bad insect killers

Gooday at my house we have a insect problem and we are trying to get rid of them all butt was not sure witch product to use so we bought 4 different products Doom, Raid, mortien and dyroech.

out of all 4 products Raid was the product that preformed the worst of them all you had to spry the insects multi times before they actually died that was really bad.... mortien game in after raid but the problem their is that as you spray to wards the insect the fine mist is so strong it blows the insect away rather than on it.... then it was dyroach came in third it wasn't bad but it didn't really preform as much as we hoped since its name is dyroach and over all doom preformed the best out of them all
