Then it's a bug, and everyone knows what to do with bugs don't they
Eat them. Jump on them. Put down poison. Feed them to the lizard. Put them outside. Pull their legs off. Pull their wings off. Set them on fire. Paint them silver. Coat them with glue and drop them on bare soil. Drop pebbles on them and see how long they last. Pull their cases off. Drop treacle on their backs. Put them in a jar full of water and see how long they last. Freeze them in the freezer and see if they survive. Battle them against each other in an ashtray. Hold them over the kettle with tweezers and see how long they last. If they have a nest, find it, make lots of small holes in ground with garden fork, fill holes with bicarbonate of soda, turn soil over a bit, and then pour vinegar on. Follow up with boiling water and domestos. Or submit them on sourceforge.
