaution. Soaking your veggies in water can leach a good portion of the toxins from the skins. Will it prevent bugs from eating it? Yes. Can it also make you sick? Yes. My suggestion is to plant your own bitter gourds and make your own without any processed chemicals. It comes from the juice and it’s so bitter that one gourd will go a very long way. Just make sure you wash the skins off and leave them to soak in some water until they are sweaty clean. You always notice a film on home grown veggies. Make sure they squeak. Remember that this is a poison, but a natural one used in nature to deter pests from eating the gourds when the seeds are viable. It’s the cold season now……go buy some gourds to use next year and save the seeds so you have your own supply. Good luck to you all as we try and provide the best for our lives and families. Remember that people lie…..it is just as toxic to humans as to bugs without precautions. Think of it like soap….because in some cultures it is used as soap. You must wash it off.
Bt kills caterpillars, but it does not kill other insects. Bt (Bacillus thuringiensis) is a bacteria that produces a protein that is activated in the high pH gut of a caterpillar. The protein then breaks down the digestive tract of the caterpillar which causes it to die. There are several strains of Bt. Another strain is used to kill mosquito larvae. Here is an info sheet from the National Pesticide Information Center that has a lot more information: npic.orst.edu/factsheets/btgen.html
BT can be purchased at any nursery or big box home improvement center. It might be sold under a trade name so you will have to read the ingredients list. One common trade name is Thuricide.
it only kills caterpillars but i like the ones that become beautiful butterflies... will it kill them too or do they live somewhere else and wont get sprayed?
Carpenter ants are hard to control. The insecticide needs to be applied inside the nest. Baits can be effective, but they are of limited use. It is probably best to hire a licensed pest control company that has experience with carpenter ants. Here is a publication by University of New Hampshire Extension that goes over some of the details: extension.unh.edu/resources/files/Resource000530_Rep552.pdf
It does. The great thing though is that caterpillars only seem to do one thing in life: eat. If the Bt was on the plant for only a few hours any caterpillar that has been feeding on the plant has ingested some.
You can. The insecticide label probably has the amount you have to put in a gallon. You would just need to do some math to adjust that to the size of your spray bottle.
To figure out how much to use read the label on the side of the BT bottle. Different manufacturers have different concentrations so there is no one set amount to use.
Do they also eat the tomatoes too? Two years ago I spotted these scary looking Horned Tomato Caterpillars and also saw them in the “super sized” Moth stage! 😳 I didn’t really see a lot of damage to the leaves but they literally feasted on my tomatoes! Or... do you think there were “2” culprits? Last year I didn’t plant anything but my Great Grand Daughter found one along the far side of my house & ever so sweetly brought it to me! 😂 I do have wild Strawberries growing around the entire foundation of my home. Any advice would be greatly appreciated. I honestly miss my tasty home grown (on my deck) delicious tomatoes & I’m not willing to share with these critters! 🤗 {{{ HUGGZ }}} from North East Ohio; ~Su
The horn worms usually don't eat the fruit but they will defoliate a tomato plant in a day or two. Other worms do like the fruit like the tomato fruit worm and corn earworm. All of them are effectively controlled by BT. I just watch for damage or the horn worms' telltale droppings - they look like small hand grenades - then spray. If I think there is only one I will just find it and pick it off.
Why bother to spray the underside of the leaf? When the caterpillar eats the leaf it eats both the top and bottom.
I am currently doing a Microbiology semester paper over this bacteria. Interesting video!
is it safe for humans

If not what are your thoughts of putting it sprayed on your food AS something you wanna sprinkle on your popcorn
Can you use this in hot temperatures? Texas temps hit upper 90s starting in June.
Will it kill leaf miners on citrus?
You say "it does not adversly effect humans so, it does effect them just not adversly ... Thanks good to know!¬

@@FamilyPlotGarden my question is will bt spray wash off in the rain.
@@jasonclayton936yes And sun also degrades it Reapply weekly or less
What time of day is the best to spray btk? I am protecting oaks and maples up in ontario, and I have heard sunlight breaks the bacteria down. Thanks!
You should be able to spray anytime. The bacteria is not what kills the caterpillars. It is the toxins the bacteria produce.
@@FamilyPlotGarden thank you for the speedy reply. I just did my first spray last night, I've read 7 days after for the second application, but we have rain in the forecast. Will it wash the btk away or am I good to go?

@@FamilyPlotGarden is there any study done on affects of nearby animals or birds?
If your garden is in full sun do you have to rinse this off? Im just worried it may burn my plants
Bt should not burn plants. To be safe read the label and see if it gives directions on times of day to use the product.
Dude . What's concentration per 1 litre...if I have liguis BTi??pls
It depends on the product you have. The label will have that information. Often the amount will be based on an area, so you need to figure out how much spray will cover the plants in that area and mix accordingly.

It kills all caterpillars so you have to make sure you are not applying it to a plant being eaten by a "good" caterpillar.

It does. The great thing though is that caterpillars only seem to do one thing in life: eat. If the Bt was on the plant for only a few hours any caterpillar that has been feeding on the plant has ingested some.
Do you put liquid bt in a spray bottle too?
You can. The insecticide label probably has the amount you have to put in a gallon. You would just need to do some math to adjust that to the size of your spray bottle.
@@FamilyPlotGarden thanks. I read the label and figured out that I should add about an ounce per gallon of water.
Is it harmful to humans when eaten from vegetables of treated plant?
Yes, and companies are paying highly to hide this fact. Just google BT and mice organ damage
Hornworm can strip a tomato plant in one night. Waiting 2 days for BT to work will result in a killed tomato plant.
Need something a LOT faster.
How many ounces do you put to a 39 oz spray bottle
That information is on the label of the product you purchased. It comes in many concentrations so i can't give you a specific number.
How much Monterey Bt when wixing a 32oz spray bottle
To figure out how much to use read the label on the side of the BT bottle. Different manufacturers have different concentrations so there is no one set amount to use.
4tsp per gallon so 1tsp per 32oz of water

Can you spray BT into your mouth
Thank you! Just found the culprit under a rose leaf! Yuck!
It works for aphids.
Banned in the UK for small gardeners because its linked to Gastrointestinal diseases in humans and bio microbial disturbance in the eco food chain.
Don't apply directly to plants..... as he sprays the plants
Pay attention 😆
