Onslaught is a micro-encapsulated product. Micro-encapsulated products can take a bit longer to kill insects because the capsules need time to dry out and crack open to release the active ingredient. Most insecticides do not kill bedbug eggs which is why it is so important to do follow up treatments at 7-10 day intervals. Concentrated insecticide sprays should only be one part of a bedbug control program. You should also use an aerosol spray with a straw attachment to get into cracks and crevices and an insecticide dust in wall voids and other concealed areas.
