wanting to make a homemade bug repellent

I need something that will protect my buds from caterpillers, aphids and grasshoppers(grasshoppers arent around now but they are in the late spring and summer and they are annoying and ugly!) I was thinking of using garlic or tobacco tea and spray it on my buds but i wanted to know if they were safe on the flowers and wont make them smell weird or something.

Tell me what you all think. Thanks.

You want some BT:

You might find some in lowes organic section, most nurseries have it... It is organic and harmless and wont mess with your smoke...
You can also use 10% Sevin dust. It has been around a long time and is one of the dafer pesticides.
If you get Grasshoppers you are basically screwed if there are very many.
You can use Garlic. I wouldnt use tobacco tea, that is poisonous to humans. Some people sprinkle red pepper on plants (Cayenne)
If the caterpillars are big just squish em.
Good luck.

lots of good organic solutions here:

kind of broke atm so im kind of looking for a home remedy. would the garlic do what i need? can planting some in with the plants help too? im kinda leaning on garlic because it sounds safe.

I dont think Garlic will do anything for the worms.. you could try it and sprinkle some cayenn on there dry. You can get some at dollar store for $1,
Do a google and search for homemade insecticidal soap too. The BT can be high but it goes a long way and I promise they will die in agony.

Soapy water mate nuff said works for the hippies worked for me too.

moth balls are always good i take it ur growing guerilla

sort of guerilla but its in my backyard i just have to keep it out of view from people walking on the trail that goes past there. My makeshift greenhouse keeps the aphids off them and will keep the ghoppers from getting at it in the spring and summer but those damn ugly little caterpillers still get in somehow.
