Guide

Insect Control

BY THThOMEOWNER

Much has been said about the effects of pesticides, par-
ticularly insecticides, on the health and well-being of
the American people. The homeowner, however, is also
aware that he is constantly faced with a horde of in-
sects, intent upon destroying his property or making
his life uncomfortable. Occasionally he can avoid or
reduce the destruction wrought by some pests without
using an insecticide, but to control most insects, he
must rely on an insecticide. This will provide the satis-
factory control that he demands.

By careful use of insecticides, the homeowner can
enjoy reasonable freedom from insects without endan-
gering either himself, his family, or his pets. He must
recognize, however, that insecticides are designed to
destroy one group of animals — insects — and can be
harmful to other animals, including man himself, if
used with disregard of normal safety precautions. It is
up to each insecticide user to handle, apply, and store
insecticides safely to reap their benefits without suffer-
ing from their dangers. For further information on
safe use of pesticides Circular 906 is available from the
College of Agriculture at Urbana.

The suggestions in this publication list certain in-
secticides to control insect pests of food, fabrics, struc-
tures, man and animals, lawns, shrubs, trees, flowers,
and vegetables. We have tried to suggest only the
safest materials that the homeowner needs. Many
people prefer to employ the services of a professional
exterminator or custom applicator rather than to be-
come involved with selection and application of an
insecticide.

The names used in these tables are the common
coined chemical names, not the trade names, and as
such may not be familiar to you. For instance, the
common name for Cygon is dimethoate. If there is no
coined chemical name, the trade name is used but is
capitalized.

Requested label clearances for a few uses of some
insecticides, carriers, and solvents is uncertain for 1972,
since many requests have not yet been officially cleared.

ConseqiIeTTRy7=4abels may be cancelled and the product
removed from the market at any time. Anticipating this
we took a conservative attitude a few years ago and be-
gan modifying these suggested uses. We have attempted
to anticipate any further label changes in 1972, but
there still may be an occasional use cancelled. Be sure
to check with your local county extension adviser if
you are not sure about the insecticide you plan to use.
We will make announcements of label changes through
the news media in an attempt to keep you up to date.

Suggestions for use of insecticides, effective from
a practical standpoint, are based on available data.
Many factors affect efficiency of control. Report de-
tails of control failures to us.

In using these tables always read the footnotes be-
fore using the insecticides. They list precautions and
other pertinent information.

Leaflets on specific insects, their life history, habits,
damage, and cultural control methods are available
from the county extension adviser or by writing to
Office of Agricultural Publications, University of Illi-
nois College of Agriculture, Urbana, Illinois 61801.
They are indicated in tables by NHE or Circular
numbers.

Other circulars on insect control are:

Circular 897 — Insect Control for Commercial Vege-
table Crops and Greenhouse Vege-
tables;

Circular 898 — Insect Control for Livestock and Live
stock Barns;

Circular 899 — Insect Control for Field Crops;

Circular 1004 — Pest Control in Commercial Fruit
Plantings.

These are available from the county offices or the Col-
lege of Agriculture at Urbana.

These suggestions are subject to change without
notification during the year.

Suggestions

Aphids (NHE-47)
Leafhoppers (NHE-22)
Mites (NHE-58)
Thrips

Most garden crops malathion

Apply on foliage to control the insects. Aphids and leafhoppers
transmit plant diseases; early control is important. Mites web
on the underside of leaves; apply insecticide to underside of
leaves early before extensive webbing occurs.

Blister beetles (NHE-72)
Cutworms (NHE-77)
Flea beetles (NHE-36)
Grasshoppers (NHE-74)
Leafhoppers (NHE-22)
Picnic beetles (NHE-40)

Most garden crops carbaryl

For cutworms, attach collars of paper, aluminum foil, or metal
at planting for small numbers of plants, or apply insecticide to
base of plants at first sign of cutting. Control grasshoppers in
garden borders when hoppers are small. For picnic beetles,
pick and destroy overripe or damaged vegetables.

Wireworms (NHE-43)
and other soil insects
(NHE-23, 27)

Most garden crops

When tearing up sod for a garden, apply to soil and rake in
before planting.

