Spinosad - does it expire?

Charlotte, NC(Zone 7b)

If anyone has Spinosad could you please see if it has an expiration date?

Last year I had a problem with vine borers, and I understand Spinosad will kill these pests. However, I don't want to invest in a large container of Spinosad only to find out that it expires in a year or less!

Thanks for your help.

I'm looking at my bottle of "ferti-lome Borer, Bagworm, Tent Caterpillar & Leafminer Spray" (5% Spinosad) and there is a lot number but no expiration date anywhere I can see. A google search didn't turn up anything either - the only matches for "spinosad expiration" concerned the expiration of patents and the like.

I wouldn't necessarily take that to mean it doesn't expire, just that they don't know or are not required to tell us. OTOH, many expiration dates are based on less-than-optimal storage conditions.

And I swear, some expiration dates are just there to get you to buy more. If got a bottle of potassium citrate with an expiration on it. Short of inoculating it with some weird life form and adding moisture, that stuff just doesn't go bad.

I see bottles of distilled water with expiration dates on them. Unless the plastic leaches chemicals into the water, how does it go bad.

I decided it would be helpful if I gave a link to the product I'm considering buying:

I don't want to purchase such a large bottle if it will expire in less than a year. I didn't realize that another product called mycorrhizae expired within a short period of time until I purchased some and read the label.

Bear with me, please. I'm not used to using pest deterrents in my garden, but the sow bugs and slugs numbers are really terrible this year, and I'm concernd the SVBs will arrive in droves later this summer.

I have Sluggo Plus on order, it's due here next week.

I have the Sluggo Plus. I will check for an expiration.

I just laid some out the other day and of course it rained very hard the last three nights so I am not sure if it is still going to be effective. The slugs have come out in numbers and have been eating my lettuce. I finally have a nice large crop of lettuce that is doing really well and the slugs are tearing it apart. So frustrating!! I put some shallow dishes out there with beer and the centipedes really love to commit suicide into it. I had about 25 of them in the one dish yesterday morning. I think they are centipedes anyway. They resemble the general shape of a centipede but are not flat and their legs are not as long but they still have a lot of them.

I have some Capt. Jack's Dead Bug Brew and no expiration on that is listed anywhere. Do you know if that Monterey is ready to use or is a concentrate? It it's concentrate, I think that's a great price.

bariolio -

Do you know if that Monterey is ready to use or is a concentrate?

from what I can tell, it's a concentrate.

Spinosad will only give you limited control of SVBs, but it is better than nothing. You mentioned Sluggo Plus, does anyone know if Sluggo Plus really works on pill bugs/sow bugs? They are eating everything in the garden. I have regular Sluggo for snails (limited success) but haven't bought the plus because of the extra cost. I buy spinosad, ultra concentrated, from a local greenhouse supply. I will check for an expiration date, but not sure that would help since mine is powdered.
According to their product label you use 2 ounces per gallon, same as the Greenlight brand of spray with spinosad.

Calalily - it has been my experience that Sluggo Plus will kill sow bugs. I just invested in a 5lb container. Expensive, yes! A little goes a long way.

The sluggish plus seems to work very well for me. I haven't noticed the mass quantities of pill bugs and slugs since use.

Spell check. SLUGGO plus :)

Thanks, I will try the Sluggo Plus. They are eating everything. I keep hoping the lizards and frogs that live in the garden will eat them, but they must taste bad because nothing eats them.
I use regular Sluggo in the garden and get so-so results with snails. We only have two kinds, a soft shell pointy kind and a little hard shelled round snail. The snails even climb up in our citrus trees. I remember reading that snails and pill bugs love organic gardens because of the lack of chemicals and it seems to be true.

One would hope that those critters that eat snails and pill bugs would love organic gardens, too, so as to have a wonderful chemical-free feast. Good luck!

I do have lots of beneficials: black ground beetles, tiger beetles, soldier beetles, lady bugs and I saw lace wings yesterday. Guess I have too many snails for them to eat! I hate going out to pick a nice ripe tomato and the top is eaten out by rolly pollies and there are millions of them under anything that touches the ground.
The tiger beetles are neat to see at night, they run around in circles when you shine a light on them. Spider eyes show up beautiful blue in LED light. I love going into the garden at night.

A little does go a long way. And, I have found it to still be fairly potent after a rain...I usually sprinkle a perimeter and then drop a few pellets onto the surface in my containers. In this case, I'd sprinkle some onto my raised bed...

Why don't you contact the company that produces the spinosad you're interested in? Or contact the manufacturer of Captain Jack's Deadbug, which you can get in inexpensive spray bottles or concentrate.
