the highest concentrations of DDT are found at the top of the food chain. in a sense, the top of the food chain gathers and "concentrates" DDT from the rest of the food chain.

Glue traps for mice help administration roaches. they're pre-baited, non-poisonous, and there isn't any scent (except you get those that incorporate anesthetic). in spite of childrens, you may shop them in some troublesome components like below the range, refrigerator, and sinks. I shop a twig bottle of Windex, diluted dish cleansing soap, or perhaps hand cleansing soap around in case I see a roach or ants. I want spraying over smashing. it works speedy; roaches are lifeless interior 30 seconds or so in case you hit them ideal. (It apparently clogs their spiracles and suffocates them.) you basically would desire to be speedy or precise as a results of fact they run like mad after the 1st hit. Comet cleanser is meant to form a barrier that ants won't bypass, yet i'm thinking that would desire to be approximately as poisonous as indoor chemical spraying. somebody mentioned utilising chalk. remember that chalk can incorporate lead, which isn't secure in any quantity for little ones or pregnant women folk, whether ingested or inhaled. and because it somewhat is saved in bone, lead would pose a threat for destiny little ones that an uncovered lady would conceive down the line. there are various large concepts right here; i've got discovered lots!
