CONTROL 
Apply a residual spray to control brown dog ticks and 
soft ticks in the home. Dusts can be used. but they are 
harder to apply and are unsightly in exposed places. 
Household spray formulations come in_ different 
strengths and are ready to use when purchased. 
Use a spray that contains either 5 percent of DDT, 
2 percent of malathion or 2 percent of chlordane, 1 per- 
cent of lindane, or a combination of DDT and chlordane 
or activated pyrethrum. 
Apply with a hand sprayer or household sprayer. 
Apply the spray thoroughly to baseboards, around door 
and window mouldings, behind pictures, under furniture, 
around the edges of rugs, on curtains and draperies. and 
in all cracks. 
For several weeks the residue left by the spray kills ticks 
that come in contact with it. One application is usually 
sufficient. but if ticks are numerous after the second or 
third week, repeat the treatment. 
Precautions 
Handle insecticides with care. Most of them are likely 
to poison people and animals if they are handled 
carelessly. 
Store insecticides where children, pets, and livestock 
cannot reach them. Label containers plainly. 
Avoid inhaling sprays and dusts. and do not expose the 
skin to them more than is necessary. If you spill the 
material on skin or clothing. or get wet with the spray. 
change clothing and bathe immediately. 
Do not apply these insecticides to crops, grazing areas. 
or livestock. 
To avoid killing fish when applying insecticides near 
streams. lakes, or ponds, do not let excessive amounts 
get in the water. Be especially careful when using dieldrin 
or toxaphene near fish-bearing waters. 
Do not contaminate water supplies, such as wells and 
cisterns.
