Sticky traps

The sticky trap method uses a sticky compound or sticky tape. They are not used very frequently, and we have not heard that this is a particularly useful approach, so we have included it here for completeness only. If you work on invasive ants and find these are useful please let us know.

Tanglefoot is the standard trapping compound used for this type of sampling. The product is available in either a sticky paste, which needs to be applied with a spatula or in a less sticky brushable form. Tanglefoot is non-toxic and is marketed as environmentally friendly. 

Comparable results have been described using double-sided foam tape attached to the tree.

Tree sampling

The Tanglefoot compound is spread thinly over a strap of 2.5 cm wide grease-proof tape stapled to the trunks of trees along a 100 X 5 m transect.

Care must be taken on rough barked trees that there is no space under the tape for ants to crawl though. This can be done by securing the tape tightly over a layer of cotton wool, soft fabric or tissue (e.g. toilet tissue).

Ground sampling

Sticky trap sampling may also be used for sampling ants that live or forage on the ground.

This method uses double sided tape and an attractive lure such as jam, tuna or peanut butter.

The centre of a 120 mm strip of 15 mm double sided tape is spread with jam, tuna or peanut butter.

The tape is then placed inside a 150 mm length of clear plastic tube with a 25 mm internal diameter. 

The traps are placed along a transect at 20 m intervals.
