Davus Fasciatus is a very skittish and defensive tarantula but not considered really aggressive. When they feel threatened, they will kick urticating hairs as a defense and are very avid hair kickers. Before kicking their hairs, they can give a defensive threat posture to warn their aggressor.

Handling & Bite

It is not recommended to handle this species due to their defensive nature and how little it takes for them to kick their urticating hairs. These tarantulas should be left to a more intermediate tarantula keeper that wants a little more aggressive species than a dolce species.

Their venom is not very dangerous to humans, but it will cause intense pain around the bite as well as fevers, chills, swelling, and itchiness. Severe muscle cramps are unlikely like with most new world tarantula species, and it is recommended to seek medical aid as you may be allergic to tarantula venom.

Davus Fasciatus Feeding

The costa rican tiger rump is a very good eater and should be fed at least once every two weeks. They can be fed crickets as well as Dubai roaches when adults. When feeding a small spiderling, they can be fed crush crickets to reduce the risk of injuries or pinhead crickets.

Davus Fasciatus Tarantula Care

The tiger rump is generally easy to take care for and do not require much as long as the temperature, humidity, and cleanliness of their enclosure is kept in ideal conditions.

Tank / Habitat

The tiger rump like temperatures to be kept between 72 to 75°F with a humidity around 75 to 80%. it is recommended to keep the substrate of the enclosure moist but not wet. If the substrate is too wet you will notice that the tiger rump will stay on the side of the habitat or on top of their hiding spots/bark etc. It is important that your enclosure has a water dish and it is full of fresh water at all times.

For younger sling setups they can be kept in pill jars keeping the substrate a little more moist as it’s not likely to fit in a water dish at this stage.

When davus fasciatus is more into the juvenile stage, they can be rehoused into a deli container with air holes drilled into the container or a critter keeper.

Once the costa rican tiger rump has reached adulthood, it can be rehoused into a 2-gallon enclosure

As far as substrate, potting soil or eco earth is recommended, and a fair amount should be added as this species is an opportunistic burrower, meaning they prefer to burrow when they are given the opportunity.
