Cover all drinks
Only serve drinks in covered cups or bottles, and drink through a straw. This is particularly important if your drink is sweetened. If you don’t have covered cups, use aluminium foil and poke a hole for a straw.
Light some candles
Smoke repels mosquitoes and flies. Tiki torches and citronella candles add ambiance to outdoor entertaining, anyway. Plus, they’re affordable, effective and have a pleasant scent.
Float your table
The best way to keep ants off your table is to put the feet in wide containers filled with water. Ants won’t be able to make it across the water to climb up.