All cabbage worms
(NHE-45)

Cabbage and
related crops,
salad crops, and
leafy vegetables

bacillus Presence of white butterflies signals start of infestation. Con-
thuringiensis2 trol worms when small. It is almost impossible to raise cole
carbaryl or crops in Illinois without controlling these pests,

1 Do not use oil-base sprays on plants. Do not use malathion on African violets. Do not use carbaryl on Boston ivy. Do not use
diazinon on ferns. Repeated use of carbaryl foliage sprays may cause mite or aphid infestations to increase and become damaging. Do not
use insecticides during full bloom. Do not use dimethoate on chrysanthemums.

Note: E.C. = emulsion concentrate; W.P. = wettable powder. An emulsion concentrate is a chemical pesticide dissolved in a solvent
to which an emulsifier has been added. It can then be mixed with water to the desired strength before being used.

FOR YOUR PROTECTION

1. Store insecticides out of reach of children, irre-
sponsible persons, or animals; store preferably in a locked
cabinet.

2. If you use a bait around or in the home, place it
after the children have retired and pick it up in the morn-
ing before they get up. Furthermore, place it out of their
reach. At present we do not encourage use of baits for
insect control.

3. Avoid breathing insecticide sprays and dusts over
an extended period. This is particularly true in enclosed
areas such as crawl spaces, closets, basements, and attics.

4. Wash with soap and water exposed parts of body
and clothes contaminated with insecticide.

5. Wear rubber gloves when handling insecticide con-
centrates.

6. Do not smoke while handling or using insecticides.

7. Leave unused insecticides in their original contain-
ers with the labels on them and in locked cabinets.

8. Wash out and bury or burn and haul to the refuse
dump empty insecticide containers.

9. Do not leave puddles of spray on impervious sur-
faces.

10. Do not apply insecticides to fish ponds.

11. Do not apply insecticides near dug wells or cis-
terns.

12. Observe all precautions listed on the label.

Spray runways and hiding
places. Repeat treatments
may be needed in 2 or 3
weeks.

Treat under sink, refrigerator, cabinets, on base-
boards, etc. Complete treatment throughout home
may be needed for successful control of brown-banded
roach.

Pantry and
cereal insects
Saw-toothed grain
beetles (NHE-11)
Cigarette beetles

diazinon 0.5% P.S.C.4
Baygon 0.5% P.S.C.4
pyrethrin 0.1% P.S.C.

Spray inside of food
cabinets very lightly and
only after shelves are
empty and cleaned.

Discard infected packages. Scrub or vacuum food
cabinets and shelves. Force spray into cracks and
crevices; allow to dry; cover shelves with clean,
fresh paper. Do not contaminate food or utensils with

'Whenever possible purchase specially prepared ready-to-use forms of insecticides for indoor use. When preparing a quantity of 1
gallon or more of a spray of a desired percentage, use the dilution table on page 8. You need to know only the formulation of the insecti-
cide when using the dilution table.

* Do not use in pet shops or if tropical fish are present. Do not use in kitchens, restaurants, or areas where food is present. Do not
use in nurseries or rooms where infants, ill, or aged persons are confined.

4 For use only by pest control operators. Homeowners should use 0.1% pyrethrin.

Note: E.C. = emulsion concentrate; W.P. = wettable powder; P.S.C. = pressurized spray can; O. = oil solution (usually in pres-
surized spray can).

(SEE PESTICIDE DILUTION TABLE ON PAGE 8)

PESTICIDE DILUTION TABLE

HOW TO USE: When preparing a spray of a de-
sired percentage you need to know only the formulation
of the particular product. (Examples: Kelthane 18.5%
wettable powder; Kelthane 18.5% emulsion concen-
trate.) For instance, if you were preparing a 1%
chlordane solution for spraying the foundation of the
home, you would mix 5 tablespoons of chlordane 45%
E.C. into each gallon of water. The formulations of
insecticides in the following table may be purchased

from hardware stores, pest control establishments, lawn
and garden centers, and other sources. For some jobs,
such as spraying outdoors to control flies or mosqui-
toes, a gallon or more of properly diluted spray is
required. To obtain the percent concentration sug-
gested for controlling a particular insect, add the
amount of pesticide suggested in the following table to
one gallon of water.
