| Hi all, have a quick question. So ive been using Milorganite to try and build up my soil for the last two years and it has been fantastic, i havent had any issues with it. Now i seem to have a few grubs and yellow/brown patches. Not due to water stress or lack of fertilizer. Im thinking i need to put down some grub granules. Now will this kill all the beneficial bugs that ive tried to build up over the last two years? Any advice on whether or not i should put it down? im in central Nj, grass is a northern mix mainly KBG/fescues. |

| Another way to get information about organic pest control is to ask the question, "How do you organic folks deal with [name your favorite pest]?" For grub worms we use a product called Beneficial Nematodes. BN bring a bacterial disease to grubs and kill them just about immediately. You likely already have a few of the BN in your soil - just not enough to handle the influx of grubs. The disease is harmless to mammals, birds, fish, etc. The way you use them is to thoroughly soak the soil first. BN need a film of water of move around in. Then apply the BN with a hose end sprayer. Then I would water again to wash them off the grass and down into the soil. I get the BN from this place. Use them right away or store them for up to 2 weeks in the fridge. |

| Dchall, so an update. I purchased the BTs from your suggested retailer and put them down yesterday evening. Very easy process actually; im hoping for good results. Now it was wet when i put them down and cloudy and i watered them in as well. My question is the weather looks like it might warm up again going from 80-90 in the next week, should i keep the soil moist for a couple days or do you think they have already gotten to where they need to go? |

| If you normally would water again in 7 days, you might do it in 5 days this one time. That will give any baby nematodes a chance to launch on their own careers of killing pests. As I understand it, the nematodes have something like 270,000 babies, so some of them should get out and make a name for themselves. |
