    What do you apply nematodes with? A hose end sprayer? Any filter to take out?

    I'll be doing this for the first time soon so I just want to make sure everything goes smoothly.

    Thank you!!

    I listen to radio show weekly and our guy says use hose end sprayer. They must be refrigerated in the store and your home until you use them. I don't know about filter.

    i have used a 1 gallon sprayer that used for non pesticide applications but a miracle grow hose end sprayer works fine. just make sure the container is cleaned out. i purchase my nematodes from a company called gardens live and they supply pretty thourogh instructions.

    I applied them once for a customer and used the hose end sprayer...worked fine.

    I think its a joke but my sprayer didnt clog or anything.

    I have been using the beneficial nematodes for several years. I have found that a low pressure hose end is best. As for the filter, I would remove it. Although these dudes are microscopic, some may actually be large enough to pose a problem. Be certain that the sprayer has had nothing harmful in it as even a slight chemical residual can kill your todes.
    Purchase your todes direct or from a reputable organic supplier, they have a shelf life of about 6-8 weeks and must be refrigerated upon purchasing.
    Create a stock solution for the todes. Spray over a premoistened lawn in the evening. They will survive wherever vegetation survives.
    Add a few tablespoons of horticultural molasses to act as a carbohydrate source, it is much like giving a Hershey bar to a 3 year old. Don't have molasses? Use a flat coke, (not diet), works great too.
    Remember they do not care who purchased them and they travel on, they are not going to turn around once they get to the fence because they belong to you. I apply them 3X year and always purchase the kind that are sold on a sponge, not in a vermiculite looking medium.
    After 5 years at my current address, I have NO ants, NO grubs, NO ticks, my dog has NO fleas (and I do not use any chems on him either) And Yes I have lots of earthworms as well as the desirable microbial activity necessary to maintain the balance of the soil.

    Lawnchick -Sounds like you are very knowledgeable about the todes. How long do you think I should wait to apply if I have used Merit in the past? We are having some grub problems now and are about to contract with a pest guy to spray for them but I would prefer to go the green route. Duh I guess if the grubs are alive the todes will be fine. I have used Arbico in the past (out of Tucson) but their Todes come in a powder form and I have had mixed results. Where do you get yours? Thanks for the info and welcome to lawnsite.

    Hopefully it has been a while since your last chemical application (6 wks), and if you use plenty of compost, the microbes should have done a pretty good job breaking it down. As for the sprayer, I would consider purchasing another one. The cheap ones have always worked fine for me. If that is not an option, rinse your existing sprayer with vinegar, no need to go after the 20% used as an herbicide, table vinegar will be perfect. Contact Hydro-Gardens, (http://www.hydro-gardens.com/guardian_lawn_patrol_nematodes.htm) for a fresh supply. They will overnight them in cold packs. The Guardian and Lawn Patrol varieties work best for me in here in South Texas for the insects we battle. Hydro-Gardens can reccommend a flavor for your parts. Thanks for the welcome!
