Dusting woodland litter to till lone star ticks. 

 The applicator is a rotary hand duster. 



To kill American dog ticks and black-legged ticks, spray 

 or dust a strip 20 to 30 feet wide on each side of roads 

 and paths. To kill other species of ticks, treat the entire 

 infested area. ( If a survey shows that lone star ticks are 

 concentrated in thickets, treat only those places.) 



On lawns and grounds up to an acre or two. or along 

 roads and paths, apply the insecticide with a 2- or 3-gallon 

 hand-pressure sprayer or a plunger- or rotary-type hand 

 duster. If the area is large or the roads or paths extend 

 over long distances, use a power sprayer or power duster. 



Aircraft can be used to treat some large areas of general 

 infestation. Large area treatments may prove hazardous 

 to wildlife. Do not treat unless necessary to protect 

 humans from ticks and the diseases they carry. 



Using Repellents 



The mosquito repellents deet (diethvltoluamide) . di- 

 methyl phthalate. and ethvlhexanediol. applied as clothing 

 impregnants. will provide some protection against wood 

 ticks. If you wear socks, shirt, and trousers impregnated 

 with one of these materials, you can expect about 75- 

 percent protection from ticks. 



Better protection can be obtained with another repellent, 

 [ndalone, but it is not widely available. 



I se the selected repellent in a solution or an emulsion. 

 A 5-percent solution or emulsion will provide an effective 

 deposit on ordinary cotton khaki, denim, or light wool 

 clothing. About 3 pints of solution or emulsion will 

 impregnate an outfit of socks, shirt, and trousers. 



^ ou can make a 5-percent solution by mixing a repel- 

 lent with acetone or a drv-cleaning solvent at the rate of 

 1 ounce of repellent to 1 pint of acetone or solvent. 



You can make a 5-percent emulsion by mixing 1 ounce 

 of repellent with 1 pint of water and 2 ounces of an 



Spraying vegetation to kill American dog ticks. 

 The applicator is a compressed-air sprayer. 



emulsifier such as Tween 80 or Triton \-100 or 1 ounce 

 of laundry soap. 



Dissolve the emulsifier or soap in the water and add the 

 repellent slowly while stirring the mixture vigorously. 

 (Synthetic household detergents are not suitable for mak- 

 ing emulsions but most laundrv soaps are satisfactory.) 



Dip the clothing into the repellent mixture or pour the 

 mixture over the clothing. Then wring out the clothing 

 by hand. Let it dry thoroughly before wearing it. The 

 repellent will remain effective for about a week unless the 

 clothing gets wet. Wash and re-treat clothing at weekly 

 intervals. 



Do not treat ravon and nylon fabrics with repellent 

 solutions or emulsions. Nylon is nonabsorbent and will 

 not retain enough repellent to be effective. Some types of 

 rayon may be damaged by the repellents. 



Ticks in Homes 



Although wood ticks seldom occur in homes in numbers 

 that make control measures necessary, other ticks, chiefly 

 the brown dog tick (Rhipicephalus sanguineus), will infest 

 homes and other buildings if dogs are present. 



The brown dog tick passes through the same stages as 

 the wood ticks. In homes, the eggs and engorged ticks 

 may be found in cracks, behind curtains, and under 

 furniture or rugs. The tick will survive the winter out of 

 doors in the most southerly States, but in most of the 

 country it survives only in heated buildings. It seldom 

 bites people. 



Soft ticks belonging to the genus Ornilhodoros some- 

 times occur in homes in the Western and Southwestern 

 States. Thev are extremely painful biters and several 

 species transmit the germs of relapsing fever.
