Birth Control for Fleas. Parasitic nematodes attack pupal and larval
stages of fleas (in many lawns, not indoors or on pets) and other
soil-dwelling pests, including insects which spend a part of their
life cycle in the soil or on plant roots. These nematodes are not
the same as those which attack plants. Effective against cutworms,
armyworms, cucumber and Colorado beetle larvae, bill bugs, fungus
gnats, black vine weevils, Japanese and June beetle grubs, termites
and sod webworms. Growers have had success against cabbage root
maggot, walnut husk fly, onion maggot, artichoke plume moth and
raspberry cane borer and numerous other pests.
Note: parasitic nematodes are not used to control pest nematodes.
The parasitic nematodes enter their prey through body openings and
release bacteria that kill their host within 48 hours as the
nematodes continue to reproduce. The Heterohabditis bacteriophora is
similar to Steinernema carpocapsae except that it is a better option
for warmer soil conditions. This treatment takes effect faster for
Japanese beetles than Milky Spore, but it requires annual
re-application. Mix with water and spray on the soil anytime pest
insects are present and soil temperatures are above 50°F, depending
upon type of nematode purchased. Complete directions are included.
Short shelf life; plan to use within 1-2 weeks of arrival.

Continual use of the dusts, sprays and vacuuming mentioned
in previous steps will provide a form of birth control for fleas. I suggest dusting
once per month during flea season and spraying as often as needed. Just use only
pure natural dusts I have discussed.
