it was probably the larva of the gnats eating the leaves

I have used and seen how coffee grounds under and around all your grape plants should keep them away . Boric acid also works well to rid oneself of ants . Spread across their path and they bring back to the nest . I need to learn how to rid myself of normal sized flies with some gold on them from eating my ripening red seedless grapes

kimmsr, Disagree with you, simply based on experience. I used to have lots of grubs in my very moist compost before using BT. Rarely see a grub of any kind anymore, using the same methods/materials with the addition of BT. http://www.nysaes.cornell.edu/ent/biocontrol/pathogens/bacteria.html States: Primary hosts: caterpillars; some BEETLE and fly larvae. Also states: "Over 90 species of naturally occurring, insect-specific (entomopathogenic) bacteria have been isolated from insects, plants, and the soil, but only a few have been studied intensively". So I give credit to BT. I put some good soil in my new compost piles, which has had applications of all commercial BT strains, so I can't say which one (if any) are at work against grubs. Doesn't matter to me. So I give credit to BT, et al. - and don't have names for the other 86 or so insect-specific (entomopathogenic) bacteria spoken of, OR other such non-specific bacteria that may not have been identified yet. http://ohioline.osu.edu/hyg-fact/2000/2500.html : 'Grubs' is a 'generic' term, used for larvae of a large group of beetles called SCARABS. The most important species are: Japanese beetle, Popillia japonica Newman; May or June beetles, Phyllophaga spp.; northern and southern masked chafers, Cyclocephala spp.; and black turfgrass ataenius, Ataenius spretulus (Haldeman). Other, more localized, white grub pests are: European chafer, Rhizotrogus majalis (Razoumowsky); the Asiatic garden beetle, Maladera castanea (Arrow); and the green June beetle, Cotinis nitida (Linnaeus). Option 4: Biological Control - Milky Diseases - Several strains of the bacterium, Bacillus popilliae (bacterium is extracted from Japanese beetle grubs and is most active against this species), have been found that attack white grubs...Unfortunately, recent studies in Kentucky and Ohio indicate that the currently available products have NOT PERFORMED WELL IN OUR SOILS. (caps are mine). Goes on to say that parasitic nematodes are a up to 80% effective, but "...do not appear to be effective from one season to the next". So you can take exception with me if you want to - your opinion is just as valid as mine - but now let's hear from YOU about your EXPERIENCE with grubs... Robert

Fruit flies have a distinctive, zip and float ziggy flight pattern, unlike other flies with stronger, long lines of flight. Will these flies actually ignore a ripe, cut banana?
