Use Cockroach Traps to monitor for their presence. Place traps in several locations, and move them frequently.
Place them where they will enter while foraging. Good locations are behind the stove or refrigerator, and in a cabinet containing food.
Reduce food, water, and anyplace they can hide. Place all food in sealed containers; repair leaks; seal up cracks.
Use boric acid in cracks you cannot seal. Or place boric acid where you know they will walk through it.
Boric acid clings to cockroaches, and they will ingest it as they clean themselves.
Use Boric Acid and sugar as bait.
The idea plan calls for a careful survey of the place, the mapping of all breeding places and identification of the species.
This is necessary in order to determine the kinds of mosquitoes present and their breeding habits.
Control consists essentially of destroying the larvae and their breeding places.
Tin cans and all objects that may hold water are eliminted and necessary water receptacles, as rain barrels and cistern are treated periodically.
Drainage provides permanent control and is used to eliminate small pools,swamp and marshy areas; ditches and creeks are cleaned up so that the water flows evenly and does not back up.
All buildings should be screened to prevent entry of the insects. Where there are no screens, sleeping nets should be used.
Mosquito surveys are mde by the use of light traps, animal traps, counting specimens in houses and catching in the field. Man is sometimes used as bait for those species that prefer him. The trp is large and the entering mosquitoes are unable to escape; the man is protected by netting within the trap.
Several kinds of small fish, particularly Fundulus and Gambusia, are useful in controlling mosquitoes and are often introduce into ponds and other breeding places. They are valuable for use in receptacles where water is stored, such as rain barrels, pails, water tanks etc.
No matter what chemical is chosen for the job, effective control depends on searching out ll there hiding plces. The various refuges are upholstery of chaire and couches, loose wallpaper, picture frames, openings of water pipes should be examined.
Even when the bugs themselves cannot be found, spots of faecal material reveal there hiding places.
Spray of 1% malathion, 1% fenchlorphos, 0.5% DDVP and 0.5% synergized pyrethrins have given good results.
Hand sprayer usually is dequate and spraying should be done early in the day so the insecticide can dry before the room is used for sleeping.
Pyrethrum treatments, because of there limited residual action, should be made several times at weekly intervals.
In addition to sprays, insectcide dusts may be useful for control of bed bugs.
Recently, a dust based n diatmaceous earth and synergized pyrethrins became available for treatment of baseboards, molding cracks, bedsteads and both sides of mattress for bed bug control.
