egg case is 4–5mm in length and contains about 16 EGGS. Blattella germanica, the German cockroach, found in most parts of the world.Spurgeon, while warning that his assessments are ''real subjective--your opinion is as GOOD as mine,'' figures that an INSPECTION turning up one to five roaches per room indicates light infestation, 10 to 25 visible per room indicates MODERATE infestation and more than that equals heavy infestationCockroaches do not have red blood because they do not use hemoglobin to carry oxygen. They do not carry oxygen in their blood stream either. Most cockroach's blood is colorless.To repel roaches, try mixing two parts water with one part white VINEGAR and 10 drops of peppermint oil to a spray bottle, and spritz it around the affected areas of your apartment. |
