Treatment by Pest and Location of Infestation
Pests	Material and Formulation	Mixing Directions	Amount per bird or Area if Appropriate	Days to Slaughter	Application and Remarks
Darkling Beetle (Lesser Mealworm)	Sprays
	carbaryl (Sevin) 4F (43% suspension)	50 qts. per 100 gals. water	2 gals. per 1,000 sq. ft.	7	Ventilate while spraying litter surface. Repeat as needed.
	XLR (56.6% suspension)	50 qts. per 100 gals. water	2 gals. per 1,000 sq. ft.	7
	tetrachlorvinphos (Rabon) 50% WP	2 lbs. per 25 gals. water	1 to 2 gals. per 100 sq. ft.	0	Apply thoroughly to litter, walls, roosts, cracks, crevices and interiors
	Dusts
	carbaryl (Sevin) 5% Dust	Ready to use	1 lb. per 40 sq. ft.	7	Do not treat more than once every four weeks. Do not apply to eggs or nests. Clean houses before treatment if mealworms are a great problem (sanitation). Avoid excess gain in litter and moisture. Treat floor litter.
	cyfluthrin (Tempo) 20% WP	Ready to use	19 grams per 1,000 sq. ft.	0	Apply Tempo 20 WP to litter, walls and enter posts inside the house. Best control will be obtained when application is made shortly after bird removal because larvae and adults begin to burrow deeper in the litter as surfave temperatures begin to cool, making control difficult. Use a properly calibrated airblast, boom or power handgun sprayer that will achieve full coverage. Treat only when no birds are present.
	tetrachlorvinphos (Rabon) 50% WP	Ready to use	.75 fl. oz. per 100 sq. ft.	0	Treat litter evenly and thoroughly
	Baits
	carbaryl (Sevin) 10%	Ready to use	24 oz. per 1,000 sq. ft.	0	Spread evenly before new litter is applied or on top of built-up litter. Birds do not have to be removed during application. Optimum treatment is 10 to 14 days after birds are placed in the house. Repeat treatment two weeks later if needed. Follow label directions
