On Lettuce: 
Cutworms: Several different kinds of cutworms attack lettuce. The 
majority of them can be controlled by the use of a poison bait especially 
formulated for cutworms. 
Grasshoppers: For grasshoppers attacking lettuce, use' the standard 
grasshopper poison bran bait. See us for formula. 
On Melons: 
The insects found attacking cantaloupes are also enemies of melons and 
the same methods and poisons should be used against them. 
On Onions: 
Thrips: This is the worst pest of onions. It is a very small, louse-like 
insect, light yelloAvish in color, that feeds down between the leaves causing 
them to turn white. It is difficult to control successfully, but very good 
results can be obtained by fumigating with Calcium Cyanide or Nico-Dust 
under long hoods that are dragged over the rows. 
On Peas: 
Pea Aphis: A large green plant louse. Use a contact insecticide when 
they first appear on the plants, repeating every ten days until controlled 
or all peas have been harvested. 
On Potatoes: 
Colorado Potato Beetle: A large beetle, yellow with black stripes. The 
young are orange yellow. Use 2 pounds Lead Arsenate in 50 gallons of 
water. 
On Spinach: 
Flea Beetles: These are small shiny black beetles that fly rapidly when 
disturbed. Because of the danger of poisoning, the arsenicals cannot be 
used, and it is necessary to treat with a very strong contact insecticide 
such as the Nicotine or Pyrethrum compounds. 
COMMON INSECTS IN THE FLOWER 
GARDEN 
ANTS: The laige red Harvester Ant will attack almost every living thing 
growing near to its nest, besides being troublesome because of its bite and 
sting. Calcium Qyanide is the best poison to use in the control of this 
pest. Use four to five tablespoonsful per nest, digging a hole in the 
center of the mound 16 to 18 inches deep and placing the Cyanide in the 
bottom and covering over tightly with soil, as the gas is lighter than air. 
APHIDS OR PLANT LICE: There are many kinds of aphids that 
injure flowers in the garden. They may be reddish, green or black, and be 
with or without wings. Roses, Stock, and Sweet Peas are especially sub¬ 
ject to attack. Control with a, Nicotine or Pyrethrum Spray or Dust. 
CUTWORMS: They attack many young plants in the Spring and early 
Summer. If the plant is cut off at the surface of the ground or the roots 
eaten, put out the cutworm bait, scattering it thinly along the rows affected. 
There are some cutworms, however, that climb the plants at night, eating 
the leaves. For this insect spray or dust with Lead Arsenate, Calcium Ar¬ 
senate, Dutox or Fluoeide. 
LACEWING BUG: This is an especial pest of Hollyhocks. It works on 
the under sides of the leaves, turning them a brown or yellow color. Spray 
with a. Nicotine or Pyrethrum Compound, taking pains to get the poison 
on the under side of the leaves. 
THRIPS: This insect bothers roses, particularly in the Spring. Spray 
thoroughly with a Nicotine or Pyrethrum Spray. 
GRASSHOPPERS: These are especially injurious to Zinnias in late 
Summer and Fall. Use the poison bran bait. 
COMMON INSECTS TN THE HOUSE 
ANTS: For the small black or red ant that infests the house and gets 
into the refrigerator, sink, etc., bait by setting out Antrol. This has proved 
100% effective where tried and is the cleanest and simplest of methods. 
COCKROACHES: Spread Sodium Fluoride or Sodium Fluosilicate 
about where the roaches are in the habit of traveling. This will rid the 
house of them in less than a week. 
TERMITES: For information on control call us or write to the State 
Entomologist, the University of Arizona or the County Agricultural Agent.
