An insect and arachnid trap ( 10, 100 ) comprises a substrate ( 12 ) having a top surface ( 14 ) onto which a sticky substance ( 24 ) is deposited. One embodiment of the trap ( 10 ) is provided with a reinforcing rib ( 26 ) to reinforce the thin sheet substrate. The trap ( 10, 100 ) may also have a channel ( 22, 22 ) into which the sticky substance ( 24 ) is deposited. The top surface ( 14 ) may have a smooth finish and be inclined to the horizontal in order to prevent trapped insects and arachnids from extricating themselves from the sticky substance. The sticky substance is a composition which includes polybutene oil and polyisobutylene. The sticky substance preferably includes 5-15 wt % polyisobutylene. This sticky substance in combination with the channel and smooth top surface provides an insect and arachnid trap which is more effective than known examples. The reinforcing rib ensures that the substrate ( 12 ) does not fold back upon itself when handled after use. Contact with trapped insects or arachnids is thus avoided.
