Bacillus popilliae (also known as milky spore disease) is effective against larva of Japanese beetles. Some brands claim control of oriental beetles, Rose chafers and some May and June beetles. Some commercial products are Doom, Japidemic and Grub Attack. It takes one or more years to completely control beetles.

Bacillus thuringiensis (Bt) is a bacteria which attacks caterpillars and various other insects depending on the variety. Dipel, Thuricide, Bactur, Mosquito Attack are some commercial names associated with Bt; be sure and read the label for pest effectiveness. It disrupts the insect's digestive system so they starve. It is a very safe remedy.:

var. berliner/kurstake is effective against leaf-eating insect larvae such as loopers, hornworms, corn earworms, gypsy moth caterpillars, oakworms, meal & flour moth worms, diamondback moth caterpillars, fruitworms, leaf folders and most species of leaf-eating moth larvae and butterflies.

var. San Diego tenebrionis is effective against Colorado potato beetles and elm leaf beetle.

var. israeliensis is effective against mosquito larvae and black fly larvae. It can be applied to water breeding sources for mosquitos.

Nosema locustae is a single-cell protozoan which can infect and control grasshoppers of the Malanoplus family, locusts and mole, mormon and black field crickets. Takes up to a year to develop good control. Nolo and Grasshopper Attack are two of several commercial products available.


Caterpillars, aphids, mole crickets and whiteflies are some of the insects attacked by fungus.

Aschersonia (red and brown) attacks whiteflies and can completely destroy a population.


Steinernema and Neoaplectana carpocapsae prey on termites and the larvae and grubs of various beetles, weevils, armyworms, cutworms, chafers, webworms, borers, maggots, fleas and fungas gnats. This nematode enter their prey through body openings and kill their host within 2 days. The nematodes continue to produce and seek new prey. Check the label on Scanmask, Biosafe, Bio-Logis and Grub-Eater commercial products for specific pests that they are effective against.

Heterohabditis bacteriophora is similar to S. carpocapsae but it can enter it's prey through it's body walls as well as through body openings.
