House Crickets .. il:
'~. :!
The light brown or tan house crickets Fire 3/4 tol.:lB
in length when mature. They are common louse pqets Ina .,
Europe, but in this country they also thrive out Of T.o 'ors:.:!
They are most troublesome in houses located near city dutp3Th4
or other areas being filled in with refuse., In the hollow ,8,.:K
spaces within such dumps the crickets find manv places to 'A
hide and multiply, and the refuse itself furnishes sufflct..
food for their development. The house crickets swarm 'from T'I
dumps at about dusk, and fly or erawli to houses. -They a":|
crawl to houses in multitudes and eain access to the inteir
through small openings in walls and roofs or throu* dilnoVi!W
and doors not perfectly screened.. Sonfetimes they. can be-.'....
swept up by the pailful. This migrati-on from' durpq -.to '
houses usually occurs -during July to September.
..~~~... 5;.N :
In large modern housing projects, in a mildL climate, .
the house cricket may become a year-aronnd nuisance except,: *.1.,,'
in midwinter, and may overwinter in all stages of growth.-.j
Generally crickets make their annParance in .uch buildinE, ...|
during April and Mayv They seek a good harborage beneath '
the buildings in the unexcavated areas through which the .
heating pipes pass, and migrate thence to apartments alo ..r
the plumbing or conduits for various installations. .

Liberal dustingof floors along the baseboards with
fresh nyrethrum powder, sodium fluosilica.te, or sodium
fluoride, or blowing these powders with a hand bellows into
cracks and other hiding places will kill crickets. Pyrethrum
powder'is not now (lqh5) available, but sodium fluosilicste
and sodium fluoride can be obtained. They are poisons and
must be used with caution.


*^ '': .. When houses are overrun with crickets, a Doisoned bait
Smy', has Droved an effective control. A good bait can be made
;'"! by mixing 2 I/2 pounds of bran, 10 teaspoonfuls of sodium
..".. fluoride or sodium fluosilicate, 4/5 cuD of molasses, and
M.:' 1 quart of water. Small lots of this bait should be
.] : scattered in various parts of the house, including the base-
.~:m. ent, where crickets are known to crawl. Being poisonous,
V^'L *the bait should not be exposed where children or pets can
.:."J i ii" ...
". ,eat it.

: .Out of doors.-When crickets are numerous about the
:. house aMd are constantly gaining entrance, killing th'n out
..o .. f doors is the best method of attack. The poisoned brit
S.,.... can be used successfully about yards and house foundations,
''.":.- .. and over dumps. If the crickets are coming from a dump,
.:' the town or city authorities should be held responsible for
2: treating the duin heavily with the bait several times a week
until the cricket migrations end. The poison bait should
