OMEOWNER INSECT PROBLEMS 



t 



, agworm hatch is about complete in the southern sections, and sprays should be applied im- 

 ! ediately. The target date for spraying in the central sections is after June 15; in the 



orthern sections, after June 30. Bagworms especially like to feed on evergreens (except 



ews) , but they will also attack other trees and shrubs. 



ake plans to apply treatments early this year, xvhile the worms are still small and easy 

 o kill and before damage is evident. Carbaryl (Sevin) , diazinon, or malathion are all 

 ffective. Malathion will also provide fair control of the mites that may be present, 

 j ollow label directions and check the list of plants on the label for the ones that may be 

 njured if sprayed with the insecticide you are using. 



.phids are heavy on many kinds of trees, shrubs, and flowers. These small, soft -bodied, 

 ucking insects (green, yellow, black, or red) secrete a sticky material called "honeydew." 

 his sugary secretion coats leaves, making them glisten. Cars parked beneath infested 

 rees become covered with sticky spots. Ants are often numerous on aphid- infested plants, 

 here they feed on the aphid secretions. 



hite specks are usually visible on the leaves; these are the cast-off skins of the aphids-- 

 iOt eggs. The leaves of heavily infested plants will curl, yellow, and eventually brown. 



; or control, spray the foliage thoroughly, using 2 teaspoons of 50- to 57-percent mala- 

 Mon or a 25-percent diazinon emulsion concentrate per gallon of water. Do not use mala- 

 :hion on African violets or cannaert red cedar. Do not use diazinon on ferns or hibiscus. 



iuonymous scale crawlers are now moving out on the leaves and new growth. They will soon 

 : orm a protective covering, making control difficult. If your euonymous has a history of 

 icale problems, apply a malathion spray immediately. Repeat the treatment twice more at 

 /eekly intervals. To mix, use 2 teaspoons of the 50- to 57-percent malathion liquid con- 

 :entrate per gallon of water. 



lie " dive bombers" are back again. There are a large number of mosquitoes in many areas, 

 irobably as a result of the wet weather during recent weeks. To reduce the number of mos- 

 luitoes in home yards, follow these steps: (1) Eliminate standing water in such places 

 is eave troughs, old tires, tin cans, childrens' toys, storm sewers, etc. (2) Apply a 

 /ater-base spray containing 1-percent malathion (2 ounces of 50- to 57-percent liquid con- 

 :entrate per gallon of water) to shrubbery and tall grass. Repeat the treatment every 

 ;eek or two if needed. (5) Keep the screens on doors and windows in good repair. (4) Hang 

 )lastic resin strips (2" x 10") containing 20-percent dichlorvos (DDVP)--one strip per 

 L,000 cubic feet of space, or about one per room. These strips will kill mosquitoes and 

 •lies for 4 to 6 weeks. As an added precaution, hang the strips where children cannot 

 'each them and away from fish bowls and food counters. A 0.1 -percent pyrethrum space 

 ;pray- -applied from a pressurized spray can- -can be used for quick knockdown in place of 

 :he dichlorvos resin strips. Frequent treatments will be needed during problem periods. 

 ^5) When entering mosquito- infested areas, use a repellent. One of the most -effective 

 rosquito repellents is DEET (diethyltoluamide) . (6) For quick knockdown at cookouts, out- 

 loor parties, or picnics, use either 0.1-percent pyrethrum or 0.5-percent dichlorvos 

 (DDVP) as an oil- or water-base space spray. Spray the mist lightly beneath tables and 

 :hairs and into the air for a few feet around the area. Repeat the treatment as needed. 



Tie number of fleas on dogs and cats is increasing. If left uncontrolled, they can be- 

 :ome a serious problem in a home or home yard by late summer. The worm (larva) stage _ 

 3f fleas live in the bedding of dogs and cats, rugs, upholstered furniture, and even in 

 :he dirt in flower and shrubbery beds. The worm stage is usually not noticed and is 

 larmless, but adult fleas suck the blood of warm-blooded animals. Your dog or cat is a
