Brand Caterpillar Killer II Concentrate Spray, 16 fl oz | Kills Caterpillars, Gypsy Moth Larvae, Worms & Cabbage Loopers, Organic Pest Control Spray, Outdoor Use in Plants & Gardens

This product really works! Tobacco Budworms were eating all my petunias and after spraying with this solution twice, within 5 days I had full blossoms returning and no signs of any further damage.

Squash vine borers ate up all but two of my squash. I tried injecting this directly in the stems, and to my surprise it seems to have worked on my last two plants, fingers crossed.

If you want an organic way to prevent caterpillars from eating leaves on your trees, especially fruit trees & ornamentals, this is a great way to go. Totally organic bacterial prevention that makes the caterpillars ill when they start to eat. I can spray this all over my weeping cherry tree, peach tree, and any oak & maple branches I can reach with my hand pump sprayer, and the tent caterpillars & inchworms that have plagued those trees for the past couple years are very effectively eliminated. The only drawback is that it must be reapplied about weekly or after heavy rains. As long as you're only dealing with a few trees, this is manageable. And it's really nice to spray this without worrying about the kids & pets & beneficial insects & birds getting harmed. I've tried non-organic stuff in the past and it absolutely kills the caterpillars more quickly and often with a single application, but I like that I can use the BT and still let the kids & pets walk around the yard without worry. I'm using it in a 2-gallon hand-pump sprayer and have applied it once every 1-2 weeks and can say it has very effectively prevented caterpillars from damaging my trees, while neighboring trees have leaves that look like swiss cheese.

UPDATE for 2020.... It's official. Not a SINGLE corn ear worm this year. Follow my review below and you'll never lose corn to that fish bait again! This stuff is dynamite! --------------------------------------------- If you have a problem with corn ear worms I hope you'll stick with this piece. It's my Christmas present to your garden. I have been planting corn in the same location for nearly 40 years so I know most of the tricks nature is liable to throw. This year I didn't have the perfect storm early in the season to leave the corn patch a tinkertoy mess. And we got enough rain and at the right time for a change so it was shaping up to be a great corn year. Corn, btw, gives the most ROI in growing pleasure. You really get a lot of bang for that little kernel. I LOVE just watching the stuff grow. Watching the honeybees at work etc. Love it! Anyway I always grow Golden Queen...which after years of experimentation works the best for me. This year I planted 5 rows, 60ft long. It's a back yard garden. Last year I bought Safer Brand 5163 Caterpillar Killer II Concentrate as an afterthought and sprayed at the corn a time or two and as usual 1/3 of the crop got gnawed. When shucking time comes normally on most of the ears I have to lop off the top....sometimes all the way to the middle. I live in corn worm heaven. Always have. We get very few perfect ears, and it's always a surprise when the queen ear of golden queen pops up un-gnawed. So I put most of the bottle into the fridge unused. Right next to the ketchup. Eyed that bottle all winter! This year I decided to go all out so at the first sign of silk I started spraying every other day up until about a week before harvest when I just got tired of doing it. Ha. Keep in mind that I was using the bottle I had held over a year in the refrigerator. I also sprayed my 32 tomato plants every other day. It may have knocked the horn worms back but not completely. In my case it probably didn't hurt but I eventually had to nuke them with a more lethal product. Put it that way. To be fair the jury is still out on tomatoes here. Back to the corn.... Last week I shucked out 162 ears on the first pick. Folks! I NEVER HAD SO MUCH FUN SHUCKING CORN! Out of that 162 I had to nip the tippy top out of 7 or 8 ears tops...and that looked to be from weevil chewing and not much of that. But out of 162 ears NOT ONE SINGLE EAR WORM!! Not a one! No sign. No worm. No nothing but ears of corn that looked like they came straight off the show room floor! Bam zoom zowie! Real state fair winners! Yesterday we did the second pick and out of that 50 not a single worm. It's unnatural! Normally the second pick is horrible! This time....only great pristine non chewed perfect ears! Bottom line I'd say that in my nearly 40 years I'll never top this corn harvest. BTW, I tried BT 30 years ago in powder form. Then I couldn't find it again for another 25. I always remembered that stuff and that's what prompted me to look for it again last year. Now it's all over the place. Safer Brand 5163 Caterpillar Killer II Concentrate really is concentrated. Even after all that spraying I still have some left over. Judging by my experience you could spray at least 600ft/row with two gallons made with two tablespoons. I may have practiced overkill, doing it every other day....but it WORKED. Why take chances? Spray at the first sign of silk... Even spray where you think the second ear may form if your corn puts on more than one ear. Do it every other day. And spray FROM THE TOP, making sure that some of the spray juice gets inside the ear. Do that and you will also have PERFECT corn and I don't care if you live in Ear Worm County. Spray nearly up to harvest. Get mean with that greedy fish bait. Do that and when you harvest you'll be thankin' me!

I used this on Hydrangea bushes to kill Leaf Tier insects. I opened the leaves, then sprayed the entire bush, & they did not come back.

This stuff really works on scarlet lady beetles(in the caterpillar stage) and squash vine borers. Just have to be careful to stop using it when the blossoms start. I don’t want to kill the pollinators.

This product will kill caterpillars when used correctly. But therein lies the problem. Because it only kills them when they eat the leaves or flowers, and because it does not last long on the plant, you have to repeat use regularly. For me, that means once a week to keep the critters in check. And using a pump spray for all of my geraniums takes way too long to do it once a week all summer long. So if you have the time to reapply on a regular basis, and you want a safe spray that will only kill the buggers eating your plants, then this is the product for you. But if you want something long lasting that doesn't require reapplication regularly, look elsewhere.
