Barrier products are applied according to label guidelines for residential use — we'll flag any areas needing special handling.

Standing water features require a different approach — larvicide — because barrier spray only affects adult mosquitoes, not developing larvae.

A three-week cycle is typical, though heavier rainfall seasons sometimes call for tighter scheduling. It also helps to check for any new containers holding water after storms, since a single overturned bucket can restart breeding within days.
