Pest control

Pest control


To reduce the presence of pests in buildings and minimize occupant exposure to pest-related allergens.


Unhygienic conditions lead to the presence of pests and dust mites, which are common sources of indoor allergens. Their bodies, feces and saliva contain allergens which can trigger asthma and allergic reactions in susceptible individuals. Asthma can also be compounded by sensitivity to other allergens; up to 60% of individuals with asthma who live in urban environments also have a sensitivity to cockroach allergens.
