Hi this is Yolanda Vanveen and in this segment we're going to talk about how to control Japanese beetle grubs. Now the Japanese beetle is originally from Japan but it's found all over the world now. And it does lots of damage to plants. It just eats away the leaves and there's only a few ways that you can actually control the population. It's much easier to control the particular plants then trying to control a whole area. But if you fight it a little bit at a time, you can make headway and control the grub and the beetle because the grub is actually a little sea shaped worm that looks and grows under the ground and it'll eat away lawns just like the crane fly larvae will. So sometimes you can confuse the one for the other, but they do lots of damage and so if you get them when they first start, a lot of times you can get rid of them naturally, but sometimes if they control a whole area, sometimes you have to go and get some kinds of pyrethrins which are a chemical that will kill all the bugs in the area which would be a very last resort. But we're having to do that in some areas where they're just taking over and its unfortunate because pyrethrin is really a toxic chemical, it's just found in chrysanthemums but they're finding that women that wash their animals in a flea bath that has pyrethrin in the when their pregnant, there is twice as likely of a chance to have children with autism. So it's a chemical I really don't like to use at all. But if you do have Japanese beetle grubs, you can protect your plants in a lot of ways. Just by hosing them off with a hose. So if there's any grubs in them, a lot of times you can wash them out. So from the underside of the leaves too, just wash your plants very regularly, all the leaves so even if they're on a drip system, make sure you water them by hand. A lot of times by putting an oil, neem oil is an organic oil that they're finding that is not so dangerous, it's still an oil you don't want to use for children under two, which makes me wonder it can't be that naturally OK to use if they still don't want to use it on young, young children, but still, it's a little bit safer than pyretrhin and by spraying neem oil on any of the bugs, that works really well too. But my theory is, if neem oil works, so does eucalyptus oil, lavender oil, vegetable oil, olive oil, any types of oils work really well with most bugs. So I just try to spray down the trees and if you see any Japanese beetles, just spray them with some oil and that a lot of times it doesn't always kill them though, because some of them can be really big and so there's really not a lot that you can do. But make sure that if you do have problems with them, especially near your home, that you make sure that there's no access to your house from the outside and close up any little holes that all and that way you can control the bugs inside and outside of the house.
