The MAAIT is a randomized, controlled trial of a home intervention to reduce mouse allergen exposure in mouse allergic children with asthma and mouse allergen exposure. Participants will be randomized to either the Integrated Pest Management (IPM) Group or the Education Group. The IPM Group will receive professional mouse abatement, education, two HEPA filters, allergen-proof mattress and pillow encasements, and targeted cleaning. The Education Group will receive education about IPM at the beginning of the trial and then after completion of the trial, will receive the IPM intervention. Participants will be followed for 12 months.

Primary Outcome Measures:
  • change in asthma symptoms [ Time Frame: 0, 3, 6, 9, 12 months ]
    days of asthma symptoms

Enrollment: 361
Study Start Date: November 2010
Study Completion Date: September 2016
Primary Completion Date: September 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Education Group
This group will receive IPM education at baseline, and then the full IPM intervention after completing the study.
Other: Education
This group will receive education about mouse IPM.
Experimental: IPM Group
This group will receive the full IPM intervention at baseline.
Other: Integrated Pest Management
The IPM intervention will include professional mouse abatement, two HEPA filters, targeted cleaning, education about IPM, and allergen-proof mattress and pillow encasements. The intervention will be delivered at baseline to the IPM Group, and then repeated if recurrent or persistent mouse infestation is present.
